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 . Operating Hours & Seasons 8 am to 5 pm daily. The Wawona Wilderness Center at Hill's Studio is closed seasonally from approximately mid October through late May. During this time, self-registration wilderness permits are available from outside the nearest permit station to each trailhead.
