O'keef‘S Passage

This dive site features a stunning channel with strong currents, attracting large pelagic species like sharks and manta rays. The walls are covered in vibrant soft corals and sponges, creating a colorful underwater landscape. Visibility is excellent, often exceeding 30 meters. Divers can spot schools of barracuda and trevally cruising the current. The site is best suited for experienced divers due to the challenging conditions. The surrounding reef is teeming with smaller reef fish and occasional turtle sightings. The combination of marine life and dramatic topography makes it a must-dive location in Yap.
