This dive site, located at the Port of Lac de Nantua in France, offers a unique freshwater diving experience. Divers access the site via steps or a pontoon, descending rapidly into the lake's depths. A major attraction is a captivating aircraft wreck, visible at around 27 meters, adding a fascinating historical element to the otherwise dark and muddy environment. The site's rapid depth gain and dim conditions necessitate good buoyancy control and navigation skills.
In terms of marine life, the lake is home to common perch, often seen in the shallower areas and sometimes even near the sunken aircraft. Divers may also encounter pike and 'plate' (likely bream or similar flat-bodied fish). The ecosystem is adapted to the colder, darker conditions of the deep lake.
Visibility in shallow water can be variable depending on the season, but generally improves once below 10 meters. However, the site becomes significantly dark, even black, at greater depths, necessitating good dive lights. This site is particularly suited for experienced divers comfortable with deep, dark, and potentially cold conditions. Freedivers could explore the shallower sections and the initial descent, while snorkelers can enjoy the surface areas where common perch are often found.
