Manta Ray Diving in Yap

    A unique experience

  • Manta mating season is December - April and it offers the most frequent interactions with multiple animals and most behavior demonstrationated
  • Cleaning station diving is done year-round and it offers extended shallow dives with the mantas in close proximity, excellent for photography
  • Yap State is a Manta Trust field research site offering opportunities to participate in citizen science and join manta dive expedition trips
  • Mating season is Manta season - Yap has a year-round manta presence and as there are encounters throughout the year, the most consistent interactions with multiple animals and excitement is during their mating season
  • Manta Interaction Guaranteed Dive Packages Offered

Yap is gifted with it's manta ray presence - it's still one of the only places in the world where you have a great chance of diving with a manta ray any day of the year.

In the winter months the Manta diving is exciting, this is the time when you see small groups of rays and their courtship behavior, mantas dancing.

When you experience a mating train within arm's reach or mantas balling together in courtship, it's a "ten" for anyone's dive log.



Mantas are frequently seen on drift dives transiting channels and there's occasional outer reef deep blue water encounters. The most common and longest interactions happen at shallow cleaning stations where divers get buzzed by circling rays.

You can go manta diving every day here in small groups at sites inside the reef on calm water after short boat rides, just minutes from the hotel dock.

The manta presence is so strong that Yap State is a field research site for Manta Trust. Our rays are being identified, measured and indexed in a custom database for the conservation of all Micronesian manta rays.

How we do it

We make a dive to a cleaning station and remain stationary at the bottom, and the Mantas come to us.

The Mantas approach, more often than not two or three at a time, and hover at the cleaning station. The Cleaning Wrasse get into the action and nibble away at parasites in the gills and on the skin, getting a free meal while the Manta gets rid of uninvited and irritating guests.

The Mantas will be as close as a few feet from the divers, and the action often goes on for quite some time. The shallow depth and the divers remaining stationary at the cleaning station allows for extended dive times, a typical dive can last 55 to 75 minutes with several Mantas or groups of Mantas being "serviced" at arms length - cleaning station encounters are outstanding for photography. This is an experience that cannot be put in words.

Some simple rules for the dives:

  • We NEVER touch the mantas. They don't like it, and we respect that.
  • We don't use video lights.
  • Avoid hanging on to living coral. There's plenty of rock and dead coral.
  • Avoid blowing large bubbles under the mantas.

Wildlife Sanctuary Diving

Yap established manta ray protection with State Law 7-36 creating the world's first government-backed sanctuary.

Encounters with Yap mantas are personal experiences that typically happen right overhead.

Mantas feed, clean, mate (and are believed to give birth) in Yap's water year-round.
