Set out from Mirissa harbour at dawn for one of the most extraordinary marine wildlife encounters on earth – a guided expedition in search of blue whales, the largest animals to have ever lived, in the rich deep-water channel that runs off Sri Lanka’s southern tip. Operating from November through April, our Mirissa whale watching excursions give you the best possible opportunity to witness these magnificent ocean giants, which can reach up to 30 metres in length, surfacing, breathing and diving in their natural habitat. Alongside blue whales, the waters regularly produce sightings of sperm whales, Bryde’s whales, pods of acrobatic spinner dolphins and flying fish leaping in the boat’s wake. The experience is led by knowledgeable marine guides who provide context and care throughout, making this both an exhilarating adventure and a genuinely educational encounter with the ocean’s most magnificent inhabitants.
