Snorkelling is the best way to view underwater life in the shallow seas of Sri Lanka. The snorkelling gear can be bought or rented in the area. Almost every beachside shop has them. Snorkelling helps view the corals and shoals of fish without damaging them. You can also see the colorful live corals that live somewhat deeper. This is because even though the corals in the area are protected now the ones closer to the beach and surface have died out due human carelessness. It is important to note, though, that the shallow waters around Hikkaduwa can become quite crowded, especially during the peak tourist season. This can make it difficult to snorkel safely.
