We camped here for 2 weeks (19 to 31 August). Medium-sized site. Pitches average size marked out with 2-3 posts / low hedges / straggly bushes. Site has mobile homes, seasonal pitches, canvas bungalows and regular touring pitches. Campsite has own entrance to beach on Lake Geneva with lifeguards.
The beach is a public beach with a car park, ice cream kiosk, small cafe. Lake very safe for children as the slope is very gentle (100 yards out and water still not waist high for adults). You could swim / boat / windsurf / pedalo. On the lake.
The scenery is stunning with Switzerland visible straight ahead and the Alps surrounding you. Small campsite shop with anything you might need, including camping gaz and fresh bread every day (bread from supermarkets/ bakers tasted nicer, though). Reception very helpful.
We were the only British on the site during our stay apart from a couple of overnighters or 2-3 dayers. Many large hypermarkets / Decathlon within 1/2 hour's drive from site. There was also a laundrette right by the site entrance. The site has no bar, but there was a lovely restaurant / brasserie right next door.
When we turned up, reception gave us a pitch (asked us if we'd like to be near lake), but said if we didn't like the look of the pitch to come back to reception and they'd give us a different one. They also gave us a recycling bag on which everything that could be recycled was clearly marked. Only downside was that the only bins (including recycling) were sited all together near the site entrance (we were a bit of a walk from there, being near the lake). We had not booked, but think we were lucky to get a pitch, as the site is obviously extremely popular.
During second week, site was obviously starting to close down for the season as one-half of each washblock was shut. Washblocks were mixed. Each block was slightly different. Each had loos (French and English), showers and wash basins, but some had enclosed wash basins. Showers are push button and free, but water temperature could not be regulated. Each block also had electric sockets. The drinking water tap and the chemical waste were a bit of a trek, but that didn't bother us.
Ground was earth and sand with bits of grass. After1 1/2 days of thunderstorms (only bad weather we had) we realised why everyone else had tarpaulins along the front of their tents / awnings. The front of our awning got very dirty from the ground being splattered against it by the rain!
There aren't any very large towns near this site, apart from Geneva, but you can get anything you might need as the surrounding towns, although small, seem well served by shops and supermarkets. We saw hardly any other Brits at all, apart from when we went to Chamonix for the day.
We would definitely stay here again and this site comes highly recommended by us. The only reason we won't be going back next year is that we want to explore more of France. This site will take a lot of living up to.
