Uphill Access at A-Basin

Sponsored by Dynafit


Always display your valid uphill pass on the provided armband and always check terrain status before coming; uphill can close at any time. A red light at the bottom of the uphill route will indicate if uphill is open/closed.

Scroll down for a list of our uphill events.

22-23 Uphill Access Pass Info

EVERYONE must have an uphill access pass + armband. Pass must be visible while you are on the mountain. 

Uphill season passes are $99, or a $20 add-on to a 22-23 A-Basin full-season pass. $10 from each pass will be donated to the National Forest Foundation.

  • Please purchase your uphill access pass online. No on-site pass sales.
  • Collect your pass in person at one of our ticket windows 7 days a week between 8:00 a.m. and 4:30 p.m. 
  • You MUST wear the provided armband while skinning or hiking AND carry your uphill access pass with you.
  • The uphill access pass does NOT provide lift access. 
  • You cannot reuse a previous season's uphill pass. Please collect a new one. 


What if I can't get my pass before I go uphill for the first time?

Print your pass purchase receipt / confirmation email, or have it accessible on your phone. If ski patrol stops you for not wearing an armband with the proper pass, you can show them. 

Hours and Routes


BEFORE / AFTER winter operational hours, i.e. mornings and evenings 

Use any of the open frontside green or blue routes below mid-mountain / Black Mountain Lodge.  Travel to the summit is up Dercum's Gulch or Grizzly Road. Uphill access may be restricted for mountain operations or safety reasons.

Note on-mountain signage and DO NOT TRAVEL INTO CLOSED TERRAIN for your safety and the safety of our mountain operations team.

DURING winter operational hours - Restricted 

Do not travel above Black Mountain Lodge / mid-mountain after 8:30 AM.

When the lifts are turning, uphill access is restricted to the eastern / far left edge of High Noon between the Base Area and Black Mountain Lodge. When it opens, you may also use the longer uphill route through the trees (see map) during operational hours. 

Details on the uphill route through the trees

Our uphill skin track in the trees is a little over 1 mile in length. It starts on the left side of the forested area between High Noon and Sundance. Head up Sundance a bit to see the open gate on your right. Orange markers on the trees will guide you. Watch for downhill traffic when crossing the open runs. This meandering route is peaceful, beautiful, and unique. 



The East Wall, Beavers and Steep Gullies, and all terrain parks, are always closed outside operational hours. 

Entering closed terrain is prohibited. It is the user's responsibility to know what is open or closed. Please plan your route before beginning your skin. Sometimes ropes are moved temporarily to accommodate grooming operations. You still need to know what is open/closed and stay out of closed terrain. 

Closure notifications

If the mountain is closed to uphill access, a closed sign will be posted at the bottom of High Noon trail in the base area. Look for the flashing red light. If you are unsure, please ask. Uphill may close at any time.

2022-23 Uphill Events

Thanks to our friends at Dynafit, most of our 2022-23 uphill events will feature race and/or touring equipment demos! Our spring uphill events will be added, soon.

Spring casual "Uphill and Chill" events return in March! Check them out:




  • Please use a headlamp so our mountain operations team can see you while they work and so you can avoid hitting their equipment or other obstacles. 
  • You are considered a skier under the Colorado Skier Safety Act and should know "Your Responsibility Code".
  • The mountain may be closed to uphill access when avalanche control, snowmaking, race training, or other special activities are taking place.
  • Uphill users are warned that snowmobiles, snowmaking equipment, snow grooming, winch cat cables and other equipment may be encountered at any time on the mountain and you are responsible to stay clear of such equipment.
  • Dogs are allowed after hours but must be under control at all times. No dogs are allowed on the mountain during operating hours. Please clean up after your dog.
  • Users accessing the mountain outside of normal operating hours do so at their own risk. Operational conditions may be variable including, but not limited to; closures removed for grooming operations, unfinished grooming activities, unmitigated avalanche hazards and limited visibility. Use extra caution!


  • Uphill users who use the mountain during non-operational hours are asked to park in the Admin Lot (the small lot at the north end of the A-Frame) or in the parking area above the Admin Lot adjacent to Highway 6. See highlighted area above on the map.
  • The Early Riser, High Noon and Last Chance lots are locked at 6:00 p.m. Please plan accordingly.   

Picking up Your Pass 

  • You may pick up your pass and the required armband at one of our ticket windows between 8:00 a.m. and 4:30 p.m. seven days a week. 
  • If you would like to skin up before collecting your pass and armband, please print your email confirmation or have it accessible on your phone, and keep it with you on your first outing. 
  • Collect your pass and armband as soon as you are able to. Without an armband, ski patrol will be stopping you to check on your uphill pass status.​
