Gentle shore dive on Lake Bourget.
Charpignat is a Lake Bourget shore dive at Le Bourget-du-Lac, entered from steps near the parking area. The first section is gentle and easy to read, which makes the site useful for training and relaxed exploration. A small rowboat sits outside the harbor channel as a landmark, and the profile then deepens into a more interesting freshwater site for divers who want a compact route with a clear start and finish. Planning is simple, but the lake can still shift with wind, boat movement, and seasonal clarity.
