Dive-site story
Hermance sits along the southern shore of Lake Geneva near the French border, serving as one of the region's most popular freshwater training and recreational dive locations. The site features an underwater trail marked with guidelines leading between small boat wrecks, training platforms, immersed statues, and sunken oddities. Divers descend over a shallow shelf that transitions into a silt slope dropping toward the deeper lake basin. Underwater navigation is aided by permanent guide ropes connecting the various submerged installations.
Extensive network of underwater guide lines connecting sunken boat wrecks and training platforms
Curated submerged attractions including statues and underwater art installations
Reliable encounters with predatory freshwater fish resting along the weed lines
