This area is found right on the southern tip of Mindanao and the main site, Tambuan (Tinoto) Wall is approximately a 45 min road journey from General Santos itself. The wall stretches for 10km and reportedly drops to 200m.
There are some 20 small sites that are regularly visited in this area and all have their own characteristics. Overall, the wall is an experience not to be missed, but due to strong currents, only the advanced should attempt the dive.
Corals are everywhere, supporting a wide variety of smaller fish life. Further out you enter the domain of whitetip, blacktip and hammerhead sharks. Manta and eagle rays are often present as are Napoleon wrasse, tuna, barracuda and snapper.
Closer inshore, at shallower depths which extend some 50m offshore, the snorkelling is good.
Another site worthy of mention is Maharlika Beach Resort. This is a shallow reef with lots of attractions. Staghorn corals are profuse and home to sweetlips, wrasse, groupers, moorish idols and many more. There is a resident shoal of yellowtail barracuda and the area is a breeding ground for squid between June and July. Additionally, the resort is renowned for training and night dives.
