This reef was completely destroyed by the El Nino that plagued the 1990s, but it has now completely recovered and is one of the best dive sites in Sri Lanka. This is largely due to the fact that in 1992, it was declared a marine protected area by the Government of Sri Lanka, as it is the largest ocean reef in Sri Lanka, and this allowed the marine life to flourish without interference from human action.
The reef is now home to 283 different species of fish and over 150 different species of coral. The reef is very shallow and dive boats need to be aware of this and navigate carefully. As the reef is so shallow, most visitors simply snorkel the reef. From May to November, it is not possible to dive or snorkel here due to the monsoon weather. The currents here are normally not that strong and as the reef is so shallow, divers should wear wetsuits to protect themselves and the corals, against accidentally touching the coral.
Like many of the other dive sites in the country, turtles are common in this site and divers can expect to see Hawksbill turtles, Green turtles, leatherback turtles, and other species of turtles. These will be alongside the many different types of reef fish, and it is very common to spot tuna and dolphins at this site.
