Punta Sur is Cozumel’s southern wall-and-passage dive, built around the Cathedral cavern and the famous Devil’s Throat. It is a boat-based advanced drift dive where the terrain, current, and the captain’s weather call shape the day more than simple convenience does. The reef is a history of steep walls, coral mounds, and long swim-throughs, so the best dives are the ones that keep the pace calm and the plan disciplined. This is one of the island’s signature dives because it combines dramatic topography, strong water movement, and the kind of visibility that makes the structure read cleanly in the blue.
