Uphill Policy

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.

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.

Bald Mountain Policy – During the Season & During Operating Hours

Uphill travel by the way of foot, snowshoes, trax, or skis is not allowed between the operating hours of 9:00 a.m. and 4:00 p.m. Users must be descending by 9:00 a.m.  Exclusions may apply for unusual circumstances. These exclusions may include but not limited to special events, maintenance, etc.

Bald Mountain Policy | Pre-Post Season

Safety considerations, maintenance or operational requirements, grooming operations, snowmaking operations, special events, avalanche hazard mitigation work, wildlife or resource considerations, or construction, may cause public risk management issues to exist.  To protect the public from potential hazards that may exist from time to time, prior to the opening of the ski season, the ski area is authorized, with USFS pre-approval, to close areas subject to those potential hazards and to post signs at uphill access points closing those areas.

Bald Mountain Policy – During the Season & Outside Operating Hours

Outside of operating hours, there may be circumstances in which the ski area may eliminate uphill traffic or limit or restrict uphill traffic by designating specific times or days or routes that will be available for such use.  These circumstances might include safety, maintenance or operational needs, grooming operations, snowmaking operations, special events, avalanche hazard mitigation work, wildlife or resource considerations, or others.  The ski area is authorized, with Forest Service pre-approval, to perform any or all of these actions as deemed reasonable and necessary by the ski area.

All participants within the permit boundary are considered skiers and are subject to Idaho Statute title 6 chapter 11, 6-1106 Duties of Skiers.

Uphill Route Map

Sun Valley Company Special Use Permit Uphill and Downhill Travel Guidelines:

  • Uphill and downhill traffic must follow the designated routes. These routes will be marked with yellow markers indicating the path of travel. Users not adhering to the specified way and in violation of this policy may be subject to removal and other penalties.
  • Users must yield the right of way, and stay clear of ski area machinery (groomers, snowmobiles, and snowmaking equipment). When encountering areas undergoing winch operations, users are required to re-route their path of travel to avoid potentially unsafe situations.
  • Users must wear reflective clothing, a headlamp, and blinking lights at all times. 
  • Users must adhere to the trail and run closures. Blaine County Ordinance 86-4 - No skier except a member of the ski patrol, an employee of the U.S. Forest Service, sheriff, or ski area operator in the course of their employment, shall enter any closed area within the Special Use Permit area on the mountain.
  • Dogs are prohibited on Bald Mountain until further notice. Any persons with dogs, except for Sun Valley professional avalanche and rescue dogs, in violation of this policy will be asked to remove the dog from the resort area immediately and may be subject to other penalties. 
  • Mountain bikes are not allowed on Bald Mountain from November 1 - April 30 every year.
  • If you pack it in, please pack it out. Help us keep Baldy clean for future users.

There may be other circumstances throughout the season requiring closure, such as special events, maintenance, or avalanche mitigation. Every effort is made to allow access to Bald Mountain when it is safe to do so. The River Run and Warm Springs base areas and uphill access points will have signage when closures are needed, reminding and notifying the public of any temporary uphill traffic restrictions. Users are allowed to hike up before 9:00 am and after 4:00 pm when uphill restrictions are not in effect. People hiking up early in the morning must be descending the mountain by 9:00 am



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, 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 minimum 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.

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

Mike Lloyd - Ski Patrol Director

“The safety of our skiing and riding guests is our first priority. We view every day as an opportunity to meet and greet our skiing and riding guests and talk about safety on the slopes,” said Mike Davis, Director of the Sun Valley Ski Patrol. “As members of the Mountain Community, it is incumbent on everyone to respect each others’ space and desire to have an enjoyable experience on the mountain.” Mike Davis - Ski Patrol Director


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 and be able to stop or avoid other people or objects.

2. People ahead of you have the right of way. It is your responsibility to avoid them.

3. You must not stop where you obstruct a trail or are not visible from above.

4. Whenever starting downhill or merging into a trail, look uphill and yield to others.

5. Always use devices that help prevent runaway equipment.

6. Observe posted signs and warnings. Keep off closed trails and out of closed areas.

7. Prior to using any lift, you must have the knowledge and ability to load, ride and unload safely.

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.

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.

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.

Mountain Community

The Mountain Community encompasses our entire recreational landscape and is inspired by the idea that we all enjoy and engage in sport without competing with or interference from other mountain enthusiasts.

The Mountain Community reaches far beyond our local mountain ranges and includes everyone who shares a passion for and appreciation of the mountain lifestyle. The Mountain Community can be expressed through the three C’s: Community, Consideration for others and Common sense. Combined with a desire to enjoy as safe an on-mountain environment as possible, this philosophy exists as a key component of the Sun Valley Company’s Safe Skiing Initiative.
