The Rip is a fast-moving drift snorkel at the southern tip of Direction Island in the Cocos (Keeling) Islands. It suits confident swimmers who want a narrow channel ride past coral gardens, reef fish and shark habitat, with scuba only when the lagoon flow eases enough for a controlled drift. Expect a seaward-to-lagoon run, fast-changing current, and timing that depends on tide, swell and moon phase.
