Our House Reef Variety of corals, nudibranchs and fishes, good for macro photography. a small fishing boat wreck can be found at about 18 meters / 60 feet Cathedral Marine Park Sanctuary Approximately 23 meters/76 feet off Bagalangit Point lies a giant rock formation that looks a roofless underwater amphitheater. Originally barren, the Cathedral has been seeded with corals. Moorish idols, parrot fish, and the usual reef dwellers all cluster around divers and peer into their masks. Sombrero Island On the surface, this island resembles a hat underwater, so its profile makes the name Sombrero even more appropriate. The rim of the “hat” stretches a long way underwater from north to south. Gorgonians, black coral, shells, turtles, rays, grunts, jacks, snappers and great variety of soft corals are scattered all over the place. Currents are normally strong during the full moon.
