The boat eases away from the marina and the mainland melts into a low horizon of palms and corrugated seawalls. Minutes later the captain eases up onto a shallow shelf where crystalline water catches the sun and the sandbar appears like a bright stage. Guests disembark into waist‑deep water: the sea nudges and invites rather than demands — a perfect place to float, wade, or slip on a snorkel mask.
