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 FAQs
Where 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.
