    After Hours Access

    Bald Mountain & Dollar Mountain After Hours Uphill/Downhill Policy

    Starting Monday April 17th, Bald Mountain will be closed to all public traffic.  Traffic on Baldy will be restricted to construction and mountain operations personnel only.  Due to on-going mountain maintenance, big machine movement, and construction work for Trail Maintenance, Forest Health, and Warm Springs lift deconstruction and removal there is no route on Bald Mountain to allow for safe passage and usage of the terrain for uphill traffic or other forms of recreation.  We look forward to normal post-closure recreation on Baldy winter 23-24. 


    Dollar Mountain will continue to welcome all uphill recreation for as long as conditions remain safe.  The Dollar team will be mindful of trail conditions and surface when operating machinery on frequently used trails. Bitterroot access is forbidden due to avalanche concerns. Please remember to clean up after your furry friends, and avoid on-mountain machinery and terrain parks!

    Dollar Mountain After Hours Uphill/Downhill Policy

    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.

    Additional Details

    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.

    Equipment Policy

    Ski Equipment Use Policy

    When operated in accordance with the rules and regulations of the Sun Valley Ski Area, ski equipment is allowed, with the exception of ski bikes, snow trikes, snow bikes, plastic snowboards, sleds, discs, snow scooters, toboggans, and/or tubes, which are prohibited at the Sun Valley Ski Area.

    Adaptive Device Use Policy

    Sun Valley Company allows the use of adaptive devices or other “manually-powered mobility aids” designed for use on the slopes, including mono skis, bi skis, skibikes, and outriggers. Reasonable accommodation for users of on slope “manually-powered mobility aids” will be made so long as such use does not create an undue burden on the safety and efficiency of normal operations. Users may be required to load and unload safely with minimal assistance or participate in an approved adaptive program. Additionally, the Sun Valley Ski Area offers or will arrange for adaptive equipment when requested in advance by individuals wanting to enjoy sports at the Sun Valley Ski Area.

    Other Power-Driven Mobility Device Policy

    Sun Valley Company in conjunction with the USDA Forest Service established a public access policy precluding motorized equipment on slopes and trails within the established boundaries of the Special Use Permit granted for public skiing access. That policy remains in effect.
    The public access policy for Sun Valley Company was established to prevent serious harm to the environment and the natural resources. Due to the need to address soil integrity, erosion and vegetative concerns, the Ski Area has adopted a “no motorized” policy for the public during the summer season.
    Due to concerns with actual safety practices in the winter season, Sun Valley Company has determined that the use of any power-driven devices or vehicles by the public would conflict with our safety requirements necessary for the reasonably safe operation of our on-slope activities.

    Ski Patrol

    In 1936 the Union Pacific Railroad company opened the doors of Sun Valley, America’s first four season mountain resort. Billed as North America’s premier mountain recreation destination, Sun Valley became the standard for all mountain towns to follow. Concurrently, the Sun Valley Ski Patrol (SVSP), America’s first and longest-tenured ski patrol, began skiing the slopes of central Idaho’s Pioneer and Smoky mountain ranges.

    More than three quarters of a century later, the SVSP continues its tradition of world class service to our guests. Trained in skier safety techniques, advanced first aid, snow science, lift evacuation, avalanche mitigation and rescue, toboggan handling and mountaineering skills, members of the ski patrol are highly certified and skilled individuals.



    Originally the ski patrol was led by members of the U.S. Army’s famed 10th Mountain Division. In fact, Nelson Bennett, one of the SVSP’s original Directors, actually cut many of Sun Valley’s most famous runs by hand. Over the past eight decades, the patrol has continued to be an industry leader in the development of best practices within the ski resort profession. These advances range from the invention of the ski patrol toboggan in the 1940s to technological advances in computerized dispatch systems today.


    Ski Patrollers and Avalanche Dogs


    Ski Patroller


    The ski patrol staff encompasses 67 highly trained professional men and women who average approximately 17 years of service with many exceeding 40 years on the job. This unequalled level of service is one of the many shining lights of the Sun Valley Company brand. The team consists of world-class skiers who are dedicated to enhancing our guests’ experience on the slopes of world-famous Sun Valley.

    Skier Safety


    Skiing can be enjoyed in many ways. At ski areas, you might see people using alpine, snowboard, telemark, cross country or other specialized equipment such as that used by the disabled. Regardless of how you decide to enjoy the slopes, always show courtesy to others and be aware that there are elements of risk in skiing that common sense and personal awareness can help reduce. Observe the code listed below and share with other skiers the responsibility for a great skiing experience.

    Sun Valley trails are rated according to their difficulty relative to other trails on their respective mountains. Users of all ability levels should begin with easier trails before advancing.

    Responsibility Code

    1. Always stay in control. You must be able to stop or avoid people or objects.

    2. People ahead or downhill of you have the right-of-way. You must avoid them.

    3. Stop only where you are visible from above and do not restrict traffic.

    4.  Look uphill and avoid others before starting downhill or entering a trail.

    5. You must prevent runaway equipment.

    6. Read and obey all signs, warnings, and hazard markings.

    7. Keep off closed trails and out of closed areas.

    8. You must know how and be able to load, ride and unload lifts safely. If you need assistance, ask the lift attendant.

    9. Do not use lifts or terrain when impaired by alcohol or drugs.

    10. If you are involved in a collision or incident, share your contact information with each other and a ski area employee.

