Situated in the Davao Gulf, east of Davao City, this island offers a multitude of sites to suit all tastes. To the northeast are Ligid Caves and Pinnancle Point. The caves are split into two at between 17-20m and there is a diverse range of coral and gorgonians. Smaller fish life is profuse, with the occasional sighting of sharks. Closeby, the pinnacle offers some exciting diving, but be careful as currents can be fierce. You can expect to come across octopus, morays, travally, surgeonfish and jacks.
Off the east coast, the most spectacular site is Pindawon Wall. Here, the overhangs house gorgonians and black corals with fish life including snapper, grouper and sea snakes. Both Pindawon and Aundanao, slightly to the north, are marine sanctuaries where there is every chance of seeing turtles.
Towards the south-eastern tip of the island, you'll find Mushroom Rock, so called because of shaped underwater rock formations. Expect to see large pelagics here, together with the occasional dolphin.
The west coast is best-known for the sites Marissa 1,2 and 3. These are all fairly shallow reefs that descend to 30m and offer good coral formations. Hawksbill turtles are regular visitors, together with pelagics and lobsters. Snorkelling is particularly good here.
