If you plan to use the park campgrounds, remember that the regular time limits and fees apply to researchers. In general, you may stay in Yellowstone campgrounds no more than a total of 14 days between July 1st and September 15th and for 30 days during the rest of the year. Most front-country campsites require advanced reservations.

You will need a backcountry permit for any overnight backcountry work. Backcountry permits are available at most Visitor Centers. Backcountry campsites can be reserved in advance for $20 or you can reserve a permit no more than 48 hours in advance for free. However, the actual permit needs to be picked up at a Backcountry Office before your hike. Backpacking regulations and advance reservation forms are available on request by downloading the online Backcountry Trip Planner, or by writing to:

Backcountry Office
P.O. Box 168
Yellowstone National Park , WY 82190

or call: 307-344-2160.

Camping is regulated in Yellowstone to protect the natural resources. If your study requires an overnight stay away from a designated campsite, you must obtain special authorization when you apply for your research permit or renewal. You must also obtain a backcountry permit for camping in an undesignated campsite. Apply for authorization prior to your fieldwork by contacting the Research Permit Office at (307) 344-2234.
