Yap State dive sites

Yes, Yap is one of the very few places in the world where resident reef manta rays can be observed every month of the year. The mantas shift between different channels with the seasons. From December to April, they concentrate in Mi'l Channel on the northern end of the island for mating, offering the chance to see a dozen or more on a single dive. During the rest of the year, they frequent the Goofnuw Channel on the eastern side.

The manta rays at Yap's cleaning stations are remarkably habituated to divers and will often approach within one to two metres of patient, motionless observers. Yap was designated the world's first manta ray sanctuary, and strict diving protocols require divers to stay low on the reef and never chase or touch the mantas. Following these guidelines virtually guarantees close encounters, as the animals recognize non-threatening behaviour.

Open Water certification is sufficient for most manta dives in Yap, as the cleaning stations sit at comfortable depths of 10-20 metres. The dives are relatively straightforward, though currents in the channels can pick up during tidal changes. Dive operators provide thorough briefings on manta etiquette and positioning, making this accessible to confident beginners as well as experienced divers.
