Passe en S #1B is a shallow pass dive with turtles and coral.
Passe en S #1B is a shallow mooring on Mayotte's famous S-shaped pass, where coral structure rises from the drop-off and turtles and batfish often cruise the calmer sections. The exact spot is chosen around wind and current, so it works best as a guided boat dive rather than a fixed route. Its appeal is the sheltered bends and easy topography, not a hard technical profile.

Scuba Diving
Guided scuba dives use the pass's moorings and can range from shallow coral steps to faster-moving sections, depending on conditions.
Freediving
The shallow top can suit experienced freedivers on calm days, but only with guide direction and current awareness.
Snorkeling
The shallow top can work for calm-day snorkeling, but the pass is mainly a guided boat dive because of currents and boat movement.
