Fees & Reservations

ENTRANCE FEE:
The Appalachian Trail is free for all to enjoy. No fees, memberships, or permits are required to walk on the Trail. However, the A.T. passes through numerous state and national parks, forests and public lands, a few of which charge fees or require permits or reservations to park or to stay overnight in shelters or campsites. Below is a list of where some permits and fees are charged.

OVERNIGHT PERMITS AND FEES:
Great Smoky Mountains National Park (Tennessee/North Carolina) - A permit must be obtained before entering the park. There is a self-registration facility at the Fontana Dam visitor center. Forms and a deposit box are also available at the "Fontana Hilton" for northbounders. Southbounders - you can get a permit at Bluff Mountain Outfitters in Hot Springs, or 1.3 miles east on Tenn. 32 from Davenport Gap at the Big Creek Ranger Station. Section-hikers (considered to be anyone not beginning and ending a hike at least 50 miles outside the park) can make reservations by calling GSMNP Reservations Office at (865) 436-1231. Anyone caught without a permit will be issued a $125 ticket!
Shelter Policy - Park regulations require that you stay in a shelter. While other backpackers must make reservations to use backcountry shelters, thru-hikers are exempt. From Mar. 15 to June 15, four spaces at each A.T. shelter are reserved for thru-hikers. If the shelter is full, thru-hikers can tent close by. Only thru-hikers are allowed to tent next to shelters, so they are responsible for making room for those who have reservations in the shelters.

There are overnight permits & Fees for Shenandoah National Park (Virginia), Green Mountain National Forest/Green Mountain Club (Vermont) , White Mountain National Forest/Appalachian Mountain Club (New Hampshire) and Baxter State Park (Maine)

So if 4 spaces are for thru hikers that don't need a reservation, and say 3--4 other spots are taken by additional thru hikers and then some weekend person shows up and says he/she made a reservation for a spot, would it be wrong to ask them to provide proof before you have to give up your spot as a thru hiker and sleep on the ground?
