Trincomalee is home to what is widely considered one of the finest natural deep-water harbours in the world and some of the most spectacular beaches in Asia. Nilaveli and Uppuveli beaches – long, tranquil stretches of sand and calm blue sea – rival any destination in the region for sheer beauty. The area is ideal for snorkelling and diving, particularly around Pigeon Island National Park, where reef sharks, sea turtles and vibrant corals are regularly encountered.
