S-pass drift dive with coral, current, and abundant lagoon life.
Passe en S #7 is an upright pass dive in Mayotte’s famous S-shaped channel, reached by a short boat ride from the main lagoon ports. The site is defined by drifting current, coral-rich structure, and the kind of wildlife that changes with tides, weather, and moon phase. It is a better fit for divers who are comfortable reading current and timing a drift-style boat dive than for anyone looking for still-water reef swimming.
