Tubbataha Reefs Natural Park, a UNESCO World Heritage Site in the heart of the Sulu Sea, is accessible only by liveaboard during a narrow March-to-June season. Its 97,000 hectares of protected reef support hammerhead schools, whale sharks, and some of the healthiest coral in Southeast Asia. The remoteness is part of the appeal — this is diving at its most wild and unspoiled.
