Lac de la Cavayère is a 18-hectare artificial reservoir created in 1988 to prevent flooding in the Aude river basin and provide a recreational site for the city of Carcassonne. The lake features three distinct sandy and pebbled beaches monitored by lifeguards during the peak summer months. It serves as a hub for the O2 Aventure park, which offers high-rope courses through the surrounding pine forests. Visitors can access a dedicated water-skiing lift and rent paddleboards or pedal boats on the lake surface. The perimeter path surrounding the lake spans approximately 5 kilometers, making it a popular route for joggers and walkers. The site includes designated picnic areas, barbecue zones, and snack kiosks throughout the grounds. Swimming is strictly regulated to designated areas and is prohibited outside of the monitored beach zones. The surrounding hillsides offer a Mediterranean landscape characterized by dry scrubland and forested patches.
