Diving Destinations in Sri Lanka
Explore the most incredible underwater destinations in Sri Lanka. From tropical reefs to dramatic walls, discover your next diving adventure.
Mirissa
Mirissa is a mellow fishing town on Sri Lanka’s south coast that doubles as a great base for easy reef diving. Its sheltered bay leads to a string of near‑shore sites where coral bommies and sandy patches host hawksbill turtles, oriental sweetlips, triggerfish and schools of fusiliers. Macro critters such as nudibranchs, octopus and pipefish hide among the rocks, while seasonal plankton blooms occasionally attract whale sharks. Calm conditions and shallow depths make Mirissa perfect for beginners and casual divers looking for warm, colourful waters without the crowds.
Trincomalee
Trincomalee sits on Sri Lanka’s eastern coast and is famous for its sheltered natural harbour and nearby coral reefs. The region offers a mix of shallow fringing reefs, dramatic drop‑offs and historic wrecks like the HMS Hermes, the world’s first purpose‑built aircraft carrier. Pigeon Island Marine Park protects vibrant coral gardens where blacktip reef sharks patrol and hawksbill turtles graze, while Swami Rock’s vertical wall teems with reef fish and soft corals. During the calm months the waters are crystal clear, and blue and sperm whales cruise just offshore, adding to Trincomalee’s appeal as an emerging dive destination.
