Scuba Diving in Sri Lanka – Reefs, Wrecks & Year-Round Adventures
From Unawatuna on the south coast to Trincomalee on the east, Pearl Divers takes you to Sri Lanka’s best dive sites.
Discover Diving in Sri Lanka
With its warm tropical waters, colourful coral reefs, and fascinating shipwrecks, Sri Lanka is one of the top diving destinations in Asia. The island offers year-round scuba diving, thanks to its unique monsoon patterns — when one coast is resting, the other comes alive.
At Pearl Divers, we operate two PADI 5-Star Diving Centres:
- Unawatuna (October–April) – calm south coast seas, historic wrecks, and vibrant coral gardens.
- Trincomalee (May–October) – crystal-clear east coast waters, dramatic rock formations, and pelagic encounters.
Whether you’re a complete beginner or an experienced diver, Sri Lanka has something unforgettable waiting beneath the surface.

Marine Life in Sri Lanka
Diving in Sri Lanka offers encounters with an incredible range of marine life. Both coasts are home to green and hawksbill turtles, schools of colourful reef fish, and larger species like Napoleon wrasse, groupers, and barracuda. Divers often spot moray eels, lionfish, and rays, while reef sharks add a thrill to some sites.
During the right seasons, Sri Lanka also becomes one of the best places in the world to see blue whales and sperm whales, with dolphins frequently spotted off Trincomalee. This biodiversity makes every dive a new and exciting experience.
