Atacama Desert Tours: Exploring Valle de la Luna in Chile
Atacama’s Valley of the Moon: wander among sand‑sculpted wonders and otherworldly dunes with this enchanting travel guide — including tours of Atacama Desert highlights to make your visit unforgettable.
Updated | October 2026
Why Visit Valle de la Luna? One of the Best Atacama Desert Tours
Just 8 miles (13 km) west of San Pedro de Atacama, Valle de la Luna (Valley of the Moon) is one of the most remarkable landscapes in northern Chile. Located within the Cordillera de la Sal, this protected area was declared a Nature Sanctuary in 1982 and is also part of Los Flamencos National Reserve.
Its name comes from the landscape's striking resemblance to the surface of the moon. Over millions of years, geological uplift, wind and occasional water erosion have shaped layers of salt, clay and sedimentary rock into jagged ridges, unusual formations and enormous dunes. The result is a landscape that feels almost unreal, but one with a fascinating geological story behind every formation.
Among the many Atacama desert tours departing from San Pedro de Atacama, Valle de la Luna is particularly rewarding for its extraordinary geology, dramatic scenery and changing light. From exploring sculptural rock formations to watching the desert shift colors as the sun begins to set, it's an experience that reveals just how varied and remarkable the Atacama Desert can be.

My Bibimbap Moment
This trip added: Otherworldliness.
Valle de la Luna added the ingredient of otherworldliness to my Bibimbap Life. I had never seen a landscape quite like it. The heat seemed to intensify the strangeness of the surroundings, while the formations and vast stretches of barren earth made me feel as though I'd somehow wandered onto another planet. At each stop, the landscape revealed another shape or texture I couldn't quite reconcile with anything familiar. Then, as the sun began to set, everything softened into warmer shades and we watched the day disappear with snacks in hand. It was strange, beautiful and completely unlike anywhere I'd been before.
My Two-Week Chile Travel Itinerary
Our two weeks in Chile covered an incredible range of landscapes, from the busy streets of Santiago and the arid Atacama Desert to the glaciers of Patagonia and the coastal traditions of Chiloé Island. With eight flights, countless buses and taxis, a ferry and a few unexpected detours, getting between destinations was an adventure in itself.
We began in Santiago, exploring its markets, restaurants and colorful streets while recovering from the long journey. From there, we headed north to San Pedro de Atacama, our base for several unforgettable desert excursions. We visited the flamingos at Laguna Chaxa, the mineral-rich landscapes of Piedras Rojas, the high-altitude Altiplanic Lagoons and the steaming geysers of El Tatio. We also explored the extraordinary rock formations and dunes of Valle de la Luna, followed by a separate evening of stargazing beneath the Atacama's remarkably clear skies.
Next, we traveled south through Punta Arenas before continuing to Torres del Paine National Park, where we stayed at Las Torres and explored a landscape of mountains, waterfalls, glaciers and brilliant blue lakes. The contrast with the desert couldn't have been more dramatic.
Our final destination was Chiloé Island, where we based ourselves around Castro and discovered distinctive wooden churches, coastal scenery and a culture shaped by maritime traditions and local folklore.
It was an ambitious itinerary but experiencing Chile's remarkable geographical diversity made every long travel day worthwhile.
Our route: Santiago → San Pedro de Atacama → Punta Arenas → Torres del Paine → Chiloé Island (Castro)

Exploring Valle de la Luna: Highlights of Our Atacama Desert Tour
Just outside San Pedro de Atacama, Valle de la Luna offers an extraordinary look at the geological forces that have shaped the Atacama Desert. From unusual salt and rock formations to enormous dunes and panoramic viewpoints, each stop reveals something different about this remarkable landscape.
Our guided tour took us through some of Moon Valley's most distinctive features, including Las Tres Marías, the Amphitheater, the Great Dune and Piedra del Coyote, before finishing with sunset over the desert. Along the way, we learned about the region's geology, explored its unusual terrain and experienced some of the most memorable views of our time in northern Chile.
