About this spot

Étang de la Carrière du Mont Juillet is a freshwater quarry dive in France that draws divers looking for an accessible site away from the ocean. The flooded quarry offers a unique environment different from typical coastal dives. Limited technical data is publicly available, but the site has attracted enough community interest to generate video documentation and species observations. Divers visiting this site should research current conditions beforehand, as quarry diving often involves sudden depth changes, unstable substrates, and variable water clarity. The year-round access makes it a solid option for off-season training or building cold-water experience in temperate freshwater. With three recorded species observations available through community contributions, the site hosts identifiable aquatic life worth documenting. Video content from visitors provides real-world insight into what to expect underwater. Check locally for any access restrictions or parking requirements before planning your dive trip.

  • "L'endroit ne figure sur aucune carte" : mon oeil ! Sur une carte IGN, on voit très bien ! Et même sur Google Map, c'est écris "la carrière" avec des photos ! Sur les vues satellites on peut pas louper ! Par contre c'est incroyable car à 300 m plus au nord il y a un lac légalement accessible ^^
