A wilderness permit is required year-round for backpacking or any other overnight stay in the Yosemite Wilderness. A wilderness permit is not required for day hikes (unless hiking to Half Dome) or for staying in lodging facilities and frontcountry campgrounds.
Wilderness permits are only issued to a limited number people for each trailhead in order to provide outstanding opportunities for solitude, as required by the Wilderness Act. Since many trails are very popular, reservations are recommended ($5 per confirmed reservation plus $5 per person). Of each daily quota for a trailhead, 60 percent can be reserved ahead of time. Normally, the remaining 40 percent are available on a first-come, first-served basis no earlier than 11 am the day before your hike begins as long as permits are available. However, in 2021, these permits are available online two weeks in advance and up to four days in advance. See below for more information.
Some especially popular areas have additional application procedures:
Follow these steps to get a wilderness permit:
1. Decide where you will begin your overnight hike.
Once you know where you want to begin your hike from, use the trailheads map [1.5 MB PDF] to determine the name of your trailhead. The trailhead information page has additional information, including quotas for each trailhead, parking information, and other details.
2. Check availability of reservations for the trailhead.
The trailheads report shows which trailheads are full for certain dates (as of the last-updated date shown at the top of the page). If the date or trailhead isn't listed, space is available for at least one person (but not necessarily for your entire group).
3. Apply for a wilderness permit reservation.
Wilderness permit reservations are processed by lottery 24 weeks (169 days) in advance of the hiking start date from mid-November through October. Submit your application as early as possible: popular trailheads fill up on the first day reservations are available and many other trailheads fill up almost as quickly.
Reservations are normally available up to two days in advance (in 2021, up to four days in advance), although popular trailheads fill up the first day reservations are available.
First-Come, First-Served Permits in 2021
Until April 30, wilderness permits are available on a first-come, first-served basis. Beginning April 30, wilderness permits will not be available in the park. Normally, 40% of wilderness permits are available on a first-come, first-served basis at park wilderness centers. Instead, this portion of wilderness permit reservations will be available online using a two-week lottery. Starting April 15, you can apply 15 days in advance of your desired start date, with the lottery running 14 days in advance. The last day to apply for a permit is four days before a trip.
A reservation is not a valid wilderness permit. If you have a wilderness permit reservation, you must go to any wilderness center during open hours one day in advance or the same day to pick up your wilderness permit.
The buildings are closed to the public and all education and interactions take place outside, with proper social distancing measures in place..
Frequently Asked Questions
1. Where can I camp?
The trailhead quota system limits use based on where you begin your hike, and in some cases, on where you camp the first night of your trip. After the first night, you may camp wherever you can hike to within the wilderness.
Since there are only a few designated campgrounds, you can camp anywhere you like, provided you follow all the regulations. The exceptions are near the five High Sierra Camps and in the Little Yosemite Valley area, where you must you camp at the designated campgrounds.
2. Can I camp in the frontcountry the night before or after my backpacking trip?
Wilderness permit holders may spend one night prior to, and one night after, a backpacking trip in a backpackers' campground (summer only; year-round at Hetch Hetchy).
3. Do I need a wilderness permit during winter?
Wilderness permits are required in winter—but reservations aren't needed from November through April. You must pick up a wilderness permit at the permit station closest to your starting point (when these permit stations are closed for the season, permits are available on a self-registration basis). Trailhead quotas are in effect during winter.
Additionally, due to increased popularity of the Snow Creek Cabin, a quota (six people per night) is 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 the Badger Pass Ski Area, 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.
4. I already have a reservation. Can I add another person?
You can add another person to your wilderness permit reservation for an additional fee as long as space is still available for that trailhead. If space is no longer available for that trailhead, you can try to change your reservation to another date or another trailhead (as long as space is available). Please contact the wilderness reservations office to request changes.
5. I'm beginning my hike outside Yosemite, but will end my hike in Yosemite. How do I get a wilderness permit?
If you are starting a hike from a trailhead located outside of Yosemite National Park, obtain your permit from the trailhead's managing agency, even if camping in Yosemite. Only one permit is required. Even if you plan to spend every night of a Wilderness trip inside Yosemite but your entry trailhead is outside Yosemite, you do not get the permit from Yosemite. If you are starting at a trailhead in Yosemite and wish to camp outside of Yosemite during your Wilderness trip, you will only need to get a single wilderness permit from Yosemite.
If your starting trailhead is outside Yosemite National Park, get your permit from the land agency that manages that trailhead. Common examples:
6. Is my permit valid if I leave the wilderness?
Continuous travel is a condition of a wilderness itinerary in which the user travels from a Yosemite National Park entry trailhead to the exit trailhead during the dates specified in the permit. Exiting the wilderness at any time during a wilderness itinerary invalidates the wilderness permit. In order to continue backpacking, you would need a new wilderness permit. There are two exceptions:
7. How can I talk to a wilderness ranger?
Can't find your question here? We have more answers to frequently asked questions. You can also speak to a wilderness ranger by calling 209/372-0826 (Monday through Friday, 9 am to noon and 1 to 4:30 pm, from March through early October).
8. Can a wilderness ranger plan this trip for me?
The Yosemite Wilderness has over 750 miles of trail to explore with a great range of elevation, ecological zones, and solitude. This backpacking trip, be it your first or fortieth, is a uniquely protected opportunity to provide maximum freedom to roam in Wilderness. So, in planning a trip, it is important to find the right experience for your interests, timeframe, and abilities. A good planning process will enhance your understanding of the park and your safety. Therefore, as part of the wilderness experience, park rangers can provide general guidance but will not plan a wilderness trip for you; you must plan your own trip. Use some of the resources you've found on this site, look at maps, and get planning!
