Uphill Policy at Buttermilk

Dates & Hours

Daily Resort Operations hours are from 8am–4:45pm. Uphilling is permitted from 5am until 10:30pm.

Buttermilk Policies

• Uphilling at Buttermilk will be allowed during operation hours of 8am–4:45pm on the designated routes marked on Main Buttermilk, Tiehack, and West.
• Dogs are prohibited between operational hours of 8am–4:45pm at Buttermilk during the ski season. Before and after operational hours, your dog will need to be under voice control or on a leash so as not to bother other guests or wildlife. Please pick up any pet waste and pack it out with you.
• 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. This is a new requirement and can be on your body or your pack.
• Uphillers must be aware that the slopes are in use 24 hours a day by employees, 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 4 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.
• 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 Skiing Company.
• 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.
  

• Main Buttermilk: follows the orange disks up Columbine from the base, snakes back in the woods and then crosses Midway Avenue to Ridge Trail to the top.
• Tiehack: Up Eagle Hill to Ptarmigan. Stay hikers right up Ptarmigan until you intersect with the top of Buckskin. Cross trail into the marked woods trail to Savio. Stay hikers left on Savio to the top.
• West: up Teaser to the Bridge, under the bridge and up to Ridge Trail to the top.

Please be aware that no ski area services, including Ski Patrol, are available during hours that the ski areas are not open for business.
