Gapow Reef - Yap
Gapow Reef is a solid Yap dive, often presenting mild currents that drift you along a healthy hard coral slope. We frequently spot reef sharks patrolling the deeper sections and smaller pelagics like jacks and barracuda schooling in the blue. It’s a good choice for divers looking for a relaxed drift and consistent fish action.
