Sri Lanka’s coastal waters support rich marine life – from the coral reefs and reef sharks of Pigeon Island in Trincomalee, to the sea turtle feeding grounds along the south and east coasts, accessible to non-swimmers and children at the right calm-water locations. The Guardian Holidays arranges snorkelling excursions at the most appropriate locations for each traveller, selected based on current conditions, water clarity and the marine species most likely to be encountered.
