Some require a fee, while others are free and appropriate for the whole family. Remember the winter options in Yosemite at Badger Pass. Cross-country and downhill skiing, ice skating, sleigh rides, snowshoeing and snowmobiling are all possibilities. Always keep abreast of road and weather conditions within the park. Roads can also be closed due to construction.
Weather can change unexpectedly any time, but especially in spring and fall.
Wilderness permits are required for overnight hiking or camping in the backcountry. They are free, and can be picked up at several permit stations within the park. If you plan to use the backcountry in high season, you are urged to make a permit reservation well in advance of your trip. See Related Sites for further information. Traffic congestion is a huge problem in Yosemite on weekends and holidays in the spring and summer.
