The largest contiguous coral reef in the Philippines and the second-largest in the world — an isolated 34-square-kilometre atoll of coral, lagoon, and mangrove in the Mindoro Strait, teeming with sharks, turtles, and rays.
A pristine, remote atoll system in the middle of the Sulu Sea — nearly 100,000 hectares of coral reef, sheer walls, and open ocean that rank among the healthiest marine ecosystems on the planet.
