We are continuing to offer the same after-hours uphill/downhill access on Dollar Mountain that has existed in years past. Uphill hiking is permitted outside of normal lift operating hours (typically from 4pm to 9am, weather and conditions permitting). There are no designated routes for after-hours access however the terrain must’ve been open the day prior (check the mountain report) and terrain parks are closed outside of operating hours. Access is permitted from Dollar Base and Elkhorn. Dogs are permitted on the mountain. We ask that guests please be considerate of others and clean up after their furry friends.
Sun Valley's uphill and downhill travel policy, approved by the U.S. Forest Service (USFS), allows access for uphill and downhill travelers outside of operational hours. Uphill travel within ski area boundaries poses significant safety concerns for uphill and downhill recreationists, ski area operators, and staff. Sun Valley's policy reflects our commitment to seek a balance between mitigating safety concerns of uphill travel as a recreational use within the downhill ski area/Special Use Permit area and the resort has been granted a Special Use Permit from the USFS.
To protect the public from potential hazards that may exist from time to time, prior to the opening of the ski season, during the ski season, and after the closing of the ski season, the ski area is authorized, with USFS pre-approval, to close areas subject to potential safety hazards and to post signs at uphill access points announcing the closure of those areas.
Sun Valley continues to work closely with the Ketchum Ranger District, Sawtooth National Forest, the Bureau of Land Management (BLM), and local organizations to build awareness and provide public education regarding uphill travel and recreational uses. Our goal is to find a reasonable balance between user groups who share a common interest in recreating within the Sun Valley Special Permit area in a safe, non-confrontational, and sustainable manner.
All participants within the permit boundary are considered skiers and are subject to Idaho Statute title 6 chapter 11, 6-1106 Duties of Skiers.
