LE SOUS MARIN
Le Sous Marin: canyon dive near Saint-Pierre
Boat dives from Saint-Pierre reach canyons, caverns, and a tunnel; the site works best when swell stays down.
About LE SOUS MARIN
Le Sous Marin is a northern Martinique dive site near Saint-Pierre, known for its canyons, caverns, tunnels, and broken volcanic ledges. It is usually run as a guided boat dive, with the route unfolding through short swim lines, pockets, and openings rather than a flat reef track. Divers come for the varied relief and steady marine life, but the site is best left for calm seas because channel swell can make it impractical.
