Aspen Snowmass will be requiring an Uphill Pass for on-resort uphill access during the 2023-2024 season. For details and how to purchase learn more here.

Uphilling has become synonymous with Aspen Snowmass. We continue to honor this important part of our Valley’s athletic culture while maintaining safety and flexibility for all. Our rules are put in place to minimize conflicts between uphill and downhill traffic on the slopes and maximize everyone’s safety and enjoyment. Buttermilk, Snowmass, and Aspen Highlands will still provide uphilling access during operating hours. Aspen Mountain will continue with no uphill access allowed during operating hours.

Uphillers will need to remain on designated, signed routes during all operating hours. We will not be scheduling any blackout dates for the 2023-2024 season, however 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 public of the closure.

During operating hours, the designated uphilling routes will be treated much like a ski trail with an open or closed sign signaling if access is available at that time. We ask that all uphillers check the Aspen Snowmass App before heading out to see if their selected route is open.

Please be aware that no ski area services, including Ski Patrol, are available during hours that the ski areas are not open for business. Please call 911 in the event of an emergency during non-operational hours. You are responsible for your own safety at all times while on Aspen Skiing Company property.


Uphill Policies

  • Daily Resort Operations hours are from 8am-4:45pm. Uphilling is permitted from 5am until 10:30pm, except on Aspen Mountain where uphilling is not permitting during operation hours. There may be temporary closures due to safety, business levels or snow mitigation.

  • Uphillers must remain visible at all times. Uphillers must stay on the side of the trail and single file. We strongly suggest using lights and reflective clothing for nighttime ascents or early morning ascents.

  • Uphillers must have their strap with current year sticker and uphill pass visible at all times.

  • Uphillers must be aware that the slopes are being worked on by employees 24 hours a day, and to be on guard for snowmobiles, snow cats, and other vehicular traffic operated by Aspen Snowmass.

  • Uphillers must use designated uphill tracks stated on our four mountains. Designated trails are marked by orange signs, and in some cases, marked with rope to designate a lane.

  • Uphillers must be aware of downhill traffic and avoid blind spots.

  • Uphillers must stay away from all snowmaking equipment and may not cross snowmaking lines at any time.

  • All uphillers must have a valid lift ticket or pass to ride up any lifts. Audits may occur.

  • Uphill traffic may be restricted due to pre-season preparation, avalanche mitigation efforts, or ski area construction and maintenance activities.

  • Uphill traffic may be restricted or closed due to safety reasons, business levels, or snow mitigation.

  • As with downhill traffic, uphill traffic must obey all on-mountain signage, including closed runs and rope lines.

  • Carrying children or babies in backpacks or carriers is not permitted on any mountain at Aspen Snowmass.

  • Some trails may be closed to uphill traffic during pre/post season while snowmaking and grooming operations are in effect. Please respect these closures at all times.
