The title should say it all. I have camped all over Europe and the UK and this place was the worst.
1. It is overpriced - It cost 31 Euros for one night (2 people, small tent, small car)
2. It is noisy - near a main road, gardeners start about 7am
3. There is little privacy from other tents
4. The toilets and showers are very dated
5. Lake Geneva isn't so good anyway - go to more interesting parts of Switzerland
Overall, I cannot recommend this campsite at all. Avoid
