1 / 8Snorkeling with Whales in Mirissa
About this activity
Swim alongside blue whales and sperm whales in their natural habitat off Mirissa's coast, a rare Sri Lankan marine experience where encounters vary daily based on whale behaviour and ocean conditions. This 4-hour boat excursion combines wildlife immersion with physical adventure, offering privileged access to one of the world's largest creatures in the Indian Ocean.
The opportunity to swim with whales is a privilege. The act of swimming with whales is an art. Every day is different on the water, and every encounter is unique. We swim with whales most days, but on some days this may only be briefly. Other days we swim for longer periods.
