Apo Reef: The Largest Coral Reef in the Philippines

Covering around 34 square kilometers, Apo Reef is the biggest coral reef in the Philippines and ranks as the world’s second-largest connected reef system after the Great Barrier Reef in Australia. It’s a massive, beautiful reef full of life and color, attracting nature lovers and divers from all over.

Two Reefs, One Unique System

Apo Reef consists of two distinct coral reefs separated by a 30-meter-deep channel. The channel’s crystal-clear waters are teeming with marine life, boasting around 285 species, including angelfish, butterflyfish, and sea turtles. It offers a rich and diverse environment for divers and snorkelers to explore.

A Diving Hotspot All Year Round

Renowned as one of the world’s premier diving destinations, Apo Reef attracts visitors throughout the year. Its soft, white sandy seabed and thriving coral formations are easily visible through the crystal-clear waters, creating an ideal setting for ocean enthusiasts.

A Protected Natural Park

Apo Reef and the waters around it are protected as part of the Apo Reef Natural Park, which sits roughly 33 kilometers off the coast of Sablayan in Occidental Mindoro. Established in 1996, it’s managed by the Philippines’ Department of Environment and Natural Resources (DENR) and is even on the list for potential UNESCO World Heritage status.

Islands to Explore Above the Water

Most of the reef lies beneath the surface, but three islands—Apo Island, Apo Menor, and Cayos del Bajo—rise above the water. These islands offer serene landscapes with untouched views, where the sounds of bird calls and gentle waves create a tranquil atmosphere. Visitors come to enjoy activities such as diving, snorkeling, bird-watching, kayaking, and occasionally spotting dolphins and sea turtles.
