Amazing camping which was open but quiet when I visited in early May 2025 (tip - many French campings don't open until later in May). I would give this 10/10 even with the slight disturbance of the tranquilité caused by the construction of an enormous zip wire across the lake. The camping is located a long way from 'civilisation', at least by bike. However.... it has such great facilities, like a decently stocked and not expensive épicerie, incredibly clean loos and showers, decent self-catering (including amazing Office de Randonneur - an actual indoor kitchen which hikers and bikers are free to use. All this and a private (ish) viewpoint over the lake. Oh and a depot du pain and café service in the morning. Pretty much perfect
