How to Pack for an Appalachian Trail Thru-Hike

Rate this story:

Congratulations! You've done it! You've committed to the journey of a lifetime. After weeks, months or perhaps even years of toying with the idea, you've made a resolute decision to pursue your dream of thru-hiking the Appalachian Trail.

The initial flurry of emotional fireworks and confetti quickly gives way to a wave of anxiety. The reality of living out of a backpack for the better part of a half-year while traveling on foot between Georgia and Maine raises some unsettling questions. How do I eat? How do I poop? (Answer key: often and dig a hole.)

One question that is deserving of an aspiring thru-hiker's time and energy is "How in the world do I pack for this?"

Carry too much and you increase your risk of injury, unnecessarily reduce your pace, and above all, increase your likelihood of quitting due to constant physical discomfort.  All of your time, money and effort goes for naught.

Carry too little and you run the risk of death (in the form of hypothermia) or an increased likelihood of quitting due to psychological discomfort. Again, nothing to show for all your preparation efforts.

Needless to say, finding the packing sweet spot can make or break a hiker's experience.

Although the ideal pack will vary from one backpacker to the next, there's undoubtedly a bell curve when it comes to how much thru-hikers carry. Some will fall onto the extreme ends of this weight curve and happily march the AT's full 2,189 miles. Including a number of the Ten Essentials, let’s break down what one likely would (and would not) find inside the average thru-hiker’s pack.

Check out our AT Backpacking Gear List.

The Essentials

1. Shelter

Most AT thru-hikers carry a tent. A smaller although not insignificant minority carry a hammock. There is no one right answer; it's a matter of personal preference.

Because the AT offers more than 250 backcountry shelters, at an average of one shelter every eight miles, some will set out on the trail without a tent or hammock, relying solely on these three-walled structures. Don't do this. Shelters on the AT are first-come, first-served. If you arrive to a shelter already at capacity, you must either hike on to the next shelter, which could require several more trekking hours, or ask people to make room for you, which is poor etiquette and offers no guarantees.

What to look for: Regardless of whether you prefer a tent or hammock, weight and durability are two important criteria.

2. Pack

As the contents inside hikers' packs get lighter and more compact, so too does the pack itself. Nowadays the ideal pack capacity is going to fall somewhere in the 40L–65L range, depending upon how much gear a hiker is carrying, the gear’s compression, and how much food a hiker requires.

Simple, internal frame packs dominate the trail nowadays. More likely than not, added bells and whistles are unnecessary for the purposes of a long-distance trek.

What to look for: Again, durability and weight are important, but fit is the most important criteria for a pack. Different brands feature different fits, so it's advisable to head to your local REI to discover which pack is right for your torso and hips.

3. Sleeping Bag

The vast majority of thru-hikers are going to see sub-freezing temperatures. For this reason, it's advisable to look for a sleeping bag in the 15–20 degree range. Some will try to get by with a 30-degree bag, which is doable, although can present bone-chilling nights for anyone starting in Georgia prior to mid-April and anticipating finishing after late August.

The next biggest question is insulation material: down or synthetic? Each has its own advantages. Down is lighter and more compressible than synthetic materials at the same insulation value, but synthetic holds up better in damp environments and is cheaper. If pack weight is your primary concern, down is the best option.

What to look for: Again, pick a bag in the 15–20 degree range. If you’re sleeping in a quality, waterproof tent (i.e., you’re able to keep your bag completely dry), down is the preferred choice. Some bags contain water-repellent down, which offers some insulation even if it gets damp. If you’re sleeping in a tarp tent or a tent sans footprint or ground cloth, pick synthetic. A bag at three pounds or less is good, although most ultralight backpackers will aim for something closer to two pounds.

4. Sleeping Pad

A good night's sleep is absolutely essential to peak physical performance, and consequently, so is a sleeping pad. Whether you opt for a foam or inflatable pad, you'll want something to cushion yourself against the wood floor of a shelter or the rocks and roots under your tent.

What to look for: The ideal sleeping pad will be lightweight (around one pound or less for a regular-length pad), insulated and from a reputable brand.

