My experience at the Manta RayBay Resort was once in a life time. We did not dive because we were in Yap for military purposes but if I had to choose a location in which to dive it would be in Yap and I would stay at the Manta Ray Bay Resort again. Bill and his family are just wonderful and made our experience on Yap such a memorable one. I hope to come back to Yap again and if I am so privileged I would visit with my adopted family and stay at the Manta Ray Bay Resort again.read more

Completed my 7th trip to Yap this past April and it is still one of the best dive destinations and operations around. Have led groups there for those 7 years and had several repeat customers go back with me. Great staff, dive operation and beautiful hotel. And the diving is diverse and just awesome. Many of the staff have become friends and it always a treat to be greeted by name upon arrival and around the hotel. Since diving is the premier attraction the island is a paradise of relaxation and laid back attitude. If you haven't been to this area of the world you should really consider it. Bill Acker, owner and all around good guy, can help you make travel plans for visiting Yap and other great destinations in Micronesia.read more

Beautiful resort and location, small and quaint with very attentive service from wonderful staff who were extremely friendly and helpful, and knew everyone's name (travelled with a group of 20 people) within the first day. Yap Divers staff were amazing, we were even offered hot tea during our surface intervals with some delicious snacks, and they ensured we had the best possible dive experience on each dive. I would return to this gorgeous island and absolutely stay at Manta Bay Resort again, it's well worth the trip!read more

MantaRayBay Resort, is THE dive resort. It is so obvious that this place was designed for divers, BY divers. The concept that all of the guests are part of the resort family seems to be the cornerstone of MRB Resort. The dive service is top notch; the wait staff spot-on, the resort staff super friendly and attentive. The dive sites are great, especially the southern walls, and of course the cleaning stations visited so often by the Manta Rays. I have gone scuba diving all over western Asia and the Caribbean, and MRB Resort is at the top!read more

We were from 11.08 to 18.08 at the Manta Ray Bay resort and had unforgettable days there 😍In total we made 12 dives with wonderful encounters. Highlights were, of course, the manta rays in the Goofnuw Channel and many white tip reef sharks in the Shark City 🦈 But also we saw eagle rays, turtles 🐢 and buffalo head parrotfish. The hotel is beautiful and the whole team does a great job there. The food on the ship Mnuw, as well as the home-brewed beer are excellent. Thank you again to the whole team of Manta Ray Bay Resort and Yap Divers 👏🏼We also did a one-day land tour to explore the many beautiful places of this unique island. The beach is like in paradise🏝, stone money and relics from the second world war very worth to see! You find there also culturally typical houses with different meaning and use! It would be nice if more visitors would come to this great island and appreciate the great work that is done there! Anyway, we really enjoyed it and would come back anytime 🙏🏻✌🏼read more

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 restaurant.read more
