Apo Reef Natural Park
Luzon Region
Apo Reef Natural Park, located off the coast of Occidental Mindoro in the Philippines, is the country's largest coral reef system and ranks as the world's second-largest contiguous coral reef. Covering approximately 34 square kilometers, the park features a roughly triangular coral atoll with two main lagoons separated by a deep channel. The reef system supports diverse marine life and is a renowned diving destination, drawing enthusiasts worldwide. The park includes three uninhabited islands: Apo Island, Apo Menor, and Cayos del Bajo, each characterized by unique geological and ecological features. Apo Island, the largest, hosts mangroves and beach vegetation and serves as the base for park rangers who enforce conservation efforts. Since 2007, a no-take-zone policy has been in place to protect the reef's fragile ecosystem. The park is also recognized as an Important Bird Area, supporting significant seabird populations. With limited facilities to preserve its natural state, Apo Reef offers visitors an immersive experience in marine biodiversity and conservation.
