Valley of the Rays dive site map, Yap Micronesia

Dominant features
Coral outcroppings rising from the sandy bottom of the channel serve as Manta cleaning stations. The Mantas hover over the coral heads & allow cleaner wrasse and other species of small reef fish to pick off parasites.
The center of the Valley is dominated by a huge formation of lettuce coral called the Merry-Go-Round which is the largest of the Manta Cleaning Stations. On the north side of the channel (Maap Side), another smaller formation of lettuce coral serves as another cleaning station called the Carwash. About 20 Meters east of the Carwash is Manta Rock, a large coral pinnacle that rises to within 33 ft. (10 M) of the surface and is the third cleaning station located in the Valley of the Rays. This tall outcropping also offers divers shelter from the current when the tide is strong.
This area is usually dove from moorings on the south side of the channel (Gagil Side). If the tide is slack, the boat stays at the mooring until you return. If the tide is running strongly, you begin the dive at the upcurrent mooring and exit at the downcurrent mooring to avoid a tiring swim. The current can be very strong here at times, especially near the outer cleaning station where the channel is slightly narrower and shallower. Make sure that you stay in the areas that the dive guides position you in. They will place you to get the best view without blocking the Manta’s approach to the cleaning station. Stay low, and avoid touching any of the live coral.

Beautiful variety of antler and table corals on the top edge of the channel. The center of the channel features a very large formation of lettuce coral.

Fish life
Mantas are the primary attraction at this site. They enter the channel in the morning to be cleaned after spending the night feeding in the open sea. When the tide is running, they will hover motionless over the cleaning station while small wrasse and other species pick parasites from their skin, and inside their mouths and gills. When the tide is slack, the Mantas slowly circle over the cleaning stations and allow the small fish to groom them. Sometimes several Mantas will be circling in a holding pattern much like airplanes at a busy airport. It is common to see several White Tip Sharks along the bottom of the channel. Large puffer fish frequent the sandy bottom of the channel. Octopi are sometimes seen both in the shallows at the edge of the channel and on the bottom near the outer cleaning station. While waiting for Mantas to show up, keep your eyes peeled because the channel is filled with all sorts of marine delights.

We stayed at the hotel and dove with Manta Ray divers in early December 2017. The hotel is very comfortable, well run and staffed with wonderful employees. During our visit my wife came down with an illness and the consideration and support from the hotel and dive staff could not have been more

The staff couldn't be more friendly and accommodating. Food is good, (worth upgrading to include all meals). Diving is good more

The best place to stay in Yap. The resort is really nice and clean, the scuba diving is great, and the docked ship that houses the bar, restaurant, and movie screen is very cool. I really enjoyed my stay more

Offers one of the best accommodation service. It also has a uniquely designed restaurant.

The whole place centers around the scuba diving operation. Probably better to find somewhere else if you're not a diver. The dive operation was generally good, but a little too laid back - schedules weren't always clear, and sometimes would change without any notice. Sometimes it was hard to tell if this was really because of changing tides/weather or because of the island pace of life. Pizza is a surprisingly good option at the more
