Adventure into the Indian Ocean off Sri Lanka’s southern coast with this travel guide.

Mirissa sits on Sri Lanka’s sun-drenched southern coast — the final, unforgettable stop on my three-week whirlwind through this island of contrasts. More than just a beach town, Mirissa hums with a laid-back charm: palm-fringed bays, surfable swells and seafood stalls that perfume the air with smoky curry and grill.

Sri Lanka itself felt like a well-kept secret — a compact mix of ancient temples, teeming wildlife and emerald hills that tumble to golden shores in the Indian Ocean, tucked near the Bay of Bengal and brushing maritime borders with both the Maldives and India. The land unfurls a mosaic of wonders: towering ancient ruins like the fortress-rock of Sigiriya that whisper stories of kings and legend; the sacred, jewel-bearing Temple of the Tooth in Kandy that pulses with ritual and history; and raw, unforgettable safaris where elusive leopards and lumbering elephants move through wild landscapes.

Mirissa pulses with maritime life: the largest fishing port on Sri Lanka’s southern coast, it overflows with fresh tuna, mullet, snapper and buttery fillets hauled in by dawn. By day the bay is a playground — whale-watching boats cutting through glassy water, surfers chasing perfect breaks and deep-sea fishermen testing their luck. Golden beaches stretch as far as the eye can see, skirted by palm shade and postcard-perfect sunsets. When night falls, Mirissa hums with beachfront bars and lively crowds and just a short ride away the historic ramparts and charming lanes of Galle Fort offer a quieter, timeless contrast.

Three unforgettable weeks traversing Sri Lanka felt like stepping into a sweaty dream. We started just north of Colombo and traced a clockwise loop around the island, our first pause at Pinnawala to watch elephants amble and splash at a local sanctuary. Each day forward unfolded new textures — from misty hill stations and tea-scented valleys to sun-baked beaches and bustling market towns — turning the island’s familiar map into an unexpected, richly layered journey.

Dried earth stretched out before us as we reached Sigiriya. We scaled the famed rock fortress—often nicknamed the Eighth Wonder—tracing weathered stairways to breathtaking panoramas. Nearby, the ruins of Polonnaruwa unfolded in quiet grandeur: crumbling temples and stone carvings whispering centuries of history. And at Minneriya National Park, a slow-moving wall of elephants transformed everything—suddenly the trip felt less like sightseeing and more like a profound encounter with the wild.

Gazing up at colossal Buddhas, wandering fragrant botanical gardens and watching hypnotic fire dancers set Kandy afire — then slipping into the misty charm of Nuwara Eliya, the “City of Light,” before plunging into Ella’s jungle-clad mountains, thunderous waterfalls and unforgettable train journeys.

We wrapped up our trip with a wildlife-packed morning at Yala National Park in Tissamaharama for close-up encounters with wild boar and elephant herds. Then it was on to the laid-back beach town of Mirissa, from where we explored the historic, lantern-lit streets of Galle, took a thrilling whale-watching voyage into the deep blue and lazy-afternooned on sun-drenched sands.

Get Your Whale On

Gliding out from Mirissa’s palm-fringed bay at dawn, you feel the ocean swell and the air tighten with anticipation as blue whales and playful spinner dolphins breach against a backdrop of glittering sea. Encounters are raw and humbling—close enough to hear exhalations and see towering tails, yet framed by responsible guides who prioritize the animals’ space.

Set Sail for an Unforgettable Whale Watching Adventure

Highly anticipated; a thrilling day of whale watching in the Indian Ocean with Raja & the Whales. Without issue, we were able to book an excursion and gather the necessary details the day prior. However, looking back we were quite lucky on timing. Still, if you have the time I’d recommend booking in person if that’s at all possible. If not, the company’s site offers a request form requiring 72 hours to confirm an online booking.

Tip / Whale watching isn’t a year‑round guarantee — seasons and stormy skies can send the giants (and tours) into hiding, so time your trip for the best chance of sightings.

