Frequently asked questions


How long does it take to thru-hike?

Most thru-hikers take between five and seven months. The average is a week or two shy of six months. Weather conditions tend to limit the amount of time available. Flip flop thru-hikes generally offer the longest window of good weather, southbound thru-hikes, the shortest.

How can I avoid crowded conditions and still hike the entire Appalachian Trail (A.T.)?

Increasingly, hikers are choosing to start somewhere in the middle of the Trail, with Harpers Ferry, West Virginia and Shenandoah National Park in Virginia the most popular starting location. These hikers head north to Katahdin, then return to their starting point and hike south to finish their hike at Springer Mountain, Georgia. This approach allows you to avoid the crowded conditions at the southern end of the Trail, reduce exposure to extremes in temperature, and start the A.T. in its most beginner-friendly terrain. Choosing these itineraries also helps with conservation of the A.T. More information about various thru-hike itineraries and the benefits they offer can be found here.

Where do I register my thru-hike?

Thru-hikers can register at ATCamp, which enables to help hikers to select less-crowded dates, help alleviate crowding, plan and prepare, and receive vital updates.

Be sure to 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 must acquire a backcountry permit for the Great Smoky Mountains National Park prior to arriving; northbound thru-hikers are encouraged to purchase a Great Smoky Mountains National Park A.T. 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-venomous 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.

What navigation and communication devices do I need to carry?

The Trail is very well-marked in most places, but not all. In federally designated wilderness areas, signage and marking is significantly less prominent. After a storm or other situations, the Trail may be hard or impossible to find.

In an emergency, a map and compass may be your most reliable source of information on how to get off the Trail to find help, locate an alternate route, or describe your location and access points to potential rescuers. Cell phones and navigation apps can both can be extremely valuable but are dependent on battery life; cell service is not available in many locations on the A.T. Satellite messengers and personal locator beacons can fill the gap in emergencies when cell service is not available (those with two-way communication capability are most useful to rescuers).

How hard is hiking the Appalachian Trail?

Hiking the entire A.T. 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, requires fording of streams that can be hazardous after heavy rains. Sections that could be described as flat or smooth seldom last long.

Because the time frame 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 A.T. 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 A.T. 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 day-by-day itinerary is not necessary for a successful thru-hike. In fact, it can set you up for a lot of discouragement and frustration. There are many things out of your control that can alter your plans on a thru-hike, such as weather or injury. Sometimes you may find an opportunity for a once-in-a-lifetime experience that sets you back. It’s important to remain flexible.  An outline of when you expect to reach specific milestones will be helpful to friends and family back home. It can help keep you on track, too. 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 at least $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. A new set of backpacking 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 4,000-6,000 calories a day and may be eating two to three times what you ate before your hike (though it may take a few weeks for the “hiker hunger” 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 20,000 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 A.T. in 12 months or less. These 12 months are not restricted to a calendar year.

What is a 2,000-miler?

A “2,000-miler” is a hiker who has walked the entire length of the A.T. and reported his or her hike completion to the ATC. The ATC has been keeping records of thru-hike completions since the A.T. was first connected in 1937. The 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 pathway 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.

Are courses available to help me prepare for a thru-hike?
