Information, Permits Issued, Wheelchair Accessible
Knowledgeable rangers and volunteers are ready to answer your questions, provide directions, issue wilderness permits, and hand out maps and brochures at the Wilderness Center at Big Oak Flat Information Station.
Wilderness permits are required year-round for any overnight stay in the Yosemite Wilderness. Permits are not required for day hikes (except if hiking to Half Dome). Wilderness permits are only issued to a limited number of people for each trailhead in order to provide outstanding opportunities for solitude, as required by the Wilderness Act. Learn more about obtaining a wilderness permit.
Most of Yosemite is covered in snow during winter. Before planning a wilderness trip during this time, please ensure you're prepared for winter conditions.
