Skinning Summit County's Ski Resorts

Crisp air, fresh snow, and amazing sunrises are par for the course when skinning up the ski hill before the resort opens. "Randonee" skiing, also known as Alpine Trekking or AT (and more affectionately referred to as “skinning”) is the act of ascending a mountain using one’s own power and specialized ski bindings and “skins” that attach to the bottom of skis. Skins are held to the bottom of the ski with a sticky substance and allow the ski to glide one way while gripping the other. Skins were originally made with animal skin, such as seal skin, which is where their name originated. Modern skins are made with artificial material with fibers that hold the skis from sliding back down as the skier glides forward up the hill.

Skinning has been growing in popularity as more and more people opt to skip the lift lines and ski using their own power. Arapahoe Basin is by far the most popular Summit County ski area for locals to skin in the early morning. Every morning as first light hits the peaks before the lifts start turning, a large group of dedicated locals take to the slopes to get some early morning exercise and get the first turns of the day. Breckenridge and Keystone are close second in popularity and each resort hosts randonee races every year.

Arapahoe Basin

Skinning at Arapahoe Basin is a treat that more and more people are starting to take advantage of. In order to facilitate some guidelines for the large crowds that descend on the resort every morning, A-basin requires uphill users to get a free Uphill Access Pass from the season pass office during operating hours. The uphill pass is designed to give the resort an opportunity to go over the rules for uphill access with individuals who are interested in participating. You can even bring your dog skinning at Abasin, as long as you are off the mountain by the time they open.

For a full list of rules for skinning at Abasin, follow this link. For a list of upcoming events at Abasin including upcoming Randonee races, follow this link.


Breckenridge Ski Resort does not require uphill users to get a pass prior to partaking in skinning up the resort, but they do require all uphill users to stay on designated uphill routes. The also ask that uphill users call the cat hotline at 970-547-5627 every morning before starting uphill. The hotline will allow the resort to control which routes uphill skiers take so they can avoid disrupting grooming operations. The list of approved uphill routes for Breckenridge can be found below.

Uphill users are however expected to be off the mountain by opening time and are expected to follow other rules that can be found at this link.

Copper Mountain

Uphill users are also required to turn around before the restrooms at the top of Collage before the resort opens. Uphill users at Copper Mountain are encouraged to contact ski patrol at 970.968.2318 ext. 66131 before venturing out to ensure they know where to avoid
