Meet the A.T. Thru-Hiking Class of 2026
Who hikes the entire Appalachian Trail, and what is it like? Hear from this year's thru-hikers on what defined their 2,000+ mile journey.
Read MoreThru-hiking the Appalachian Trail (A.T.) is the adventure of a lifetime. It’s a mammoth undertaking that tests both endurance and mindset, and an experience many hikers describe as one of the greatest accomplishments of their lives.
What Is Thru-Hiking?
A thru-hike is a continuous, end-to-end walk of a long-distance trail within a single hiking season.
A thru-hike is a hike of the entire Appalachian Trail completed within 12 months or less, covering more than 2,190 miles of trail. Thru-hikers may travel northbound, southbound, or use a flip-flop itinerary.
All hikers who complete the entire A.T. are eligible to be recognized as 2,000-milers, the official registry and recognition program for thru-hikers and section hikers, administered and managed by the Appalachian Trail Conservancy (ATC). The ATC recognizes thru-hikes regardless of sequence or whether hikers carry a pack the entire way.
What to Expect
One of the most common questions hikers ask is how long it takes and how to plan a successful thru-hike.
An Appalachian Trail thru-hike is a demanding physical and mental challenge. The Trail is mountainous for its entire length, with rocky terrain and frequent elevation changes. While physical fitness helps, especially early on, most hikers find that completing their thru-hike depends more on mental resilience than physical strength.
Many thru-hikers get their “trail legs” within a month or two and settle into a daily rhythm of living outdoors, connecting with other hikers, and becoming part of the Trail’s community.
Most thru-hikers complete the A.T. in five to seven months, with the average thru-hike taking just under six months. Individual timing depends on pace, weather, and route choice. Northbound hikers must reach Katahdin before mid-October when the Trail to the summit closes, while flip-flop hikes typically offer the widest weather window.
About one in three hikers who attempt a thru-hike of the A.T. complete the entire Trail. Since the Trail’s founding, more than 20,000 completed thru-hikes have been reported to the Appalachian Trail Conservancy.
Preparing for an A.T. thru-hike requires both logistical planning and personal readiness, including:
- Choosing an itinerary, start date, and location
- Registering a thru-hike
- Understanding camping regulations
- Planning resupply points
- Proper gear

How to Thru-Hike the Appalachian Trail
Northbound (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
Southbound (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
Flip-Flop
Flip-flop hikes begin somewhere in the middle of the Appalachian Trail and change direction partway through their journey. This approach offers more flexibility, fewer crowds, milder weather, and easier terrain early on, while also helping reduce overcrowding on the Trail.
Flip Flop
Section Hiking
Section hiking the Appalachian Trail means completing Trail over multiple trips, with many taking years to hike the entire Trail. This method allows greater flexibility and fewer sacrifices than 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!

Storm Damage Info for 2026 A.T. Hikers
Hurricane Helene hit the southern Appalachians in late September 2024 and caused widespread, catastrophic destruction. Closures and detours due to the storm are still in effect, and Appalachian Trail (A.T.) hikers must take special precautions to stay safe help the land heal.

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.
