Top Snorkeling & Diving Spots in Sri Lanka 🐠
1. Pigeon Island National Park – Trincomalee
One of the most famous marine parks in Sri Lanka, Pigeon Island is a must-visit. Shallow reefs make it a snorkeler’s paradise, while divers can venture further to see reef sharks and rays.
2. Hikkaduwa
Located on the south coast, Hikkaduwa is perfect for spotting turtles up close. The reef lies just offshore, so even beginners can enjoy a vibrant snorkeling experience. Divers can explore deeper sites with schools of parrotfish and moray eels.

This calm bay is excellent for families and first-timers. Divers can explore the historic Rangoon wreck from the 19th century, adding an extra thrill.
