Projet X Aquapark, Cergy's water park and giant water slides, opens its doors!

Projet X Aquapark is the new water park opening its doors from June 14 to August 31, 2025. A giant 3,000 m2 aquapark, water slides and climbing walls, and a floating terrace are all on the program. With family or friends, it's the ideal spot to enjoy a cool summer vacation.

In the family of water parks, and in particular inflatable water parks, we call Projet X Aquapark, which awaits you on the Ile de loisirs de Cergy Pontoise in the 95 region of France.

For those of you who don't know, inflatable aquatic courses are floating structures on water made up of different workshops that allow you to have fun. To test your agility and balance, slide and bounce, this is the ideal spot for young and old alike.

Armed with a safety vest to keep you afloat whatever happens, you're ready to take on the Ninja Warrior course that awaits you. Nearly 3,000 m2 of inflatable play area awaits you. There's also a sensational X Tower with 9-metre-high slides, diving boards (6m, 7.50m, 9m), climbing wall and ventriglisse. Last but not least, there's a 300m2 floating terrace for a relaxing moment on the water.

Please note that Project X Aquapark is open to swimmers aged 6 and over. Children under 10 must be accompanied by an adult. Slides, diving and climbing walls are accessible from age 12. Departures are every 30 minutes (bookable or not). Remember to arrive 20 minutes before your time slot to suit up and listen to the safety briefing. Basically, we don't go under the structures, we avoid climbing behind anyone and we also avoid being too many on certain structures. Of course, water sports are supervised.

Projet X is open from June 14 to August 31, Monday to Sunday, 11am to 7pm. Don't forget to book your slots, they're going like hotcakes.

As the water park is located at the Cergy Pontoise leisure park, you'll also need to pay admission to the park, which offers a whole range of activities and a superb beach. Admission is €5 for all. Note also that if you're coming by car, you'll need to pay for parking between €5 and €7 from May to September, depending on the season.
