Once an active asbestos mine, Carrière Flintkote now functions as a dynamic freshwater dive destination, its past operations creating a distinctive underwater landscape. Extending to an impressive maximum depth of 110 meters (360 feet), the quarry accommodates certifications from introductory to advanced technical training.
Industrial history is evident through scattered mining debris such as rails and old carts, contributing to the site's unique character. A primary entry point, known as "La descente," follows an old truck path, providing a gentle, sloping entry that aids in buoyancy control and depth management.
