The practical picture

Sri Lanka is one of the best places on earth to see blue whales, with Mirissa the launch point from roughly November to April and Trincomalee taking over in the east-coast season. The privilege comes with rules: boats must stay 100 metres from whales, approach in parallel and never box an animal in.

Choose an operator that advertises the guidelines, caps passenger numbers and refuses the illegal swim-with-whales offers still floating around. Go on a calm early-morning departure, take the seasickness tablet an hour before, and let the ocean provide.