5. Clothing

This is often the category where aspiring thru-hikers end up overdoing it. Hikers need clothing appropriate for the range of conditions they will encounter on the AT with minimal-to-no redundancies and nothing more. Anything beyond what's absolutely necessary is considered a luxury, and will often be shipped home within the first week or two. To put this in perspective, hikers need no more than two pairs of underwear (and some opt for zero), two pairs of socks, and for women hikers, one sports bra. This section could be a standalone article. You can get our full clothing recommendations here.

As for material, the important takeaway is this: never cotton! Cotton both absorbs moisture and fails to wick it away from your skin. It’s a poor insulator and retains odor more than its synthetic and wool counterparts. In other words, cotton garments put you at a higher risk of hypothermia and will have you smelling like a sewer faster than other fabrics (which won’t help your odds of catching a hitch into town).

For insulating layers, down offers the best insulation-to-weight ratio, but is also rather finicky. It's important to keep your down gear completely dry and may require a wash after any particular humid spells.

On a final note, hikers will want to designate a particular set of clothing exclusively for camp. Not only is reserving a dry set of clothes absolutely essential for protecting oneself against hypothermia, but having something clean(ish) to change into serves as a nice morale boost at the end of a grueling day. For many, this set includes a clean pair of leggings, underwear and socks, plus a down jacket.

What to look for: Synthetic and/or wool fabrics for hiking. Down, wool and/or synthetics for camp. Choose durable materials from reputable brands.

6. Footwear

Footwear is simultaneously the most important yet difficult item to prescribe to those looking to spend significant time on trail. This is a good reason to head to your local REI and have one of the green-vested gurus help you find an option with the appropriate fit for your foot.

There are a couple of points worth noting, however.

First, although the stereotype is for hikers to don a thick, heavy leather boot, in recent years more and more thru-hikers have been opting for trail runners. Some will do a combination of boots and trail runners depending on season and terrain. Others use trail runners exclusively regardless of circumstance. Trail runners dry out faster, typically cause fewer blisters (due to their less-rigid material), and are much lighter, allowing hikers to cover more ground, faster. Boots offer more ankle stability and protection against rocks, and are better suited for heavier pack weights.

Also, it's important to purchase something .5 to 1.5 sizes larger than your current fit. Hikers need enough space in the front of their shoe to prevent their toenail from bumping against the toe box while hiking downhill. The consequence for not adhering to this will be several lost toenails. Additionally, during the course of a thru-hike, feet will both lose their arch and swell. It's hard to predict how much a hiker's foot will grow, but one full size is usually a good starting point.

7. Water Purification

Some will claim that you do not need to treat water along the Appalachian Trail. As someone who has contracted giardia while backpacking, I am not in this camp. Treat your water.

8. Hydration Reservoir / Water Bottle

Water is important. Consider using a reusable water bottle or hydration reservoir to stay hydrated.

9. Stuff Sacks

Hikers will need a minimum of two waterproof stuff sacks: one for their sleeping bag and another for clothes. It is absolutely vital to keep both your sleeping bag and camp clothes dry at all times. Most thru-hikers will carry a third stuff sack for food.

10. Guidebook

AT guidebooks are essential for planning resupply options, shelter and campsite information, and learning about amenities offered at nearby towns. Maps offer the greatest detail for the surrounding terrain and provide the best insurance against getting lost. However, because the trail is well-marked with a white blaze about every 70 feet, the majority of thru-hikers choose not to carry maps, opting for a guidebook instead. The guidebook of choice for AT thru-hikers is AWOL's AT Guide.

11. First Aid / Hygiene

This is another area where a lot of hikers overpack. First-aid kits can be simple and hygiene products should include only the essentials.

What to include: Antiseptic wipes, gauze pads, antibiotic cream, duct tape, ibuprofen, sunscreen, hand sanitizer, a sewing needle, mini toothbrush, toothpaste, floss, toilet paper, fire starter and multipurpose soap.

The Almost-Essentials

1. Hiking Poles

Although technically not essential, I always recommend that hikers use trekking poles.  Not only do they absorb much of the impact on the downhills and consequently save your knees, poles can help to stave off the dreaded "T. rex effect"—large, muscular legs with disproportionately small, weak arms. And for those who use a tarp tent, hiking poles can also double as tent poles.

2. Knife / multi-tool

Although I went into my thru-hike thinking a knife would be as important to my getup as it is to Rambo's, it only ever got use cutting summer sausage. You really only need something sharp enough to cut through a dried cylinder of meat.

