I spent a week at St Anton am Alberg this March 2018 with Ski World. The Apres ski is legendary.
Start at the Heustadl for retro style live music at 430pm at their terrace bar, located on the blue run home from the Galzigbahn.
Then at 6pm ski down to the Mooserwirt for some wild and wonderful oompah loompah, hoff on ice, eurovision experience. When the place shuts at 8pm you will see drunken skiing back to the base of Galzigbahn.
Head to Das Basecamp opposite Gampenbahn for some dance music and food.
We gave Taps and Krazy Kanguruh and miss because we heard it gets super wild with girls dancing in their bra tops. lol. We were too old for that ;p
There are many more nightclubs in the town but we had to call it a night as skiing was a priority.
