This dive site, Pierre à Bise, located in France, offers a challenging yet rewarding shore dive experience. Access is provided via steps, though divers should be cautious as the entry into the water can be slippery. The site descends steeply from the entry point, forming a wall-like topography that quickly reaches its maximum explored depth of 45 meters, with the actual bottom extending beyond 60 meters.
Marine life primarily consists of various perch species. Divers can expect to encounter Sun perches and common perches, particularly visible among the shallow seagrass beds near the entry point. The background of the dive site is often described as black, yet the fish life remains visible against it, creating a unique visual experience.
While no specific best time to visit is provided, lake diving in France is generally pleasant during summer and early autumn when water temperatures are milder. Visibility can be poor in the first 0-10 meters, but significantly improves with depth, offering clearer views of the deeper wall and its inhabitants. Advanced divers comfortable with deep profiles and potentially low initial visibility will find this site most appealing, and caution should always be exercised during the slippery entry.