Las Tres Marías — The Three Marys
Our afternoon Valle de la Luna tour began with our guides, Constantine and Marco, who introduced us to the remarkable geology of the Cordillera de la Sal. A short drive from San Pedro de Atacama brought us into a landscape of exposed ridges, salt deposits and unusual rock formations. Over the next few hours, we'd explore several of the valley's most distinctive features before finishing with sunset over the desert.
One of our first stops was Las Tres Marías (The Three Marys), a group of naturally sculpted rock pillars rising from the otherwise open desert floor. Their irregular silhouettes are said to resemble three human figures, although a little imagination helps. The formations contain a mixture of sedimentary material and minerals, including clay, quartz, salt and gypsum, gradually shaped by erosion over an immense period of time.
Interestingly, the formations were originally known as Los Vigilantes (The Guards). According to the Indigenous association that manages Valle de la Luna, the area also held ceremonial significance for the ancient Atacameño people, who performed rituals honoring the Earth. It's a reminder that this landscape has cultural meaning extending far beyond its unusual appearance.
The formations are also surprisingly fragile. Over time, natural erosion has continued to change their shapes and one of the original pillars was reportedly damaged by a visitor who climbed onto it. Today, protective barriers help prevent further damage.
ℹ️ Good to Know | Las Tres Marías is generally a short stop on guided Atacama desert tours but it's worth taking a moment to look closely at the different colors, textures and mineral layers. Stay behind the barriers and avoid touching or climbing the formations — the same processes that created them also make them vulnerable to damage.
The Amphitheater
Our next stop was the Amphitheater, one of the most distinctive formations in Valle de la Luna. Its enormous, curved rock walls rise from the desert floor, resembling the seating of a natural amphitheater. From a distance, the scale is impressive but the closer you look, the more interesting the geology becomes. Layers of sediment, pale mineral deposits and sharply eroded ridges reveal a landscape that has undergone extraordinary changes over millions of years.
The Amphitheater is part of the Cordillera de la Sal (Salt Mountain Range), where ancient sedimentary deposits were gradually compressed, folded and uplifted by tectonic forces. What were once relatively horizontal layers of sand, clay, silt and evaporite minerals now appear tilted, bent and exposed across the desert. The different colors and textures make these geological layers particularly visible, almost like looking at a cross-section through the Earth's history.
Interestingly, the Amphitheater contains rocks from the Vilama Formation, which includes fine-grained sediments and layers of volcanic ash deposited during eruptions in the Andes. Geological movements have also shifted blocks of rock along faults, placing older formations beside younger ones rather than neatly stacked beneath them. It's a fascinating example of how dramatically the Earth's crust can rearrange itself.
How Salt Helped Shape the Landscape
One of the most interesting features of Valle de la Luna is the abundance of salt embedded throughout the surrounding rock. The region's geological history includes ancient saline environments where minerals accumulated as water evaporated, leaving deposits of salt and gypsum mixed with sedimentary layers.
The Atacama is part of a largely endorheic drainage system, meaning water collects within inland basins rather than flowing directly to the ocean. When occasional rainfall dissolves salts from exposed rock, that mineral-rich water can move through the ground or across the surface. As it evaporates, the dissolved minerals crystallize again, sometimes forming the bright white crusts and deposits visible against the darker earth.
This process continues today, although it works alongside much larger geological forces. Tectonic uplift and folding created the underlying structures, while wind, occasional water erosion and the dissolution of salt have gradually worn away softer material. The result is an extraordinary combination of steep ridges, narrow gullies, exposed sedimentary layers and unusual mineral formations.
The area's salt deposits also have a human history. Before Valle de la Luna became a protected tourist destination, parts of the valley were used for small-scale salt mining. The area was once known as Las Salinas, and remnants of this activity remain part of its history. One former operation, Mina Victoria, was named by its owner, Gabino Aguilar, in honor of his wife, Victoria Vilca.
