The operation of the St-Léonard underground lake will be suspended for several months.
During the winter of 2019-2020, the underground lake will undertake the complete renovation of all the outdoor spaces on the site. A new reception building with shop, refreshment bar and meeting rooms will be built to welcome visitors in optimal conditions. A brand new educational area will also be created, which will make the visit to the site even more attractive. As a result, the winter closure will exceptionally be extended from the evening of 22th September 2019 to 6th June 2020.
