What is Thru & Section Hiking?
Thru-hiking the Appalachian Trail
Thru-hikers complete the A.T. in 12 months or less, with most thru-hikes taking around 6 months. Thru-hiking is physically and mentally demanding, with only about 1 in every 3 thru-hikers completing the journey. However, many thru-hikers rank their hike as one of the greatest accomplishments of their life and carry their memories of the Trail with them forever. The ATC recognizes thru-hikes regardless of sequence or whether or not you carried a pack (and in fact, we recommend flip flop hikes as a way to reduce overcrowding on the Trail!). All successful thru-hikers are eligible for the ATC’s 2,000-miler program.
Section Hiking the Appalachian Trail
A section hiker completes the A.T. over a period of more than 12 months, with many taking years to complete the Trail. This method allows hikers to enjoy all the A.T. has to offer without making some of the sacrifices required for a thru-hike. All section hikers who complete the A.T. are eligible for ATC’s 2,000-miler program, no matter how long it takes!
Thru-Hiker FAQsWhere to Start
NOBO
The most popular way to hike the A.T., but also the most crowded from mid February to mid April. Expect cold early on and heat in the summer. Hikers should plan to arrive at Katahdin before October 15.
Northbound
Flip Flop
Flip-Flop hikes begin somewhere in the middle of the Trail for a flexible and less crowded itinerary. Enjoy milder weather, easier terrain early on, and more frequent resupplies while helping reduce overcrowding.
Flip Flop
SOBO
Starting at Katahdin means beginning with one of the toughest sections of the Trail. The remote, rugged terrain in Maine is challenging, with fewer resupply points early on, so this route is best for experienced and fit hikers.
Southbound
Quick Tip
Where Not to Start
Although you may tackle the A.T. in any order you wish, we advise that you don’t start with New Hampshire and Maine. These two northern states are much more rugged and challenging than other parts of the Trail with steep, rocky, root-covered, and muddy terrain that can be difficult for both beginners and veteran hikers planning their Appalachian Trail itinerary.

Report an Incident
While the Appalachian Trail is a relatively safe place to visit, that does not mean that there are not potential dangers while you are hiking or camping. If you see something, say something — this will help us keep the A.T. as safe as possible for our visitors.
Report an IncidentRegistering & Finishing Your Hike
ATCamp Registration
Thru-hikers can voluntarily register their hikes at ATCamp to connect with fellow hikers, share their planned start date, and help protect the Trail from overcrowding.
A.T. Hangtags
Hangtags distributed by the Appalachian Trail Conservancy are frequently seen dangling off an aspiring 2,000-miler’s pack, marking their intent to traverse the entire Appalachian Trail.

Finish Well at Baxter State Park
Celebrate the history and significance of Katahdin and your thru-hike by following these guidelines while hiking to the northern terminus of the Appalachian Trail. If you are supporting an A.T. hiker, learn how to do so before, during, and after their journey with tips on safety, communication, resupply logistics, and more.
Report a Successful Hike of the Entire Appalachian Trail
