This is the east coast of Yap's answer to M'il Channel in the west. The resident population of mantas migrate here during the summer months of May-November and similar to its western counterpart, the overall area is split up into a number of different sites, all of which can be explored in one day.
The rays approach their cleaning stations via Goofnow Channel that has a sandy bottom at 17-25m. The coral outcrops here act as cleaning stations, the lergest of which - the Merry-Go-Round - is the biggest station on Yap.
To the north of the channel is The Car Wash which is a large lettuce coral formation and very closeby is Manta Rock, a coral formation that rises some 12m from the seabed and is a good spot to shelter from the currents and watch the rays as they arrive in the mornings.
