There are plenty of bars in Paso Tonale but the après ski scene is not particularly lively like in some other resorts in Europe. If you want a week of skiing and partying then Passo is probably not the place for you. However, if you want to Malle the most of the après ski that is on offer then the Paradiso Hotel has a nice bar which is often busy for après ski drinks, as is bar Heaven which often has decent happy hour drinks promotions.
Passo Tonale has a natural ice rink and Ponte di Legno has a public swimming pool with freer access if you have a lift pass. There is also plenty of winter walking to be found as well as skidoo excursions and tobogganing.
