Sri Lanka’s southern tip nudges the depths of the continental shelf. It’s an area favoured by blue whales and nowhere else does the world’s biggest creature swim so close to land, so reliably.
Dondra Head is your jumping off point. From January to April, blue whales pass here on their route from the Bay of Bengal to the western Indian Ocean. They fill their bellies on the krill and squid that thrive in these waters, enriched by the outfall of Sri Lanka’s 103 rivers.
