The adventure of a lifetime

Thru-Hiking

Thru-hiking the A.T. is the adventure of a lifetime. But trekking the 2,190+ miles of the A.T. is no easy feat — make sure you’re prepared!

What to Expect

Completing the entire 2,190+ miles of the Appalachian Trail (A.T.) in one trip is a mammoth undertaking. Each year, thousands of hikers attempt a thru-hike; only about one in four makes it all the way.

  • A typical thru-hiker takes 5 to 7 months to hike the entire A.T.
  • After deciding when and where to begin and then registering your thru-hike, you will need to plan your resupply points and know the camping regulations along the A.T.
  • Learn the camping regulations along the A.T. and the ATC’s expectations for hikers who want to be officially recognized as a 2,000-miler.
  • In addition to these logistics, physical and mental preparations become important factors in a successful thru-hike. Learn more about all these subjects below.

FAQs

Voluntary thru-hiker registration

The voluntary thru-hiker registration is a tool that helps prospective thru-hikers share their start dates with other thru-hikers and plan their itinerary in order to avoid the social and ecological impacts of overcrowding.

Where to Start

nb-hiketypeicons-2
Starting in Georgia

Northbound

Starting in Georgia has long been the most popular place to start a thru-hike. But "popular" has led to "crowded" between March 1 and April 15. During this time, the southern end of the A.T. becomes a continuous stream of hikers during the day, with dozens of hikers clustered around campsites at night. The "nobo" hiker typically encounters wintry conditions in March and parts of April and hot, humid conditions in summer. Katahdin provides a dramatic finale; hikers should plan to arrive before October 15.

Flip Flop

Increasingly, hikers are choosing to start somewhere in the middle of the Trail. Generally, these itineraries offer a gradual progression from easier to more difficult terrain and more frequent resupplies. You can also avoid crowded conditions on the Trail and sold-out services in trailside villages. A mid-Trail start also enables you to follow more favorable weather conditions and at the same time help conserve the Trail.

Starting in Maine

Southbound

Starting a thru-hike in Maine is by far the most challenging way to tackle the Trail. Katahdin, the Trail's northern terminus, is regarded as the most difficult mountain on the entire A.T. The route through Maine involves extensive climbing and scrambling over steep, rocky, root-covered and muddy terrain. A heavy pack is required due to the distance between resupply points. It’s best undertaken only by experienced and fit hikers.

Bear Canister Lending Program

Bear canisters are the food storage method that provides the most flexibility and surety for camping anywhere along the A.T. – no trees required. To try a bear canister and stay safe during your backpacking trip, the Appalachian Trail Conservancy and BearVault have partnered with the Georgia Appalachian Trail Club, Chattahoochee-Oconee National Forest (C-ONF), Amicalola Falls State Park and four North Georgia outfitters to create a free program that makes borrowing a bear canister simple.

Equipment

The most predictable mistake thru-hikers make when they start is carrying too much stuff. Put as much effort into determining what you don't need as what you do.
