Best for intermediate divers, 6-40m, shore entry, moderate current.
Yap Caverns is a shore-entry site featuring a complex topography of reefs, canyons, and walls that descend to 40 metres. The site is defined by its cavern and canyon structures, which lead to a significant drop-off. Divers should expect moderate currents and variable visibility ranging from 6 to 60 metres. Due to the presence of surf and a shore break, careful timing of entry and exit is required. The site is suitable for intermediate divers who possess solid buoyancy control. Water temperatures remain stable between 28 and 30 degrees Celsius. Night diving is available, and the varied terrain offers a different experience with each visit.
