Four Mountains to Uphill

Uphilling is a key ingredient to the Roaring Fork Valley’s rich, athletic culture, and Aspen Snowmass has offered skiers and riders access to uphill travel across its four mountains longer than most ski resorts.

For winter enthusiasts who just can't seem to get enough time on the slopes and want a unique on-mountain experience, uphilling is a great workout with a sweet reward. Morning skins up Buttermilk, moonlit tours up Aspen Mountain or Highlands, afternoons spent steadily climbing Snowmass—the peaceful moments of sliding up the hillside, taking in the views, and earning your snowy turns back down to the base are hard to beat.

Wildlife update: We are fortunate to share our lands with some amazing wildlife. We live in bear and moose country and we will sometimes cross paths with these wild creatures. For the safety of all, people and animals, please do not approach these animals to get a picture or video or for any other reason. Give them space and enjoy viewing them from a distance.


What is Uphilling?

Uphilling, also referred to as alpine touring” or “skinning,” is the act of traversing up a mountain on skis or a split board with specialized equipment including skins (the sticky coverings on the bottom of touring skis that prevent them from slipping on the snow) and specialized alpine touring bindings and compatible boots.

Where is Uphilling Allowed?

All four mountains at Aspen Snowmass accommodate uphill travel, but an uphill pass is required and uphillers are asked to follow the designated routes to ensure safety as well as a scenic and enjoyable route to the top. Learn more on each mountain's uphill page and routes below.

Know before you go: We will occasionally call for temporary closures for safety reasons, crowd-control, and snow mitigation, so it’s important to stay up-to-date with this information.
