Key Dive Site Facts
Dive Site Overview
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.
Annually, the quarry attracts over 2,000 divers, many traveling from outside the immediate Thetford region, with Canadian Marine members also utilizing it for maintaining ice diving competencies during colder months. Intentionally submerged objects, including a plane, a helicopter, a sailboat, and various works of art, alongside more unusual items like a kitchen, enhance the dive experience.
Submerged features create compelling navigation points, transforming the industrial legacy into an engaging underwater environment for exploration at multiple depth levels.
