Snorkelling on the coral reefs at Pigeon Island National Park  is absolutely fantastic wherever you are on the islands. But the main attraction is the island’s many juvenile and adult blacktip reef sharks. These sharks are up to five feet long and are reliably seen in an area next to the larger of the two islands, known as Shark Point Reef.

This nonaggressive species seems to be quite accepting of humans in the water, and snorkelers have an almost guaranteed opportunity to see them—sometimes as close as a couple meters away in water as shallow as a meter deep. It is one of the few places where totally inexperienced snorkelers can have as good a chance of a shark encounter as fully qualified scuba divers.

Pigeon Island National Park actually consists of two islands: large and small. It is a marine national park in Sri Lanka located in the general area of the city of Trincomalee and contains some of the best remaining coral reefs of Sri Lanka. Many of the 100 species of corals and 300 coral reef fishes recorded around the area are found in this national park. The coral reef is visited by Hawkesbill Turtle, Green Turtle and Olive Ridley Turtle and the island is important breeding ground for the rock pigeon. The area was badly affected by the Indian Ocean Tsunami in 2004 but has now largely recovered.
