This is another fantastic dive site in the Tubbataha region, and part of the Tubbataha Reef Marine Park, which is itself a UNESCO World Heritage site. The site is well known for having very high numbers of marine species and an unusual topography and is often said to be the best diving to be found in the Philippines.

The site is made up of a coral reef that has perpendicular walls, two coral atolls, and quite large lagoons. Currents can be very strong and so only experienced divers should attempt this dive. The plateau of the reef slopes down from around 15 metres to around 25 metres in depth. The island is very far from any other land mass and this means that there is no silt runoff and so great visibility. Visibility can sometimes be further than 50 metres. Most diving is also done during the dry season, and as all divers learn, no rain means greater visibility.

Black rock as great coral that is made up of many different soft and hard corals. At the beginning of the dive, divers often encounter two titan triggerfish. Along the seabed, it is very common to see nurse sharks, white tip reef sharks, and grey reef sharks resting, and out in the open divers can normally spot guitar sharks, leopard sharks, and hammerhead sharks. Other common large fish include large schools of tunas, barracudas, surgeonfish, sweetlips, rainbow runners, and jacks. Around full or new moon, it is almost guaranteed that manta rays will be spotted. Eagle rays and turtles are also frequent visitors to the site and it is a great place to try to spot lobsters.
