We have just returned from Camp du Pylone, Biot (near Antibes).
It was absolutely wonderful. We booked independently and the caravan was fantastic. The campsite has the most wonderful friendly feel. There is a swimming pool (small charge in July and August) plus a bar with nightly entertainment, restaurant and take-away and also the best bakery which is open all day.
It is situated right next to Antibes Land and the Marine Land complex, which is just fabulous. The train station (and bus stops) are about 3 mins walk from the camp entrance so a car is not needed at all.
Our children are 5 years and 18 months and we all had the best holiday. We have never returned to the same holiday destination as we always have felt there is more to explore but we all loved it so much that we are already booking for 2006. We haven't stayed in a caravan very often but were very impressed with the facilities. Try