A Landscape That Continues to Change
What makes this part of the Atacama Desert so unusual is how clearly its geological history is exposed. With very little vegetation covering the terrain, the folded ridges, eroded slopes and contrasting mineral deposits are visible across enormous stretches of the valley. Shades of ochre, gray, brown and white reveal different materials, while the changing afternoon light makes their shapes and textures even more pronounced.
The landscape is still evolving. Although rainfall is extremely limited, occasional storms can reshape exposed surfaces, while strong winds continue to move loose sediment and wear away vulnerable formations. Even salt plays a role: when moisture dissolves it and evaporation causes it to crystallize again, small changes gradually accumulate across the terrain.
There's also an interesting connection between the Atacama Desert and space exploration. NASA has used parts of the desert as testing grounds for instruments designed to search for life on Mars. The region's extreme dryness, salty soils and harsh environmental conditions make it useful for studying how life might survive in similarly challenging environments beyond Earth. While these experiments weren't necessarily conducted in Valle de la Luna itself, the resemblance between the desert's barren terrain and images of Mars is easy to appreciate.
And the geology reaches much further into the past. Geological evidence from northern Chile includes marine fossils and sediments associated with ancient seas, helping scientists reconstruct how dramatically this region has changed. Although these fossils aren't something visitors should expect to find along the Amphitheater trail, they offer another fascinating connection to the area's distant history.
By the time we'd finished exploring the Amphitheater and its surrounding formations, we'd seen an extraordinary range of textures, colors and geological features. But the next stop would offer an entirely different perspective. Leaving the road behind, we followed our guide into the soft sand and began the climb toward Valle de la Luna's Great Dune.
The Great Dune
After exploring the Amphitheater, our guide led us away from the road and toward Duna Mayor (the Great Dune), one of the highlights of our Valle de la Luna tour. The climb looked manageable from below but the soft sand made every step more difficult than expected. Combined with the afternoon heat, it was a slow, sweaty ascent. Thankfully, the views only got better as we climbed.
The Great Dune is particularly interesting because of its location among the rocky formations of the Cordillera de la Sal. Unlike the surrounding ridges, which were formed through sediment deposition, tectonic movement and erosion, the dune developed as wind carried and accumulated sand eroded from older rocks. Over time, that loose sediment collected against the surrounding terrain, creating a striking contrast between smooth sandy slopes and sharply folded rock formations.
As we climbed higher, the landscape opened in every direction. On one side, an enormous drop revealed jagged cliffs and deeply eroded ridges. On the other, soft dunes rolled across the valley, interrupted by scattered rocks and patches of pale mineral deposits. The contrast was extraordinary, and it became even more dramatic from the top.
From the viewpoint, we could see the Cordillera de la Sal stretching across the desert, its ridges marked by exposed layers of rock and pale deposits of salt and gypsum. A narrow road cut through the otherwise open landscape, providing a surprisingly useful sense of scale. Some formations rose in sharp, almost serrated lines, while others had been worn into smoother, rounded shapes.
What I found most fascinating was how these completely different textures existed side by side. The windblown sand looked almost soft enough to touch, while the surrounding rock formations appeared hard, brittle and deeply fractured. Looking across the valley, it was easy to appreciate how different geological processes had shaped the same landscape.
Near the top, wooden posts connected by chains marked the edge of the designated viewing area. Beyond them were some rather intimidating drops, making the barriers feel especially necessary. A ranger sat beneath a small thatched shelter, watching over visitors in the intense afternoon sun. I remember wondering what it must be like to spend your working days surrounded by such an unusual landscape.
The views from Duna Mayor were among my favorites of our entire visit to San Pedro de Atacama. There was something remarkable about seeing the valley from above after spending the afternoon walking among its individual formations. From this perspective, the relationship between the dunes, salt deposits, ridges and open desert became much easier to understand.
Eventually, it was time to head back down. Fortunately, descending through the soft sand was considerably easier — and much more enjoyable — than climbing up. We made our way back toward the van, leaving the panoramic views behind and continuing to the next stop on our Atacama desert tour.
💡 My Tip | Don't underestimate the climb simply because the trail is relatively short. Loose sand, strong sun and the elevation can make it surprisingly tiring. Take your time, bring water and stay within the marked viewing areas, particularly near the steep drop-offs.
