About this site
This freshwater quarry in the Czech Republic offers clear visibility and submerged structures from its mining past. Depths reach 40 meters, with steep walls and platforms for exploration. Cold water attracts divers year-round, with occasional ice diving in winter. The site features old machinery and a sunken bus, creating an eerie artificial reef. Schools of perch and pike are common. Ideal for training and technical diving due to controlled conditions. No strong currents, making it accessible for various skill levels.
