Mi'l Channel
Yap's classic winter manta site: a channel with a sandy rubble floor and vertical coral walls, crossed by Manta Ridge, a coral ridge that speeds the tide and creates a cleaning station. On an incoming tide it is a drift down the middle of the channel; mantas mate here from about December to April, and turtles, reef sharks, eagle rays and schools of jacks pass along the outer side. Current is barely perceptible at slack tide but can run up to about 6 km/h.
