Mirissa, Southern Province, Sri Lanka
The world’s largest mammal is surprisingly difficult to see – except here, on Sir Lanka’s southern coast. It’s the best, most accessible and most reliable place in the world to see – and snorkel – with the big blues. Tours depart from Galle and Mirissa between February and mid-March, when the whales feed on giant shoals of krill.
