The waters off Sri Lanka’s southern and northwestern coastlines offer some of the most spectacular marine wildlife encounters on the planet, with blue whales, the largest creatures ever to have lived on Earth, migrating through these rich, warm seas between November and April. Our whale watching excursions depart from Mirissa aboard comfortable, responsible-tourism-certified vessels with experienced marine naturalists who guide you through each sighting with knowledge, care and respect for the animals. Spinner dolphins frequently join boats in the bow wave, and sperm whales, Bryde’s whales and occasionally orcas are also sighted in these waters.
