This dive site, Le Tunnel de la Grande Vigie, is an exceptional underwater experience located north of Grande-Terre, Guadeloupe. Accessible approximately 40 minutes by boat from Port-Louis, the dive is only possible between June and October under very specific conditions, indicating the importance of timing and weather. The site is characterized by a superb arch and a dramatic 20-meter-long tunnel, offering a unique navigate-through experience for divers.
The marine life here is abundant and diverse, showcasing vibrant ecosystems. Divers can expect to encounter an array of creatures including lobsters, various sponges, and multicolored corals that adorn the reef. Among the fish, barracudas, angelfish, and jacks are commonly sighted, alongside smaller inhabitants like shrimp and spider crabs. Occasionally, lucky divers might even spot dolphins in the vicinity.
The best time to visit this site is specifically between June and October, when conditions permit safe diving. Divers should be well-prepared for varying conditions and possess good buoyancy control, especially for navigating the tunnel. For freedivers, the site offers an excellent opportunity to explore the arch and tunnel at depths well within freediving range, provided conditions are calm. It's a prime location for wide-angle photography due to its stunning geological features.
