Île de loisirs de Jablines-Annet, Recreation area in Seine-et-Marne, France

The Île de loisirs de Jablines-Annet is a recreation area built within a natural curve of the Marne river, combining water zones with green spaces and recreational facilities. The site stretches across two municipalities and is organized into distinct zones for different types of outdoor pursuits.

The site was developed during the 1970s from former gravel extraction pits left along the river. This transformation into a leisure facility was part of a broader plan to create recreational spaces for the expanding population around Paris.

The site takes its name from the two communes it straddles, Jablines and Annet-sur-Marne, and is one of twelve regional leisure islands in Île-de-France. Its 400-metre supervised beach and nautical centre make swimming and sailing the main summer pastimes, while the Maison du Grand Lac offers 60 beds and a 300-pitch campsite, 150 pitches of which are reserved for groups.

There are two entrances: a car entrance on the Jablines side and a pedestrian entrance on the Annet side. The site has 2,100 parking spaces, plus 2,000 overflow spaces when it is busy. In high season it is open to the public from 10:00 to 18:30, and entry is charged. Some activities are accessible to people with disabilities.

The site features a cable wakeboard system that allows athletes to practice on water without relying on boats, offering a different approach to water sports. This facility draws regular visitors who seek alternative ways to enjoy water-based activities.
