Vallée de Joux holds a few sledge runs, that you have you climb yourself, which make every gliding enthusiast happy each winter. The longest run is one kilometre long and is situated on the top of Col du Marchairuz. Other easier runs are found in Le Brassus, Les Chabonnières and on the Col du Mollendruz.
 
When Lac de Joux freezes enough, you can go ice-skating or simply walk on it. This huge natural ice rink also allows parents to sledge their children across it and in a short time laughter and cheerful shouting fill the area. A wonderful playground for all ages!
