Frequently Asked Questions

How long does it take to thru-hike?

From five to seven months, depending on how fast you hike. The average is a week or two shy of six months.

How can I avoid the crowds and still hike the entire Trail?

Hike southbound, or “flip-flop.” Increasingly, hikers are choosing to start in Harpers Ferry, West Virginia, or somewhere else in the middle of the Trail; they hike to Katahdin, then return to their starting point and hike south to finish their hike at Springer. On flip-flops such as those you'll find some fellow hikers (without the crowds), better terrain to begin with, and better weather--but with some drawbacks. More information about traditional and alternative itineraries can be found here.

Do I have to register?

No. There's no formal thru-hiking registration system. But, let friends and family know where you are, what your itinerary is, and your “Trail name.” The A.T. passes through numerous state and national parks, forests and public lands, a few of which require permits, fees, or reservations to stay overnight in shelters or campsites. In some cases, the reservation system is different for long-distance hikers. You need to acquire a backcountry permit for the Great Smoky Mountains National Park in advance of arriving; northbound thru-hikers are encouraged to purchase a Great Smoky Mountains National Park AT backcountry permit just before leaving home.  

Do I have to worry about bears and snakes?

Most hikers see a few bears in the course of their hike of the entire A.T. Black bears, the only species native to the A.T., are generally shy creatures and avoid people, except in locations where people have been careless with their food and bears have become habituated. Hikers may see snakes occasionally, but most often the non-poisonous variety. More likely to be a threat to a hiker's well-being are ticks, which can transmit Lyme disease and other pathogens. In recent years, those in the midst of the increasingly large "bubble" of northbound thru-hikers may have found themselves exposed to norovirus, a short-lived but extremely unpleasant stomach bug. More information on these and other important topics can be found on our Health & Safety page.

Do I need to carry maps?

The Trail is well-marked, so many thru-hikers, who become skilled at following the blazes, try to get by without them. But, maps are quite useful for planning a thru-hike, and, in an emergency, are your best source of information on how to get off the Trail and find help or describe your location and access points to potential rescuers.

How hard is hiking the Appalachian Trail?

Hiking the entire Appalachian Trail is a grueling and demanding endeavor. It requires great physical and mental stamina and determination. The terrain is mountainous for its entire length, with an elevation gain and loss equivalent to hiking Mt. Everest from sea level and back 16 times. The treadway in many places is rocky or filled with roots or mud. Maine and sometimes other states require fording of streams that can be hazardous after heavy rains. Sections that could be described as flat or smooth seldom last long.

Because the window of time in which a northbound thru-hike can reasonably undertaken without specialized winter gear is limited to about seven months, the saying "No rain, no pain, no Maine" has become an apt mantra. Those who are physically fit may have an edge, especially in the beginning, but ultimately completing the A.T. is more of a mental challenge. The Appalachian Trail has been hiked by people ranging from age five to 86 and by hikers with a wide range of disabilities.

If Hiking the Appalachian Trail is So Hard, Why Would I Want to Do It?

Walking the entire Appalachian Trail in a continuous journey is one of the most rewarding, exhilarating, and memorable ways you can spend six months of your life. Thru-hiking enables you to immerse yourself deeply in the natural world and view some of the most beautiful, wild and pastoral landscapes in the United States. Thru-hiking will also give you the opportunity to form friendships with people of all ages, from all walks of life, and from around the world.

How detailed should my plan be?

A detailed itinerary is not necessary for a successful thru-hike, but an outline of when you expect to reach specific milestones will be helpful to friends and family back home and keep you on track. Be mindful that family members will worry if you do not check in on schedule; make sure they know you cannot entirely predict your schedule and that cell phone reception is spotty. Also inform them that you may keep your phone turned off much of the time to save your batteries and protect your phone from inclement weather.

Northbound thru-hikers are advised to start out hiking only eight miles a day the first week, and very gradually increase mileage over the next several weeks. By some point in Virginia, most hikers will have gained their "trail legs" and will do their biggest miles from there through Vermont, where terrain is overall less challenging than the southern states. In the extremely rugged terrain of New Hampshire and Maine, northbound hikers can expect their mileage to drop as much as 30 per cent, even though considerably more effort is required. 

What are my chances of finishing a thru-hike?

One in four thru-hikers report completions to ATC. The most common reasons for a hiker leaving the Trail sooner than planned is due to an injury, running out of money, family matters at home, or finding the experience was not what was anticipated.

How do I know if I’m ready?

The smartest thing you can do is to take a practice hike that includes at least two nights on terrain that approximates the part of the Trail you plan to start on. This will help you evaluate gear, physical conditioning, and mental readiness.

How much does it cost?

Most hikers spend an average of about $1,000 a month during the hike itself. Disciplined, frugal hikers willing to forego motels, restaurants, and other amenities can get away with less; those who like to stay in motels and eat at restaurants when they have the opportunity can easily spend much more. New gear runs $1,200 to $2,000 or more. Lightweight gear is usually more expensive, but many hikers ending up purchasing smaller packs and lighter gear along the Trail, replacing their initial purchases of heavier gear. Doing extensive research ahead of time can pay off.

What will I need money for?

Aside from trail food, most of your money will be spent in town. Few thru-hikers can resist the temptation of restaurant food, motel beds, and hot showers after days of deprivation. Keep in mind that you will be burning 4-6,000 calories a day, and may be eating two to three times what you ate before your hike (it may take a few weeks for a "hiker appetite" to kick in). You will also need money for supplies, laundry, postage, equipment repair, and equipment replacement. The more days you spend in town, the more money you will spend. Be sure you have money for a possible emergency trip back home.

There are also a few fees hikers will encounter along the Trail. An A.T. Thru-hiker permit in the Great Smoky Mountains National Park costs $20 and must be purchased in advance. Some overnight sites require fees, particularly in New England. These sites typically range from $5 to $10 a night, but there are usually alternate sites without fees available within a few miles. In the White Mountains of New Hampshire, the most attractive options for overnight stays are a system of full-service huts that run more than $100/night for meals and lodging. A limited number of thru-hikers can take advantage of the work-for-stay options; more about the alternative overnight sites in this area can be found here.   Hikers should be prepared to pay a campsite fee in Baxter State Park in Maine. 

How many hikers have completed the entire A.T.?

More than 14,000 hike completions have been reported to ATC. This includes hikers who have completed the Trail over many years as well as those finishing in one trip. More facts and statistics can be found here.

How does the ATC define thru-hiking?

We define a thru-hike as a hike of the entire Appalachian Trail in 12 months or less.

What is a 2,000-miler?

A "2,000-miler" is a hiker who has walked the entire length of the Appalachian Trail and reported his or her hike completion to the Appalachian Trail Conservancy. The ATC has been keeping records of trail completions since the A.T. was first completed in 1937. ATC uses the term "2,000-miler" as a matter of tradition and convenience. When the term was coined, the A.T. was only slightly more than 2,000 miles. Its length changes every year due to relocations. In recognizing 2,000-milers, we don't consider issues such as the sequence, direction, speed or whether one carries a pack. We do expect that persons applying for inclusion in our 2,000-miler records have made an honest effort to walk the entire Trail. A 2,000-miler application form can be found here.
