Sri Lanka’s southern waters between Mirissa and Dondra Head form one of the world’s most productive whale-watching corridors, lying directly along the migration route of the blue whale, the largest creature ever known to have lived on Earth. Ceyholiday’s whale and dolphin watching expeditions depart from Mirissa between November and April, when blue whales, sperm whales, Bryde’s whales, and large pods of spinner and bottlenose dolphins are regularly encountered in open water just a short distance from shore. On Sri Lanka’s east coast, the waters around Trincomalee offer excellent whale watching from May to October, providing a year-round opportunity to experience these marine encounters. All expeditions are conducted by responsible operators committed to internationally recognised whale watching guidelines, ensuring the welfare of the animals and the quality of the experience for every guest.
