Sri Lankan Blue Whale Expedition

Swim with the biggest animal that has ever lived!

A rare opportunity to swim with the largest animal in the world

In March and April each year, blue whales migrate through the warm, clear coastal waters of Sri Lanka. When this incredible event occurs, we are there to meet them.

To get close to the whales without them getting stressed, we use small fast chase boats that hold a maximum of 4 free divers. With the help of expert guides, we will put you right in the path of the largest animal that has ever lived, observing the whales as they feed, swim and socialize.

Imagine this encounter

You slip into the water in front of a behemoth and float quietly above it or free-dive down to its eye-level as it glides past. You feel like an insect next to its unimaginable bulk. Perhaps you see a glimmer of recognition; a slight flick of its eye in your direction. Then, the whale mysteriously dissolves back into the deep blue void, surfacing 10-12 minutes later for another few breaths before diving again.

A chance to swim with an amazing selection of other cetaceans

The focus of this trip is encounters with blue whales but they are not the only cetaceans that call Sri Lanka home. During your Whale and Dolphin snorkeling safari, you may have the opportunity to snorkel with up to thirteen species of whales and eight species of dolphin, including sperm whales, humpback whales, beaked whales, melon headed whales, pilot whales, and false killer whales.

Sperm whales can sometimes be seen in extremely large aggregations.

Other than blue whales, the most commonly seen cetaceans are Sperm Whales, Brydes Whales, Short Fin Pilot Whales, Spinner Dolphins, Humpback Dolphins and Bottlenose Dolphins.

Leave your dive gear at home

Blue whales and other Sri Lankan cetaceans may be enormous but they are also very shy animals. Noisy scuba equipment would frighten the whales into a deep dive so it is far better if we take a minimalist approach.

This encounter requires nothing more than a mask, snorkel and fins. The most effective way to get as close as possible to the whales is to judge their direction of travel, slip into the water and float at the surface in their path.

Stay in paradise

During your Sri Lankan Whale Adventure, your home away from home will be the luxury Trinco Blu Resort Hotel in Trincomali.
