  • All uphill users are required to adhere to and obey all posted information and to be aware of trail closures and other operational considerations. Be especially aware of other skiers and riders approaching from above or below when on-mountain. Snowmobiles, snow cats, winch cat cable, snowmaking hoses and other equipment may be encountered at any time; the uphill user assumes all risks.
  • Use of all Terrain Parks is prohibited outside of normal operating hours.
  • Before and after daylight hours, reflective clothing is recommended.
  • Headlamps are required to be turned on while on the mountain after 4:30 p.m. and before 8:45 a.m. During these times, stay in the center of the trail for best visibility.
  • Climbing during operating hours with snowshoes, skis, snowboards, fat bikes  is prohibited.
  • Uphill access will only be permitted during winter 2022-2023 operating dates.

Permitted Hours

  • All Uphill travel may begin at 4:30 p.m. and must cease by 8:45 a.m. during the entire operating season
  • Pre-season access is not allowed due to snowmaking and grooming operations.
  • Post-season access is not allowed due to mountain operations such as road plowing.


  • Pets are not allowed on mountain at any time.
  • This allows for increased safety, especially outside of normal resort operating hours when snowmobiles and snowcats are present to prepare and maintain the mountain.

Designated Routes (View Uphill Map)

Stay on designated uphill routes at all times.

Uphill Skinning Route

  • When the upper mountain is open, the uphill skinning route is Warming House Hill > Lower Keystone > Upper Park > Yellow Brick Road > Paradise Bowl.
  • During early season, until the upper mountain is open down to Upper Park, do not proceed uphill past the junction of Peanut and Lower Keystone. A sign will indicate this specific area.
  • NO UPHILL ACCESS IS PERMITTED BEYOND PARADISE BOWL, including Silver Queen Road and Windy Gap.
Winter Biking Route
  • Fat Biking is only allowed before and after lift operations; before 9 a.m. and after 4:30 p.m.
  • Warming House Hill > Lower Keystone > Houston. Once you come to Bubba’s Skiway, please return to base area via Houston > Lower Keystone > Warming House Hill.

Descending Route

  • After 4:30 p.m. and before 8:45 a.m., downhill travel is restricted to Paradise Bowl > Yellow Brick Road > Upper Park > Lower Keystone > Warming House Hill. This allows for increased safety when snowmobiles and snowcats are present outside of operation hours to prepare and maintain the mountain.

Avalanche Danger and Explosives

  • Avalanche danger may exist at any time along many of the uphill routes. Following ANY amount of new snow, or wind, the Ski Patrol may be conducting avalanche control work, including the use of explosives.
  • NO UPHILL ACCESS IS PERMITTED WHEN THE SKI PATROL IS CONDUCTING EARLY-MORNING AVALANCHE CONTROL WORK. A red light will be deployed on top of tower 3 of the Red Lady Lift and at the base area to alert uphill users of this closure.
  • Hint: When the red light is deployed, it can be seen on our Base Area webcam. Look for the "glowing orb" on top of Tower 3 of Red Lady Lift. (View Webcams)


Participants must also beware of and avoid mountain hazards. These include, but are not limited to:

  • Snowmaking hoses – Danger, high pressure! Do not ski over hoses!
  • Snowmaking hydrants – Do not fall in open sites!
  • Snowmobiles – Make yourself highly visible to avoid collisions!
  • Grooming Operations – Give groomers a wide berth and make yourself visible to operators, do not assume they see you!
  • Winch Cat grooming operations – Dangerous cable! Under no circumstances may anyone access any area within the Resort where winch cat operations are taking place. Such work will involve cables stretched tightly across the terrain and is very dangerous. Skiing into them could result in serious injury or death. Respect strobe lights and signage.
  • Other hazardous areas, operations or conditions may exist on-mountain.
