The boat slips away from the marina at Bas‑du‑Fort just after dawn, the lagoon opening like a shallow, warm room around you. Salt air pushes at the bow, and mangrove trunks lean in as if listening; the captain points toward a low coral barrier and the pale crescent of a sand islet where you’ll stop with feet in the water.
