This dive site, known as fosse Meyzieu, is primarily a purpose-built training facility located in Meyzieu, near Lyon. It features two distinct pits, one shallower at 6 meters and another deeper one stated to be 20 meters, though the site's overall maximum depth is 14 meters for general access. These pits provide a controlled and safe environment for divers to practice and develop their skills without the challenges of open water. The access is straightforward, located at 10 D rue Jean Jaurès, making it a convenient local spot for the diving community.
As a man-made training facility, the dive site does not boast a rich natural marine ecosystem. While some hardy freshwater aquatic plants or small fish might eventually inhabit the pits, divers should not expect to encounter diverse or abundant marine life. The focus here is on skill acquisition and gear testing rather than wildlife observation.
The best time to visit fosse Meyzieu is generally year-round, as its controlled nature means conditions are relatively stable, although water temperature will vary with the seasons, making appropriate thermal protection essential. It is particularly suitable for new divers, those undergoing certification, or experienced divers wishing to refresh skills or test new equipment. Both scuba divers and freedivers can benefit from the varied depths for practice. For freedivers, the 6-meter pit is excellent for introductory practice, while the 14-meter maximum depth allows for deeper breath-hold training.
