The Appalachian Trail Conservancy Welcomes You to ATCamp!

ATCamp is the Appalachian Trail Conservancy's (ATC) voluntary hiker registration platform. We encourage all overnight hikers to register their itinerary, including thru-hikers, section hikers, and groups. Registering helps reduce overcrowding on the Appalachian Trail (A.T.) and at overnight sites, in turn reducing the subsequent impacts. Registering also gives ATC and Trail managers valuable insight into Trail use trends. 

Permits: Please note that ATCamp is not a reservation system.

• All campsites and shelters on the A.T., except those in Great Smoky Mountains National Park, are first come, first serve.
• ATCamp does not reserve shelter space in the Smokies or hut space in the White Mountains of NH.
• ATCamp does not replace permits that are required in Great Smoky Mountains National Park, Shenandoah National Park, or Baxter State Park.
• Visit our permits page for more information. 

Safety: Conditions change constantly on the A.T. due to planned work, weather, etc. Check our Trail Updates page before you head out for the latest conditions, alerts, and closures, and read through our Hiker Resource Library to help prepare for your trip. Safety is your responsibility on the A.T.

2026 Trip Planning info: Check out our 2026 Hiker Prep Series for the latest information about how to plan a safe, fun, low-impact visit to the Trail. The series includes important information about what to expect in sections damaged by Hurricane Helene, and is updated each year.

Thank you for helping us protect the A.T. by registering your hike! Contact us anytime with questions.
