Arche et Tunnel de la Vigie

The Arche et Tunnel de la Vigie sits on the northernmost cliffs of Grande-Terre, roughly 40 minutes by boat from the Port-Louis harbour. The site features an underwater arch and a long tunnel that cuts through the rock, both running inside 25 metres of depth. Dives happen in Caribbean waters on the west face of the cape, but the site's exposure to north swell means access is only practical from June to October. Typically managed via waitlist given demand. Advanced Open Water preferred.
