Wilderness in Winter
Where can I go?
Most winter users enjoy the marked winter trails around Badger Pass (elevation 7,200 feet), Crane Flat (6,200 feet), or in the Mariposa Grove (5,600 to 6,600 feet). Roads are maintained in these areas, although chains are often required. Each area has beginner, intermediate, and advanced trails, which range in length from less than one mile to over 20 miles round-trip. These trails are marked with colored triangular or rectangular signs in trees. Most summer trails cannot be seen or easily followed in winter.
You can download winter trail brochures for these three areas.
Many good overnight or multi-day trips originate in the Badger Pass area. Overnight wilderness users must get a free wilderness permit at the Badger Pass Ranger Station and leave their vehicles in the area designated for overnight parking.
Another popular trip for more advanced skiers and snowshoers leaves from Yosemite Valley and heads toward Tuolumne Meadows via the Snow Creek Trail. There is a potential for avalanche hazard along this route and users should be competent in avalanche assessment, winter backcountry travel, route finding, and winter camping. This trip requires intermediate ski skills and winter survival competency at a minimum. Get your wilderness permit and more information at the Yosemite Valley Visitor Center.
Wilderness Permits, which are required for all overnight Wilderness trips in Yosemite, may be obtained at the Big Oak Flat Information Station, Yosemite Valley Visitor Center, Badger Pass Ranger Station, Wawona Visitor Center, or Hetch Hetchy Entrance Station. Please register at the station closest to your starting point. From November through April, wilderness permit reservations are not necessary or available.
In general, winter Wilderness users must camp at least one mile away from a plowed road. Camping is not allowed within 1½ miles of the Badger Pass ski area boundary. Camping is also not allowed at Summit Meadow, Dewey Point, or Glacier Point (camping is permitted near both points, but not at the points themselves).
Camping is not allowed in the Tuolumne Grove. Camping in the Mariposa Grove is permitted only above the Clothespin Tree in the upper grove from December 1 to April 15. At other times, camping in this area is prohibited.
Typically the Four Mail Trail, and sections of the John Muir and Mist Trails, are closed during the winter (portions of the John Muir and Mist Trails remain open, so it's still possible to hike to the tops of Vernal and Nevada Falls and to Little Yosemite Valley, though these trails are often snowy or icy). Check for winter trail closures before your trip.
Ostrander Ski Hut is a two-story stone structure beautifully crafted in 1941 by the Civilian Conservation Corps for cross-country skiers. The hut sits in a small glacial cirque at the edge of Ostrander Lake, elevation 8,500 feet--a 10-mile ski from Badger Pass. Very basic overnight accommodations and cooking facilities are available at the hut. It sleeps 25 people and has bunks, mattresses, a wood stove, a kitchen with a gas stove for cooking, and assorted pots & pans. Drinking and wash water is hauled from the lake in buckets; treatment is the individual visitor's responsibility. Solar powered lamps provide light.
Ostrander Hut is operated by the Yosemite Conservancy, a non-profit educational organization in Yosemite National Park. The hut is typically open from late December until early April. A hut keeper lives at Ostrander during the winter.Due to Ostrander’s popularity, early reservations are awarded by lottery. After the lottery, remaining reservations are available by phone. Yosemite Conservancy's website has details about Ostrander Ski Hut and the reservation process (including a calendar of available dates).
Rental skis, snowshoes, and cross-country ski lessons are available through the Yosemite Nordic Ski School at Badger Pass (209/372-8444).
In order to maintain the pristine quality of the Yosemite Wilderness, please follow these guidelines when camping during winter:
Dangers do exist in the Yosemite Wilderness and even small problems can become deadly if winter users are not prepared. Use common sense and caution when planning a trip, keeping the weakest member of your group in mind. Altitude and cold weather sap more energy.
Winter in Yosemite is typically a mixture of beautiful, sunny days interrupted by cold, snowy days. Conditions can change from one to the other in a matter of hours, so you should be prepared for both each time you go out. Winter conditions generally exist from November through April, although early and late storms may occur at any time. Temperatures at 4,000 feet in Yosemite Valley are usually in the 40s to 60s during the day and 20s at night, with temperatures in the high country from 10 to 25 degrees cooler. Storms vary in length but can last for days and can be followed by another. Up to 15 inches of snow may fall in a short time. The high country generally averages three to ten feet of snow on the ground through the winter. (Check current conditions.)