    *Winter sports involve risk of serious injury or death. Your knowledge, decisions and actions contribute to your safety and that of others. If you need help understanding the Code, please ask any ski area employee.

    In addition to Easier, More Difficult, Advanced and Experts Only runs, Bald Mountain offers five Family Areas where we ask our guests to "Go with the Flow." These areas are shaded in yellow on the trail map and include: Lower Broadway, Seattle Ridge, Lower College, Olympic Ridge and Lower Olympic and Mid and Lower Warm Springs. These areas are clearly marked with yellow on-hill signage.

    There are also three Slow Zones in which guests are asked to go "Very Slow." These areas include: Upper College, the Meadow Hill at the base of Seattle ridge and 42nd Street to the bottom of Lower River Run. These areas are highlighted in red on the trail map and are clearly marked with red on-hill signage.

    Areas beyond the ski area boundary are not patrolled or maintained, and Sun Valley assumes no responsibility for the safety or welfare of skiers in these areas. Rescue in the backcountry, if available, is the responsibility of Blaine County Search and Rescue, a service often very costly to the skier.

    Avalanche Awareness

    Though Sun Valley makes efforts to minimize risk of in-bounds avalanches, these natural events cannot always be avoided. Stay out of closed areas, do not ski alone, and be aware of your surroundings. Call Ski Patrol immediately if you witness an avalanche. Avoid deep snow and tree wells, as these areas expose skiers to risk of snow immersion injuries and fatalities.

    There is a big difference between closed areas within the ski resort and Baldy’s area boundaries.

    Closed Area

    Closed means closed. Areas are closed for various reasons – lack of snow, poor snow conditions, maintenance, wildlife considerations, grooming and most importantly – avalanche hazard and mitigation. In the interest of public safety, skiing in closed areas is against the law in Blaine County.

    Snow and weather conditions can change quickly. Avalanche gates open and close accordingly for your safety. Never enter a closed area. You may lose your pass or receive a citation from Blaine County Sheriff (class B misdemeanor). If you are unsure about terrain access, please contact the Ski Patrol. In case of emergency call 911.

    Ski Area Boundary

    Public lands extend beyond Baldy’s boundary ropes. You are on your own when you go out-of-bounds. Rescue is not imminent when you leave the ski area and avalanche hazards are no different than touring in remote areas.

    Avalanche Rescue Equipment

    Skiers need to use good decision making when leaving the ski area and…

    • Have at least a basic understanding of Avalanche Awareness
    • Know the avalanche hazard for Baldy’s Side Country
    • Ski with a partner
    • Carry a cell phone
    • Carry an avalanche transceiver, probe and shovel
    • Practice with your equipment!

    Skiers can practice their avalanche skills in Baldy’s automated Beacon Park. If you need assistance honing your skills or have questions about the avalanche hazard, stop by the ski patrol headquarters on top of Baldy or call the ski patrol at (208) 622-6262.

    Lids on Kids

    Kids' helmet and goggles

    NSAA promotes the use of helmets on the slopes. We urge skiers and riders to wear a helmet – but to ski or ride as if they are not wearing a helmet. NSAA views skiing and snowboarding in a controlled and responsible manner – not helmets only – as the primary safety consideration for all skiers and boarders. A skier’s behavior has as much or more to do with the safety of the sport as does any piece of equipment.

    In 2002, Lids on Kids debuted as a resource for consumers to learn about helmet use in skiing and snowboarding. This site contains FAQs about helmet use, fit and sizing information, general slope safety information, related articles and games, and testimonials about helmet use from well-known athletes, including US Ski Team members.


    Drone Policy

    Out of safety concerns for guests, employees, and resort property, as well as concerns for individual privacy, Sun Valley Company   prohibits the operation or use of unmanned aerial systems, or drones, by the general public – including recreational users and hobbyists – without the prior written authorization from the Company.  This prohibition includes drones used for filming or videotaping, as well as any drone use by media or journalists operating above or within Sun Valley Company boundaries. including property under the special use permit with the US Forest Service and Bureau of Land Management..       The general public are not allowed to transport drones on the ski lift or be carried uphill by any means without prior authorization.  This prohibition on drone operations or use extends to any drones launched or operated from Company property, as well as drones launched from private property outside of the Company boundaries.  Any authorized operation of aerial drones may be governed by Federal Aviation Administration (FAA) rules and regulations, local law enforcement, and/or U.S. Forest Service or BLM regulations, as well as those policies separately established by Sun Valley Company, which may include certification, training, insurance coverage, indemnification requirements, and waivers or releases of liability.  Any violation of this policy may involve suspension of skiing or snowboarding privileges, or the revocation of season pass, as well as confiscation of any drone equipment, and may subject violators to any damages, including, but not limited to, damages for violations of privacy and/or physical or personal injuries or property damage, as well as regulatory fines and legal fees.
