Overview

Remote Philippine atoll walls and seamounts, best explored by expedition or liveaboard

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.

What Makes It Special

  • Protected Natural Park

    Declared a protected area (Natural Park) with surrounding waters as a buffer zone, administered by DENR and the Protected Area Management Board.

  • Atoll scale, rare in the region

    A vast reef system with lagoons, walls, and offshore seamounts. The reef area is often cited around 34 to 40 square kilometers, making it the Philippines' largest contiguous reef.

  • Big-fish drift diving

    Current-swept walls and pinnacles attract reef sharks, barracuda, jacks, tuna, and occasional larger pelagics.

  • Gateway flexibility

    Dive it as a Sablayan expedition or via liveaboard routes departing from Batangas (Luzon) or Puerto Princesa (Palawan), often combined with Coron.
