Mirissa is famous for its sands and waves, but there's far more beneath the surface: an incredible array of sea mammals can be found off its coast. Join a whale and dolphin watching boat in seeking out some of the species that frequent Sri Lanka's waters and watch them swim and play in their natural habitat. Out in the waters, you might be able to spot the largest animal in the world: the blue whale. You may also see massive Bryde's whales, long sperm whales with their calves, spearlike Fin whales, and the intimidating Orca, or killer whales. The experience is a purely responsible one: you will not be disturbing the whales in their habitat and simply watch their pods swim along. This goes the same for the dolphins (among them common, bottlenose, spinner, striped, and Risso's dolphins) who will be playing and leaping from the water as they play in the bow waves. It's an unforgettable experience and a must-see for children!
