Manta Scramble, Ishigaki Island Overview

A cleaning station off Kabira Ishizaki where reef mantas queue above the coral heads to have parasites picked off, which is why they hover instead of passing through. The season runs April to November and peaks July to September. The Yaeyama diving association enforces a fixed approach route and a no-chasing rule, so boats take turns and you wait your slot rather than swimming toward them.