Piedra del Coyote — Panoramic Views from Mirador de Kari
After descending the Great Dune, we climbed back into the van and continued toward Mirador de Kari (Ckari), one of the best-known viewpoints near San Pedro de Atacama. Sitting approximately 8,350 feet (2,545 meters) above sea level, the lookout offers a sweeping view across the Cordillera de la Sal and the surrounding desert.
What struck me most was the contrast in the landscape. From above, the jagged ridges and deeply eroded ravines seemed to end almost abruptly, giving way to a remarkably flat expanse of desert. Beyond that, distant mountains rose along the horizon. After spending the afternoon surrounded by individual rock formations, it was fascinating to see how dramatically the terrain changed across such a relatively short distance.
The viewpoint is also famous for Piedra del Coyote (Coyote Rock), a rocky overhang projecting from the edge of the cliff. Its precarious appearance immediately brings to mind Wile E. Coyote and the Road Runner cartoons — the sort of ledge where you'd expect the coyote to stand for a moment before realizing there's nothing beneath him.
But the cliff edge is no cartoon. The ground is made up of fractured, weathered rock and loose material, with steep drop-offs overlooking the valley below. The same geological forces that folded and uplifted the Cordillera de la Sal, followed by erosion over millions of years, have helped create this dramatic landscape. It's a striking place to appreciate both the scale of the desert and the fragility of its formations.
As the afternoon light shifted, the ridges cast longer shadows across the valley, making their folds and irregular shapes even more visible. It was another memorable stop on our Atacama desert tour and a wonderful final perspective on the landscapes we'd spent the afternoon exploring.
ℹ️ Good to Know | Mirador de Ckari has been closed since May 27, 2026, pending a safety assessment following an earthquake. The closure remains listed on the official Valle de la Luna website, so check current access before planning a visit. Guided tours may use alternative viewpoints while the lookout is unavailable.
Sunset Over the Atacama Desert
After an afternoon exploring Valle de la Luna, our final stop was a viewpoint overlooking the Cordillera de la Sal, where we'd watch the sun set over the desert. The landscape looked completely different in the softer evening light. Ridges that had appeared harsh and sharply defined throughout the day began to take on warmer shades of ochre, pink and lavender, while long shadows brought out the folds and textures of the surrounding rock formations.
It was a lovely way to finish our Atacama desert tour, especially after spending several hours walking through the heat and climbing the Great Dune. Instead of rushing back to San Pedro de Atacama, we had time to relax and enjoy the changing scenery.
While everyone admired the views, our guides prepared an impressive spread of snacks and drinks. There was chilled fresh juice, local wine, fruit, olives, cheese, nuts and pita chips with guacamole. After an afternoon in the desert, it was a particularly welcome surprise — and much more generous than the few snacks I'd expected.
As the sun dropped lower, the colors continued to change. The rocky ridges became softer in the fading light, with pale mineral deposits standing out against the darker slopes. From our viewpoint, we could see how the afternoon shadows emphasized the uneven terrain, revealing details that had been less noticeable earlier in the day.
One of the most interesting things about photographing Valle de la Luna is how dramatically the landscape changes with the position of the sun. The same ridges and mineral formations can look completely different depending on the angle of the light, which makes late afternoon especially rewarding for photography.
Eventually, it was time to return to San Pedro de Atacama but our day wasn't quite finished. Later that evening, we'd head back into the desert for a separate stargazing tour, trading the warm colors of sunset for a closer look at the extraordinary night sky.
Between the unusual rock formations, the climb to the Great Dune, the panoramic viewpoints and this peaceful finish, Valle de la Luna had been one of the most memorable excursions of our time in northern Chile.
My Bibimbap Moment
Every destination adds another ingredient to our life's recipe, sometimes by showing us something we've never quite seen before. In Valle de la Luna, the landscape seemed to stretch the limits of what I thought a desert could look like — towering rock formations, strange shadows, endless mineral textures and colors that shifted as the sun moved across the valley. From the Three Marys to Moon Valley's peak and the view from Piedra del Coyote, every stop felt like another glimpse into an entirely unfamiliar world. Here's the ingredient the Atacama added to my Bibimbap Life.

