Camping Bois De Boulogne, Paris

Stayed here a few years ago now, but was really really busy in peak season, its the only campsite in Paris so loads of backpackers from all over Europe go there, so can be noisy. Toilet block was acceptable and was a shop/bar on site. The shuttle bus to the station doesnt run late at night and the trains stop running quite early back to the nearest station around midnight, so you cant stay in Paris too late in the evening. As you have to walk back to the site.

A very good campsite with access to Paris city. I've stayed here twice.
A shuttle bus gives access to Port Maillot metro station (Underground/Subway) for a nominal amount (7 Francs I think). The campground is reasonably priced, with good facilities and they sell very good roast chickens.
