Mantas visit Miil Channel on a daily basis between November and May. The channel is 90 to 100 feet deep with a ridge rising to about 33 feet. You can do a drift dive at the end of the incoming tide, then as the tide begins to change the Mantas appear. They will hover in the gentle current or sometimes perform sweeping loops at edge letting the tidal flow offer plankton from Yap’s rich mangrove. At slack tide the Mantas come to a cleaning station where small cleaner wrasse preen parasites from these majestic creatures. During the mating season from late December to April you can experience courtship rituals that give a new definition to Aquabatics.

Between June and October Mantas are likely to be seen in ´The Valley of the Rays´ also known by its Yapese name Goofnuw Channel. There are two cleaning stations in the Channel. The first station has a mound that rises to about 40'. Currents flow over the mound and surrounding coral heads providing a good feeding spot for the Mantas. A little further down the channel there is another cleaning station about 35' where a white sandy bottom makes for excellent photography.

Found on the Southern tip of the island Yap Caverns is a maze of caverns cut into the coral wall. Divers can enter large Chimneys adorned with hard and soft corals. Natural skylights illuminate the caverns. Marine life is abundant within the Caverns with large schools of pelagics including Tuna and Gray Reef Sharks patrolling the entrance.
