Racha Noi, Banana Rock is a boat-access island dive on the east side of Racha Noi, with a shallow coral-and-sand start that leads into larger boulders and deeper reef structure as you move away from the bay. It suits beginners and relaxed snorkelers on calm days, while still giving experienced divers a rewarding route that can drift south into Banana Bay or north into shallower boulder formations.
