Diving in Sri Lanka offers an unparalleled opportunity to explore vibrant coral reefs, historic shipwrecks, and diverse marine life. With its warm waters and rich underwater ecosystems, the island is a haven for both novice and experienced divers.
The ocean around Sri Lanka whispers of tales bygone, ones of regal maritime visits, of bandits and pirates and journeys of explorers and spice merchants. As you plunge into the warm waters and dive below, these stories come to life. The crystal clear waters of the Indian Ocean with a visibility of 20 meters (65ft) provide perfect conditions for diving. With wrecks as dated as the 18th Century dotting the seas, deep reefs and reef walls provide enthralling explorations for scuba divers. For the less adventurous on-shore coral reefs are ideal for snorkelling. The abundant marine life found around the island is surpassed only at Hikkaduwa in the southern coast where the reef is thought to contain more species of fish than the Great Barrier Reef.