🎒 Take With You: Some landscapes feel less like somewhere you've arrived and more like somewhere you've imagined. Valle de la Luna was one of those places.
When I think back on Valle de la Luna, I remember the feeling of looking at something that didn't seem entirely real. The Three Marys, the Amphitheater, the vastness from the peak and Piedra del Coyote all felt like different versions of the same strange dream. The heat was intense, the landscape almost completely bare and yet there was so much to look at. By sunset, sitting with snacks and watching the light change across the desert, I found myself simply taking it all in. Some places are beautiful because they're familiar; Valle de la Luna was beautiful because I couldn't compare it to anything at all.
Valle de la Luna Travel Essentials
Valle de la Luna is one of the most accessible excursions from San Pedro de Atacama, making it an easy addition to your time in northern Chile. Located just 8 miles (13 km) outside town, it's typically explored on a half-day tour, with late afternoon visits especially popular for the changing light and sunset views. The desert's intense sun, dry conditions and significant temperature changes make a little preparation worthwhile, so bring plenty of water, sun protection and an extra layer for the evening. Whether you're joining a guided tour or visiting independently, allow enough time to explore the valley's distinctive rock formations, dunes and viewpoints without rushing.
When to Go
Late afternoon is the best time to visit Valle de la Luna, when the lower sun brings out the colors and textures of the desert's salt formations, rocky ridges and dunes. Many guided tours from San Pedro de Atacama are scheduled around sunset, allowing time to explore the valley before enjoying panoramic views as the light changes.
Time of Day: Plan for a late-afternoon visit, with departure times varying by season. Sunset tours often leave San Pedro de Atacama earlier in winter and later in summer. Confirm the itinerary and designated sunset viewpoint with your tour operator, as access and closing times can change.
Best Season: Valle de la Luna can be visited year-round. Spring (September–November) and autumn (March–May) generally offer a comfortable balance of temperatures and manageable crowds. Summer (December–February) brings stronger daytime heat, while winter (June–August) can be especially cold after sunset. Bring layers regardless of the season.
How to Get There
Valle de la Luna is located approximately 8 miles (13 km) west of San Pedro de Atacama, making it one of the easiest excursions to organize from town. Most visitors arrive on a guided half-day tour, although it's also possible to explore independently by rental car or bicycle.
Guided Tour: Joining one of the many Atacama desert tours departing from San Pedro de Atacama is the easiest option, especially if you're interested in learning about the valley's geology and history. Most tours include transportation between the main viewpoints and geological formations, with afternoon excursions often timed around sunset. Check whether the reserve's entrance fee is included in your booking.
Rental Car: You can drive to Valle de la Luna independently in approximately 15–20 minutes from San Pedro de Atacama, following Route 23 toward Calama. Having your own vehicle gives you more flexibility but you'll need to purchase an entrance ticket in advance and follow the reserve's designated routes, opening hours and access restrictions.
Bicycle: Cycling from San Pedro de Atacama is another option, particularly for active travelers comfortable riding in the desert. The entrance is roughly 8 miles (13 km) from town but you'll also cover additional distances between attractions within the reserve. Cyclists have restricted morning entry hours and must carry water and appropriate safety equipment. Be prepared for intense sun, exposed terrain and a longer ride than the distance to the entrance might suggest.
Getting to San Pedro de Atacama: Most travelers fly from Santiago to El Loa Airport (CJC) in Calama, a flight of approximately two hours. From the airport, San Pedro de Atacama is another 1–1.5 hours away by shared or private transfer. Rental cars are also available, while budget travelers can take a bus from Calama's town terminal. Long-distance buses connect San Pedro with other destinations in northern Chile, although traveling overland from Santiago takes considerably longer.
💡 My Tip | For a first visit, I'd recommend a guided tour. Having someone explain the geological formations and history adds another dimension to the experience, and you can concentrate on exploring and photographing the landscape rather than navigating between stops.
