Jablines is a modern site which, with the leisure facilities of the adjacent Espace Loisirs, offers an interesting alternative to other sites in the region. Man-made lakes provide opportunities for many water-based activities. The Grand Lac is said to have the largest beach on the Ile-de-France. The site itself has 154 pitches, of which 143 are for touring units. Most are of a good size (100-120 sq.m), often slightly sloping, with gravel hardstanding and grass, accessed by tarmac roads and marked by young trees. All have 10A electrical connections; 60 are fully serviced. There are 11 wooden chalets to rent.
The whole complex close to the Marne has been developed around old gravel workings. Whilst staying on the campsite admission to the Base de Loisirs is free. Water activities include catamaran sailing, windsurfing, water boarding, canoeing, fishing and supervised bathing, plus a large equestrian centre, an orienteering course, a multisports court and mountain bike trails. In high season, the activities at the leisure complex are supplemented by a bar/restaurant and a range of very French-style group activities.
