Remote Philippine atoll walls and seamounts, best explored by expedition or liveaboard
Overview
Apo Reef Natural Park is a remote atoll system in the Mindoro Strait, about 30 km to 40 km west of Mindoro and 28 km to 33 km offshore from Sablayan, Occidental Mindoro. Protected as a Natural Park with surrounding waters as a buffer zone, it includes Apo Island, Apo Menor (Binanggaan), and Cayos del Bajo (Tinankapan), plus a shallow lagoon and current-swept outer walls.
Most visitors come on multi-day expeditions from Sablayan or by liveaboard on routes that often pair Apo Reef with Coron. Underwater, expect drift dives along walls like Shark Ridge, deep seamounts like Apo 29, and a real chance of sharks, schooling barracuda, turtles, and big reef fish. Topside, you can camp on Apo Island and hike to the lighthouse for panoramic views.
This is a destination for divers who want frontier-style reef action with serious conservation credentials.
