The pristine reefs of the marine sanctuary at Apo Reef offer a sanctuary for divers in the small reef system of Mindoro Island. Both pelagic and macro life are present in this stunning location.

The world-renowned wrecks of World War II at Coron north of Palawan are a wreck diver’s paradise. The protected waters of the bay offer access to these submerged vessels which are within recreational limits for advanced divers.
