Sri Lanka’s coral reefs and shipwrecks offer rewarding underwater exploration for beginners and experienced divers alike. Pigeon Island National Park near Nilaveli and the reefs off Hikkaduwa and Trincomalee are among the island’s top snorkelling and diving sites. Warm, clear waters reveal colourful reef fish, turtles and, in Trincomalee’s case, historic World War II wreck sites. Guided sessions with certified instructors ensure a safe and enjoyable experience for all skill levels.
