Apo Reef Natural Park has an area of 15,792 hectares including land and water areas. It was declared a protected area in 1996. A wonderful site for snorkeling and scuba diving, its crystal blue waters cover coral reefs teeming with a wide variety of marine life. The reef is home to 385 species of colorful marine fishes, including sharks, stingrays, mantas, tropical fish and morays, including the endangered Green Sea and Hawksbill turtles as well as 500 species of soft and branching types of hard corals. It also hosts 47 species of migratory and resident birds. Apo Reef has three islands, namely Apo Island , Apo Menor (Binangaan Is-land) and Cayos del Bajo, all with white beaches.
Apo Reef is almost untouched as is quite far away from the island of Mindoro. Due to its location in the Sulu Sea big fishes and whales are crossing Apo Reef frequently. Shark and tuna sightings are guaranteed on every dive and the chances of turtles, barracudas and schools of jacks are pretty high. If you are lucky you might also see the schools of dolphins and melon head whales on your way to or from Apo Reef. As the water is super clear and the visibility just amazing most of the time, Apo Reef is just as amazing for snorkelers.
The steep walls are well covered with corals, sponges, tunicates, nudibranchs and slugs. The coral formation at the plateau is magnificent. Green and hawksbill turtles, and a multitude of fish including damselfish, butterflyfish, batfish, surgeonfish, snappers, fusiliers and trevallies are common. Strong currents increase the chance of sighting sharks (hammerhead, blacktip, whitetip, grey and tresher sharks), great barracudas, tunas and manta rays.
