Dive-site story
Cathedral Cavern penetrates the limestone karst on the southern side of Coron Island. Divers descend along the reef wall before entering a submerged tunnel that opens into an expansive interior chamber. Inside, natural light filters through openings in the ceiling, illuminating ancient stalactites where divers can safely surface into the cavern air space.

Opportunity to surface inside an enclosed rock dome surrounded by hanging stalactites
