Permits & fees

Times have changed. Not that long ago thru-hikers only needed two permits during the entire 2,200-mile trek. Both were free and obtained at self-serve trailside kiosks. The purpose of the permits was to collect statistical data about how many people were using the trail so that the National Park Service could report this information to lawmakers and secure funding necessary to maintain the trail.


Today, the growing trend of user fees that is creeping through all of our public lands has made it onto the AT. 

Obtain Before Your Hike

Great Smoky Mountains National Park  (Tennessee/North Carolina)

The Park Service defines a thru-hiker as someone who begins and ends their hike at least 50 miles outside the park and only travels on the AT while in the park. Thru-hikers are required to have an AT thru-hiker's permit.

  • it costs $20
  • for couples and groups, each thru-hiker must obtain a separate permit
  • you are require to carry a physical copy/ printout of the permit
  • it's valid for 38 days from the date of issue (30 days before arrive at park + 8 days of hiking in the park)
  • permits are not rationed by date or date range
  • permits can be obtained online here


For northbound thru-hikers this means going online the day before you leave for the trail, paying the fee, and printing out the permit. The average hiker (who does not get injured early on and is forced to stay at Neel's Gap to recover) will reach Fontana Dam (the northbound entrance to the park) before 30 days. It is best to wait to get the permit until the last minute before you leave, that way you have wiggle room in case you are injured or some other unforeseen event slows you down.  

Obtain During the Hike

Shenandoah National Park

Hikers pick up permits at trail-side, self-serve kiosks at entrances to the park. They are free, do not need to be requested in advance, and do not require approval from a park official. There is no charge for hikers entering the park via the Appalachian Trail.

  • Northbound thru-hikers obtain their permit at a self-registration kiosk near the park entrance on Skyline Drive, 0.8 mile north of Rockfish Gap.
  • Southbound thru-hikers obtain their permit at a self-registration station 0.1 mile south of the sign marking the park’s northern boundary.
