About the Calypso 2000 swimming pool

The Calypso 2000 swimming pool (Watermael-Boitsfort pool) is located in the Trois Tilleuls Sports Park, just steps away from Place Keym. This pool offers a comprehensive setting for aquatic activities catering to a wide audience, including individuals, school groups, and sports clubs.

The Calypso 2000 swimming pool features a 33-meter main pool with 6 lanes, a paddling pool for children, and an outdoor solarium accessible during the summer. The pool also offers various classes such as swimming, aquagym, and aquabike.

Additionally, various resident clubs organize individual and team sports activities such as competitive swimming, diving, and water polo.
Built in 1970, the pool has undergone several phases of infrastructure modernization, incorporating a cogeneration system and eco-efficient equipment to reduce its environmental impact and enhance visitor comfort.

The Calypso 2000 swimming pool is managed by a municipal non-profit organisation (ASBL).
