Although it is recommended, but strictly speaking not necessary: You can enjoy St. Anton even without touching a skiing slope once. Here is a selection of some popular places:
Ski to door (but also easy to reach on foot), the Après Ski Party goes on in the Crazy Kangaroo. Since 1965.
Thus the nightlife in St. Anton has not yet been exhausted, TripAdvisor is coming up with many more.
Or, for pragmatists: drift easily through the pedestrian zone, anywhere you end up then - spontaneously is mostly funniest, too.
