About this site
Deep Rock, locally Bogtong Bato, is a pinnacle in the northern part of Malapascua, Philippines, a tiny sunken island rising from the seabed at 28 m. The flat top is at 14 m, with sheer walls all around down to about 30 m and a slope on the south side. The walls are covered in colourful soft corals and feather stars.
Two large resident frogfish, ornate ghost pipefish and a huge variety of nudibranchs make it a favourite of macro photographers, with different shrimps and crabs as well. Strong currents can bring surprise encounters, such as the occasional school of trevally or barracuda. It suits Advanced Open Water divers, and Nitrox is a good choice here.
