Uphill Policy at Aspen Mountain

Aspen Snowmass will be requiring an Uphill Pass for on-resort uphill access during the 2025-2026 season. For details and how to purchase learn more here. Aspen Snowmass allows uphilling at its ski areas, this includes, skinning, hiking, and snowshoeing.

Uphillers will need to remain on designated routes at all times. We will occasionally call for temporary closures for safety reasons, business levels, and snow mitigation. This information will be posted on our website, our social media outlets, the Aspen Snowmass app, and we will have signage at the base of our areas notifying the public of the closure.

Access Hours

6am–9am & 5pm–10pm
NO uphilling permitted 9am–5pm or 10pm–6am

Aspen Mountain Designated Routes

2. Aspen Mountain Downhill: For safety, uphillers are required to use the designated downhill route: Copper, Copper Bowl, and Little Nell.

Aspen Mountain Policies

• Aspen Snowmass requires an Uphill Pass for all individuals traveling uphill on its four mountains. Uphill Passholders will be required to wear an Aspen Snowmass provided strap—on their body or pack—with a valid Uphill Pass visible within the sleeve while skinning or hiking. A valid lift ticket or pass is required to ride any lifts.
• Uphilling is permitted only on designated routes. Trails are marked by orange signs and, in some cases, roped lanes.
• Slope preparation, maintenance equipment, and snowmobiles will be in operation at any time day or night. Keep to the sides of trails; wear lights or reflective gear; avoid blind spots, snowmaking lines, machinery, and winch cat cables; and stay out of the way of snowcats and snowmobiles at all times.
• Uphill access may be limited or closed at any time for safety or operational needs, including avalanche control, snowmaking, events, or maintenance. Respect all posted closures.
• Dogs are prohibited on mountain at all times during the operating season.
