Inyo National Forest:

Wilderness Backcountry

Activities like backpacking, hiking, skiing, mountaineering, and horse camping are allowed.Motorized or mechanical activities are not allowed in wilderness. Groups are limited to 15 people or less, in order to preserve the solitude and tranquility of the backcountry. There are maintained trails through the area to hike on, but no developed campground facilities.

Wilderness permits are required year-round for the following:

  • All overnight /multi-night trips in the Ansel Adams, John Muir, Hoover or Golden Trout wilderness.
  • All overnight /multi-night trips that start in Inyo National Forest and will be overnight in Yosemite, Sequoia or Kings Canyon Wilderness.
  • Day use into the Mt Whitney Zone.

Crossing Park Boundaries

The permit will be issued by Inyo National Forest if the trip starts from an Inyo National Forest trailhead, even if the first night of your trip will be spent in the adjacent national park. If your trip will start in Yosemite, Sequoia or Kings Canyon National Parks, contact the park to issue your permit.
  • If you will cross into an adjacent National Park boundary you must follow park rules while you are there. Please check with the parks for specific regulations.
  • For trips that will travel through multiple areas, check for regulations for each area you will visit.
  • One permit is valid for the duration of a trip, including traveling through adjacent parks and forests.
  • If you exit the wilderness for more than 24 hours or re-enter at a different location, a new permit is required.

Permit Types

    Overnight permit Trips lasting one or more nights require an Overnight permit. This includes trips that cross into national parks or elsewhere (i.e., Pacific Crest and John Muir trails).
    Visiting Mt Whitney or Exiting Mt Whitney
    The Visiting Mt. Whitney permit is for trips that approach the Mt. Whitney Zone from Crabtree Meadows or cross country routes. You can enter the Mt Whitney Zone and climb to the summit; however this permit type does NOT include exit down the Mt. Whitney trail to Whitney Portal. The Exit Mt Whitney permit is for trips that approach the Mt. Whitney Zone from Crabtree Meadows or cross country routes. This permit type allows you to climb to the summit and includes exit down the Mt Whitney trail to Whitney Portal. This includes the option to camp along the Mt Whitney trail. A quota limits the number of people allowed to exit each day. A Mt. Whitney Day Use permit cannot be used as part of an overnight trip to pass through the Mt Whitney area.
    Cross Country: The Cross Country permit is for trips that include off trail travel in areas of Yosemite, Sequoia and Kings Canyon National Parks where a smaller group size requirement applies. Check the website for the park you will visit to determine if you are entering an area where the group size is limited.
    • If your travel route is not limited use the regular overnight permit type.
    • If you are entering one of the limited areas, use the "cross country" permit type.

Group Size and Trail Quotas

  • Groups on separate permits cannot combine if they will exceed the group size limit.
  • Wilderness regulations limit the number of people in a group to fifteen (15) people.
  • Some areas of Yosemite, Sequoia and Kings Canyon National Parks limit the group size to eight (8) for off trail or cross country travel.
Trail quotas limit the total number of people that can start on a trail in the same day. The time of year that quotas are in effect can vary for different wilderness areas.
  • Trail quotas limit the total number of people that can start on a trail in the same day.
  • The combined number of people in all the groups cannot exceed the daily entry quota.
  • Non quota trails can have an unlimited number of groups; however each group cannot exceed the group size limit.
Entry Date and Exit Date
  • One permit is valid for the whole trip, be sure to indicate the full trip.
  • Trips cannot be longer than 14 days in one area.
  • Entry date is the day you will begin walking the trail. The Exit date is the day you will come off the trail.
  • All of your group must start on the entry date listed on your permit. Your permit will be invalid if you miss your entry date.
