Sri Lanka sits at the intersection of some of the world’s richest marine migration routes, making the waters off Mirissa and Trincomalee among the finest places to encounter blue whales – the largest creatures to have ever lived – in their natural ocean habitat. Between November and April, these gentle giants move through the Indian Ocean in extraordinary numbers, accompanied by pods of spinner dolphins that somersault joyfully alongside the boat. Our expertly guided boat expeditions are conducted in full compliance with responsible marine tourism guidelines, prioritising animal welfare while maximising your chances of an unhurried encounter with these creatures.
