Santa at A-Basin, New Year’s Eve Moonlight Dinner

High, steep and old-school on Loveland Pass.

A-Basin turns 80 this season and still feels like a skier’s hill: a small base, a summit at 13,050 ft and 73% advanced or expert terrain, including the East Wall and Pallavicini. It has the longest season in Colorado, often into late spring. Best for confident skiers; it’s now on Ikon, not Epic.
