Les Thermes – Water Park in Strassen
Les Thermes is the large water park west of Luxembourg City, jointly operated by the municipalities of Strassen and Bertrange. The building already stands out from the outside, with its round aluminium-clad shape often compared to a spacecraft.

The swimming pool
Les Thermes has combined several water areas under one roof since opening in 2009. For swimming, there is a 25-metre pool with six lanes, plus a teaching pool, baby pool, wave pool, outdoor pool and whirlpool. For children and teens, the spray park and several slides add variety, including the 80-metre Giant Slide, the 30-metre Speed Slide and the Space Shuttle slide.
Beyond the pool area, Les Thermes includes a large sauna and wellness section. The complex is complemented by Vitaly-Fit, Escale Beauté and food options inside the building. In summer, outdoor areas such as the lawn and beach volleyball space add more room to stay after a swim. Les Thermes also offers aqua classes and birthday options for children. For visitors with reduced mobility, the site carries the EUREWELCOME label. Opening hours and tariffs may change with holidays, courses and individual areas, so it is worth checking the official website before visiting.