Popular options: A simple yet high quality pocket knife will do.

3. Stove / Cookwear

Believe it or not, not all thru-hikers use stoves. When battling excessively heavy pack weights, a warm meal at the end of the night can feel more like a luxury than a necessity. That said, most thru-hikers do carry stoves because a cold bowl of oatmeal or instant mashed potatoes tastes like punishment.

4. Headlamp

It gets dark in the woods. Look for something lightweight with at least 70 lumens; more if you plan on doing significant night hiking.

5. Electronics / Luxury Items

A smartphone is arguably one of the most versatile pieces of gear. It can double as a hiker's phone, computer, MP3 player, camera, notetaker and flashlight. Although many set out into the woods to disconnect, keeping in touch with the spouse or parent on a regular basis can prevent a lot of gray hairs back home. Other common luxury items include a mascot (action figurine or other memento), camp pillow, books or an ebook reader, among others.

And there you have it. A non-consensus, not-quite-exhaustive list of what you will and will not need to thru-hike the Appalachian Trail.

    Very good list. I hiked the trail in 2005 at 60 years old. I made my biggest mistake in carrying way too much food all the time. I was told that you should plan to arrive in town or a resupply point without any left over food. Should have followed that advice. I also would change my sleeping pad. I started with a 3/4 length thermarest. In Harpers ferry I changed to a full length and it was worth the change. Today I would take my BA Q-core-SL that is worth any extra weight. A comfortable nights sleep is so important as stated in the blog. Another change might be to take my BA tent instead of my Wunderlust that only used hiking poles to set up. Then the water filter. I used a Katadyne pump. Last fall I used the sawyer squeeze on the Long Trail but saw someone using the Platypus gravity works. Was so impressed with it that I went out and bought one. I think that some of these changes might be adding weight to my pack. I started out at 34 lbs. It got lighter in the mid Atlantics and heavier again in Hanover when I picked up warmer things again. I think overall, pack weight can be much lower than mine was. “Sleevless” 05

    • BA Q-Core SL is a great sleeping pad. A bit heavy for some of the ultralighters, but like you, I think a good night’s sleep is worth the few extra ounces. Congrats on your thru-hike, Sleevless. Hope to run into you at Trail Days this year. – Badger, 2011

  • Bob

    I was thinking – why the focus on carrying all of the supplies? Isn’t there a mechanism that would permit you to place extra supplies in it and roll it behind you tethered? Think about a sphere with rollers around it with a tether. You could hook the tether onto your waste or pack. Why lift something off the ground if it can roll behind you?

    • Rudy Breteler

      If the trail were all flat and smooth, that would be just fine. But it’s not.

    • Doug French

      I thought of that too while I was laboring with my pack the other day… Even a one wheeled cart behind you would be difficult to pull up steep embankments with large rocks. Not to mention the many steps one encounters.

      • Bob

        Thanks for the reply!

      • Bk Rammer

        …Plus you would have to change your trail name to, “One-Wheeled Trail Tool”….

    • Milo

      I just watched a video of an AT hike and they had to climb steep rock cliffs (with ladders in the cliff side) so your suggestion would be highly impractical in very short order. One other video poster weighed his pack in at 37 lbs.

  • Victoria

    Love this list for backpacking in general. However I feel one important item that was left out is…… a BEAR ROPE! (paracord with a carabiner) since it is important to be able to hang your food away from animals, so that you still have food in the AM. 🙂

    • Doug French

      Yes, very important… extra rope for a tarp too is a good idea… For those days you want to sit by a fire under the rain and dry out and be comfortable…

    • Glow Worm

      URSAC! after years of spending time hanging bear backs, there is nothing like rolling in camp and tying off the URSAC to a tree a hundred feet or so from my tent and spending zero time with ropes. Well worth the couple extra ounces that a proper bear rope weighs and no worry about not being able to get it back out of a tree.

      • David de Jonge

        newbie question but what is URSAC?

        • OpenThought

          I suspect twhat was meant was the Ursack {}, a lightweight food/bear bag made by Ursack from Spectra fiber. Some of their models have passed Interagency Grizzly Bear Committee (IGBC) testing. There is an effort to have their products accepted where a bear canister is required. Because it is resistant to grizzly attack, it can be tied to a tree or suitable object instead of the need to hang it. Most models are sold at REI.