Trips into the ocean run from November until the end of April or early May, as long as. there’s a minimum of 10 passengers, which is typically every day. Trips from August to October do occur if the weather and sea conditions are calm and there’s a minimum of 10 passengers. There are no trips in May, June and July due to monsoon season.

The first local company to offer dolphin and whale watching in Mirissa, Raja & the Whales is a local family business running tours nearly year round. By adhering to international whale watching regulations and providing valuable research data to international wildlife research and conservation organizations, Raja & the Whales sets itself apart, valuing the health and protection of whales over anything else.

If staying locally, jump into a tuk tuk just after sunrise and make your way to Raja & the Whales for check in. After the 6 a.m. check in, it’s time to wait patiently for others to arrive; there could be nearly 50 passengers in total. If you’re anxious about rough waters, make sure to request a few motion sickness pills (I was super happy I did). And finally, once everything is set, the guide for the day will lead the group to the boat, walking distance by foot.

Tip / If you get queasy on the waves, pop a motion-sickness pill before you set sail — your future self will thank you when the horizon stays beautiful, not blurry.

One by one, the group hops aboard, strapping into life jackets, as required. Almost immediately, staff offers a few snacks, as well as a modest hot breakfast.

They served coffee, huge plates of fruit including pineapple, banana, apple, passion fruit, pomegranate and mango, along with omelettes, sausage and toast (bread).

Tip / Bottled water and light snacks are available throughout the day but if you’re particular about tastes, pack your favorites. Don’t forget sunscreen, comfortable shoes and a camera to catch the best moments.

After about 45 minutes, it’s time to pull away from the dock and head out into the open ocean. During our trip, the skies were covered with a thick layer of morning fog and clouds but there was no rain in sight. The harbor was quiet other than a few fisherman beginning the day.

With hopes of seeing the largest creature on Earth and most common in this area, the boat will make its way out of the bay, passing all kinds of colorfully painted boats, manned by single gentlemen in clothing just as colorful. Besides potential blue whale sightings, other possibilities might include sea creatures like fin whales, sei whales, sperm whales, orcas (killer whales), pilot whales, humpback whales, dolphins, flying fish, turtles, manta rays and whale sharks.

If you’re lucky, large pods of dolphins can be seen speeding along swiftly, with grace and accuracy as they chase alongside the boat, zigging and zagging. Occasionally, they will burst out of the water and up into the air, silently splashing back down into the deep blue water. For me, this was truly an incredible moment to witness.

As time passes, large blue whales will begin to be spotted. Each time, the boat will wait, still and silent, bobbing up and down in the rhythmic ocean waters. Then, once the whale is spotted the boat will speed over as fast as possible in order to beat the other onlookers. Getting close but not too close, the boat pauses again and observes. We were even lucky enough to see a few of the whales blow air through their blowholes as they reached the surface to take a breath, as well as the random fin break the surface.

Our boat was careful not to get too close to the whales as to not disturb them. Still, we were able to see the shimmer of the whales back as it broke the waters surface and the flick of its tail as it dove back underwater. And though I was enjoying myself too much to take notes, we did learn that the more tail the whale shows, the deeper the dive. Additionally, throughout the tour, our guide made sure to give us many other interesting facts about whales.

The blue whales found in Sri Lankan waters are non-migratory and thought to be resident in the waters year-round. Far bigger than even the biggest dinosaur, the blue whale reaches nearly 100 feet long and 400,000 pounds, with a tongue weighing as much as an elephant and heart the size of a car. Honestly, I can’t wait for an opportunity to get in the water and swim with these magnificent giants one day.

Near the end of the excursion, cake is served, along with and juice and water. Expect the staff to be very kind, helpful and knowledgeable and after a few hours of whale watching it’ll be time to head back to shore.

I could’ve stayed out on the water for hours — and while I wished we’d seen the whales up close, I completely respect the strict rules that protect these magnificent animals. For my first whale-watching trip it was a magical experience nonetheless. And taking motion-sickness pills was the best decision; the sea was pretty choppy and a few people on board weren’t so lucky.

Bonus: Raja & the Whales will email you stunning photos from the outing the next day, so you’ll have great shots even if you missed the perfect moment.
