This excellent reef near the north-shore of Culion Island slopes from 3m down to 35m+.
It usually offers a quite good visibility of 15-20m. The best parts are the shallow ones with a plenty of different species of hard and soft corals and a rich fish life, including the common reef-fishes like anemone-fishes, batfishes, moray-eels, puffers, etc. Turtles and the giant clams are common; with good luck you can encounter a leopard-shark and guitar-shark.
It is possible to combine this dive with one of the wrecks in Coron-Bay.