✈️ Travel Tip | If you're visiting independently, purchase your entrance ticket through the official Valle de la Luna website before arriving. Entry hours vary by season and cyclists have an earlier entry cutoff than motorized visitors.
Where to Stay
San Pedro de Atacama is the best base for exploring Valle de la Luna and the surrounding desert, with plenty of accommodation options ranging from simple guesthouses to boutique hotels and peaceful desert retreats. Staying near the town center makes it easy to walk to restaurants, shops and tour operators, while properties a little farther out often offer more space, quieter surroundings and a welcome escape from the heat.
Where I Stayed in San Pedro de Atacama
For a Peaceful Desert Retreat — Casa Solcor Boutique Bed & Breakfast
We stayed at Casa Solcor Boutique Bed & Breakfast, just outside the center of San Pedro de Atacama, and it was nearly perfect. The peaceful atmosphere, lovely pool, comfortable lounging areas and delicious breakfast made it a wonderful place to unwind between excursions. Town was only about a 10–15-minute walk away, although the desert heat made that short distance feel considerably longer during the day. For us, the tranquility and space were well worth it.
Where I’d Stay in San Pedro de Atacama
If I were planning another visit to San Pedro de Atacama, these are a few places I'd consider for their thoughtful design, inviting atmosphere and convenient locations. Each offers a slightly different experience, from intimate boutique accommodations to a peaceful retreat after a day exploring the desert.
For a Quiet Boutique Stay — Hotel Pascual Andino
A small, welcoming boutique hotel with just 10 rooms, located one block from San Pedro's main street. The rooms feature exposed adobe-style walls, wood finishes and private patios, while a seasonal pool and included breakfast make it a comfortable place to relax between excursions. It's an appealing option if you prefer intimate accommodations but still want restaurants and tour agencies within easy walking distance.
For Design & Desert Atmosphere — Hotel Desértica
One of the more interesting design-focused stays in San Pedro de Atacama, Hotel Desértica occupies a former Atacameño orchard just a short walk from the town center. Its circular guest rooms draw inspiration from traditional local construction, while the property also has a lovely pool, inviting outdoor lounges and an on-site restaurant. A particularly appealing choice if you appreciate thoughtful design and somewhere peaceful to return to after a day exploring the desert.
Additional Options
For a Historic Boutique Splurge — Hotel Terrantai
Located in the historic center of San Pedro de Atacama, Hotel Terrantai occupies a restored 19th-century property that celebrates the region's traditional architecture. Adobe, stone, wood and local craftsmanship give the interiors a strong sense of place, while recent renovations introduce contemporary comforts without losing the building's character. Its central location is particularly convenient for walking to restaurants and exploring town. A lovely option for travelers who appreciate historic buildings, thoughtful restoration and a more intimate hotel experience.
Prefer a Place of Your Own in San Pedro?
A private apartment, casita or vacation rental can be a great alternative, especially if you're staying several days or prefer a little more independence. Having your own kitchen and outdoor space can make it easier to settle into the slower rhythm of desert life between excursions. Look for somewhere within walking distance of the town center if you won't have a rental car and check for shade or cooling options during the warmer months.
How to Get Around
San Pedro de Atacama is small and easy to explore on foot, with most restaurants, shops and tour operators clustered around the town center. Just keep in mind that the desert sun can make even a 10–15-minute walk feel much longer, especially in the middle of the day.
For exploring beyond town, guided Atacama desert tours are often the easiest option, with transportation included to places like Valle de la Luna, El Tatio Geysers and the Altiplanic Lagoons. Renting a car gives you more flexibility, although some destinations involve long drives and rough roads. Bicycles are also popular for nearby attractions but the heat, elevation and lack of shade are worth considering. Unless you're planning to explore extensively on your own, you can comfortably enjoy San Pedro de Atacama without a car.
