Wilderness in Winter - Yosemite National Park (U.S. National Park Service) Another popular trip for more advanced skiers and snowshoers leaves from Yosemite Valley and heads toward Tuolumne Meadows via the Snow Creek Trail. Due to increased popularity, the Snow Creek Cabin now has a quota (six people per night) in effect. This limit on the number of people staying at the cabin provides for visitor safety and preserves natural, cultural, and wilderness values. You must go to the Valley Visitor Center to pick up a wilderness permit (if available) and current combination for the cabin's lock. Permits are available one day in advance of your trip. Reservations are not available. The cabin is generally open during the same time as Badger Pass, which is typically mid-December through March (as long as there is enough snow for skiing). The cabin is closed at other times of the year.
