Sannois Beach: water games, sports, and free activities this summer 2026 in the Val-d'Oise

Throughout July, the town of Sannois transforms into a free-leisure hub, with water play areas and sports facilities, giving this corner of the Val d’Oise a holiday vibe. A wide array of activities for the whole family awaits you this summer!

For the first time, the town of Sannois is launching its new event Sannois Plage. From July 4 to 31, 2026, the Jean Mermoz square and the Jean-Claude Bouttier sports palace will welcome residents for a program of summer and aquatic activities. Open from Wednesday to Sunday, 2 p.m. to 8 p.m., these two sites offer free activities for all ages.

Jean Mermoz Square centers on leisure and refreshment activities. Visitors will find an aquatic platform, a belly slide structure, as well as spaces for sporty play with equipment on loan. Wednesdays are specifically devoted to activities aimed at young people.

At the Jean-Claude Bouttier Sports Palace, the offering leans toward sport and larger-scale facilities. The site features multisport courts, a space for beach-volley and a toboggan aquatique, accessible from age 6 when accompanied by an adult.

While access to these facilities is completely free, certain activities impose logistical constraints on users. For the “fun bike” sessions or the “roller dance” (roller dance), wearing a helmet is mandatory and protective gear is not provided on site. Participants must bring their own helmet to be allowed on the tracks.