How Long to Stay
Valle de la Luna is best explored on a half-day excursion from San Pedro de Atacama, with most guided tours lasting around 4–5 hours, including transportation and time at the main viewpoints. An afternoon tour is particularly worthwhile if you want to experience the changing colors of the desert as sunset approaches.
For the wider Atacama Desert, I'd recommend spending at least 3–4 full days in San Pedro de Atacama to explore beyond Moon Valley. This gives you time for other memorable excursions, including El Tatio Geysers, Piedras Rojas, the Altiplanic Lagoons and stargazing, without packing every experience into a single day. If you have the flexibility, five days allows for a more relaxed pace, especially when factoring in early departures, long drives and time to adjust to the altitude.
Tours & Day Trips
San Pedro de Atacama is an excellent base for exploring northern Chile, with guided excursions reaching everything from salt flats and high-altitude lagoons to geothermal fields and some of the clearest night skies in the world. Local operators offer a wide range of Atacama desert tours, making it easy to combine several experiences during your stay without needing to rent a car.
For Valle de la Luna, I'd recommend a guided afternoon tour. Having someone explain the valley's unusual geology and history adds so much to the experience and transportation between the main stops makes the visit straightforward. Local operators such as Turismo Gato Andino offer half-day excursions or you can compare other Moon Valley tours to find the group size, itinerary and departure time that suit you best.
💡 My Tip | San Pedro has plenty of tour agencies and visiting a few in person can be a good way to compare excursions and ask questions. However, I'd book ahead if you're traveling during a busy period or have limited days available. Some protected areas also require separate advance entrance reservations, so always check what's included in the tour price.

What to Bring
Valle de la Luna is beautiful but exposed, with little shade, sandy trails and rocky terrain that can be surprisingly challenging in the desert heat. You won't need specialized hiking equipment for most guided tours but a few essentials will make the experience much more comfortable.
Comfortable Walking Shoes: Sturdy sneakers or lightweight hiking shoes with good grip are ideal for loose sand, uneven paths and rocky sections.
Sun Protection: Bring a wide-brimmed hat, sunglasses and high-SPF sunscreen. The sun is intense, even when the wind makes the air feel cooler.
Plenty of Water: Carry a refillable water bottle and drink regularly. The extremely dry air makes it easy to underestimate how much water you're losing.
Warm Layers: A lightweight fleece or jacket is useful for late-afternoon tours, especially when the wind picks up and temperatures begin to fall.
Lip Balm & Moisturizer: The combination of dry air, sun and wind can be tough on exposed skin.
Camera or Phone: The unusual formations, enormous dunes and changing light make Valle de la Luna particularly rewarding for photography. A wide-angle lens is great for capturing the scale of the landscape.
💡 My Tip | Don't forget to protect your ears. Mine got badly sunburned during our first day in the Atacama Desert, despite being careful with sunscreen elsewhere. A hat with good coverage is worth bringing.
Good to Know
Valle de la Luna is part of a protected desert environment, so visiting involves a few more considerations than simply arriving and exploring. Access is regulated, certain areas are restricted and the landscape is more fragile than it might initially appear.
Entrance Tickets & Access: Independent visitors should arrange admission through the official Valle de la Luna website before arriving. Guided tours may handle ticket arrangements differently, so confirm what's included when booking. Opening hours, designated viewpoints and access restrictions can change.
Stay on Designated Trails: The valley's salt formations, sedimentary layers and delicate surfaces can be damaged by foot traffic. Follow marked paths and respect barriers, even when a nearby ridge looks tempting to explore.
Altitude & Conditions: Valle de la Luna sits at approximately 8,200 feet (2,500 meters) above sea level. Although it's lower than many other excursions from San Pedro de Atacama, the elevation, intense sun and dry climate can still make walking more tiring than expected.
🌍 One Last Thing | The Cordillera de la Sal (Salt Mountain Range) was shaped by geological processes spanning millions of years. Ancient sediment deposits, including salt-rich minerals, were compressed, folded and uplifted through tectonic activity. Erosion gradually exposed the layers, creating the ridges, cliffs and unusual formations that give Valle de la Luna its distinctive appearance.
