Cross-Country Skiing and Snowshoeing
Several marked winter trails are available, generally from mid December through March. Yosemite Valley usually doesn't have sufficient snow for skiing or snowshoeing.
Brochures (including maps) for each of the areas with winter trails are available as PDF files (200-500 kb in size).
In addition, the National Park Service offers ranger-led snowshoe walks from mid-December through March (conditions permitting). See Yosemite Guide for a schedule of current programs.
Downhill Skiing and Snowboarding
Badger Pass ski area is home to the oldest downhill skiing area in California and offers downhill skiing and snowboarding from mid-December through March.
