This dive site is Carriere de la Rochefontaine, an old red marble quarry in Belgium that was actively exploited until the 1980s. Underwater navigation begins with an oblique plane gently descending from a depth of 4 to 6 meters, with this initial depth varying seasonally. Beyond this entry point, the quarry's unique topography is characterized by dramatic steep walls and a series of distinct plateaus found at depths of 22m, 26m, 36m, 40m, 43m, and 52m, although the maximum recreational dive site depth is specified as 33 meters.
The resident aquatic life within this red marble quarry includes a variety of freshwater species. Divers can observe carp, roach, and perch swimming amongst the structures. For those with a keen eye for smaller inhabitants, crayfish and small newts can also be spotted, particularly in crevices and along the quarry floor.
While the information doesn't specify a "best time to visit," quarries like Rochefontaine often offer consistent diving conditions year-round, with potentially better visibility during colder months due to less algal bloom. For divers, understanding the multi-level profile and managing depth, especially around the steep walls and deeper plateaus, is crucial. Freedivers will appreciate the significant depth range available for training and exploration, particularly the deeper sections. Divers should be prepared for cold water, common in Belgian quarries.
