    StandoutExceptional marine biodiversity

    Manta Ridge in Yap is exactly what it sounds like. We’ve found ourselves finning along a coral ridge, usually around 10-15 meters, watching manta rays glide past. It’s a reliable spot for encounters, particularly on incoming tides when they come to feed and visit cleaning stations. Currents can be strong, so it’s best for confident divers comfortable in moving water.
