Beyond the developed areas, Yellowstone offers a diverse, mountainous landscape that invites exploration by foot, pack stock, and boat. Hundreds of miles of trails and over 300 designated backcountry campsites facilitate travel throughout the park. Permits are required for all overnight stays.
When planning a backcountry trip, remember that many of Yellowstone’s trails are more than 7,000 feet above sea level. Most areas retain snow until late May or early June, and some (especially mountain passes) are snow-covered until late July. Also, many routes require fording rivers that can be 25 feet wide, 3 to 6 feet deep, extremely cold, and swiftly running during our late spring runoff. It’s hard to tell from a map whether a stream will be a raging torrent or merely a swollen creek.
NOTE: The process for obtaining a backcountry permit has been modified for the 2020 season.
Permits are required for all overnight stays and must be obtained by calling the Central Backcountry Office. Permits are available Monday through Friday from 8:00 am to 4:00 pm.
All backcountry permits are being issued via phone and e-mail only.
Permits are available no earlier than 2-days prior to the start of your trip*. To obtain a backcountry permit: Call the Central Backcountry Office at 307-344-2160. Before calling, you may email a copy of your completed Backcountry Permit Application to speed up the process. A copy of your permit will be emailed to you after we speak with you and obtain payment information.
* If you are looking to start a trip on Monday or Tuesday you can contact our office on Friday to obtain your permit.
Is your trip start date more than 2-days away? If yes, then consider making an Advanced Reservation for the backcountry permit. Advanced reservations do not take the place of obtaining the backcountry permit, but offer a way to guarantee specific campsites well in advance of your trip. Only a portion of the park's backcountry campsites may be reserved in advance. Reservation applications are accepted by mail or fax only. A flat, nonreundable fee of $25 is charged for each reservation. Complete the Backcountry Reservation Application and submit by fax or mail.

Annual Backcountry Pass
For individuals taking several or extended overnight trips in Yellowstone's backcountry, we offer an Annual Backcountry Pass for $25. Valid for one season (Memorial Day to September 10), the Annual Backcountry Pass exempts the pass holder from the per-person per-night fee. The pass does not cover the advanced reservation fee.
Each designated campsite has a maximum limit for the number of people and stock allowed per night. The maximum stay per campsite varies from 1 to 3 nights per trip. Group size limits range from 4 to 12 people. With the exception of four campsites, we allow only one group at each campsite. If your group size exceeds the campsite limit, you’ll need to obtain a second permit and cook and sleep as separate groups. A food storage pole is provided at every campsite so that food and attractants may be secured from bears. Some sites have fire pits. A list and map of campsites can be found in the Backcountry Trip Planner .
Several commercial businesses are permitted to offer guided overnight backpacking trips into Yellowstone's backcountry. These businesses obtain the necessary permits for trips they provide.
