Coral reefs off Pigeon Island, Hikkaduwa and the Kalpitiya peninsula offer accessible snorkelling and diving for all experience levels. Warm, clear waters support reef fish and turtles, and, in the right season, reef sharks, alongside several well-preserved wreck dives for certified divers. Kalpitiya’s offshore reefs and Trincomalee’s Pigeon Island National Park are particular highlights, each best visited in its respective calm-water season. Equipment, instruction and guided trips can all be arranged locally, including short introductory dives for first-timers.