          Ursack’s latest model [the Allmitey] adds the ability to withstand small critter attacks as well.

    I plan on hiking the trail, and I actually have another idea for food- A guide to edible plants along the trail. It would be a small, compact book that would allow for foraging a more healthy, diet filled with all the needed vitamins, save perhaps vitamin C and protein, which may be supplemented with protein bars and vitamin C tablets. For those looking to get away, and into nature, I think that would be optimal. In addition, it may help to cut back some alien weeds, such as pepper grass, that threaten the already present vegetation. And no doubt may save money if you use it often enough! Thoughts?

    • Cody

      I don’t want to completely put you off of a desire to forage while on the trail but, it’s just not practical to rely on. I just completed my Thru (summited Katahdin 9/29) and met a lot of people with books just like you described, however they were used as a supplement to existing food stores.

    • Rudy Breteler

      If you’re heading off for a bushwack or to a remote area, responsible foraging is a fine thing to do. But the AT is a very heavily traveled wilderness corridor. Thousands of people thru-hike the AT every year, and many times that head out for short trips. If everyone foraged, the vegetation along the trail would be quickly destroyed. Likewise, if everyone wandered off the trail for foraging trips, the woods around the trail would be quickly trampled and eroded. I believe that Leave No Trace principles allow for responsible foraging in some situations, but an AT thru-hike is absolutely not one of them.

      • Doug French

        Well said… you covered it all well

    • Austra Lopithecus

      People urinate and defecate all over the AT, and the untreated waste can transfer pathogens to the surrounding greenery. Don’t take a chance on eating that, and getting sick. This is one of the few situations where a Pop Tart is a better choice.

  • Wariteru Ooawageri

    But I loved the list!

  • Gary Whitman

    Hi iAm in the planning stages of doing the AT as a thru hike. My question is about my dog, other than the obvious what else will i need for him

    • Tiffany Dawn Kriston

      Many parts (maybe all) don’t allow domesticated animals (such as dogs) on the trails. I’d check before putting too much effort into packing needed items for you dog.

      • George Emmons

        There’s only 3 areas on the AT that don’t allow dogs..SMNF Baxter and can’t remember the other but another Nat Frst

  • Alan Robbins

    Very good list. I cannot emphasize enough the need for good fitting, comfortable footwear and reiterate your feet will increase in size as you progress along the AT. I strongly suggest – if you want to be successful and not fall out at the first hostel or road crossing – that you CONDITION YOUR BODY, break in your footwear and other gear WELL BEFORE hitting the trail. When you and your gear can hike 15 – 20 miles a day, several days in a row with no ill effects, you are near ready. Start small and build up to it so you can ENJOY the AT. It is magnificent. I have hiked the whole thing and loved it.

    • REI

      Thanks Alan for the great tips. We couldn’t agree more that happy feet = happy hiker.

  • Ruth Belmont

    Good list. You have almost completed all the things what to carry with us while hiking. But I would suggest that you must include trekking pole bag to carry the pole as it will make easy to carry the pole without any hazel. While searching online I found where you can buy trekking pole bag online. Thank You

  • Angelina Petrozza

    Do thru hikers pack their tent in a waterproof stuff sack so that the rest of their gear doesn’t get wet if the tent was out when it was raining?

  • Milo

    Never having hiked the trail, it would be reassuring to know distances between places where food supplies can be replenished. At about 15 miles a day (with one day a week off) it would take a little more than 5 months. I often time find the secret to doing something ambitious like this is to take an approach of least; in other words, better to do a few miles/day and maintain excitement/interest in continuing the next day rather than a lot of miles/day and be fatigued for days following. If shelters are placed about 8 miles distant, that could be good measure for travel a day. The list was helpful guide.

  • David deVaull

    what about adding a folding entrenching tool? one model folds to 18″, 24 oz., multiple uses to include hygiene issues, drainage around tent, defense, leveling tent area, breaking up firewood.

    • Forrest Ford

      Any extra weight you will want to get rid of after the first day. “why would i cary this 24oz shovel when I can dig a hole with a stick on the ground”. Drainage, sometimes you’ll get wet. Defense against what? I almost never make fires, too much work. Haha, every oz matters!
