About Le Tunnel de la Grande Vigie
Le Tunnel de la Grande Vigie is a summer-only arch-and-tunnel dive in Guadeloupe with a coral reef, dramatic rock structure, and a very specific sea-state window. The site feels more like a committed excursion than a casual splash, because the underwater architecture and conditions need to line up. Divers come for the arch, the tunnel, and the bright reef life that builds around the point. It is best treated as a guided boat dive for experienced divers who are happy to work around the weather.
