The Best Backpack for the Appalachian Trail Thru Hike

Every hiker needs a reliable, durable and comfortable backpack when experiencing the 2190 miles of the incredible Appalachian Trail, especially when they want to thru-hike it! You need to carry everything you need without struggling to take a step, falling over because of that huge pack or leaving stuff at home because you just can’t carry it.

You want a backpack that doesn’t dig into your back, shoulders, and chest after an hour or two on the trail. And most of all, you want to be organized, comfortable and just forget about your gear so you can soak up the amazing experience of being out there on the trail.

Yep, your backpack is pretty darn important!

That’s why we’ve put together this detailed buying guide. We’ll explain exactly what you need to look for when buying your backpack for the Appalachian Trail and then share our six favorite hiking backpacks that will be perfect for the job.

How to choose the best backpack for thru-hiking the Appalachian Trail?

There are several factors you need to take into consideration before you part with your hard-earned money and invest in a hiking backpack.

How heavy is the backpack?

You’re going to be spending hours on your feet every day so every ounce that you’re carrying will make a massive difference to how you feel. Like most people hiking the Appalachian Trail, you’ll probably want to ditch much of what you’re carrying as you go through your trip anyway, so start smart.

One great way to reduce this is to opt for a lightweight backpack that doesn’t compromise on space so you can pack in the value instead of struggling to carry the bag itself. Bear in mind everything that you will need to carry including a tent, camping gear, a stove, waterproof clothing, cooking equipment, etc. and chose a lighter backpack.

How durable is the backpack?

Don’t be tempted to save money for your trip by buying the cheapest backpack available because you’ll likely end up causing yourself no end of stress (and potentially extra expense) along the way. Choose a backpack that is durable and easy to repair.

That doesn’t mean you need to break the bank with one of the high-end options out there, but instead, assess the specifications and make your choices accordingly. Don’t skip this – it will make a massive difference to your experience of the trail and will save no end of stress and hassle in the long term. There’s no way you want to find a gaping hole in your pack when you’re out there on the trail.

And remember, thru-hiking the Appalachian Trail takes time. You’re going to be out there in the great outdoors for months at a time and so your backpack is going to be pushed to its limits. Not only will you have the changing weather conditions and temperatures to contend with, but you’ll also find no end of branches for your pack to snag on, rocks to help wear away the fabric and other hazards.

Does it use an internal frame?

You don’t have to use a backpack with a frame, but it will certainly help stabilize your gear and make your hiking trip more comfortable. If you do choose to use one, we recommend you opt for an internal frame. These help you stay more balanced on your feet, which is especially handy when you’re hiking more difficult sections of the Appalachian Trail and they’re more compact than backpacks with external frames.  You’ll also avoid the chances of getting caught on branches and other hazards too.

Is it easily adjustable?

The secret to enjoying a comfortable hike depends on your ability to adjust your backpack to fit your unique body shape, so be sure that the backpack you choose offers you this option. Look for backpacks with a hip belt, shoulder straps, lift-loader straps and a sternum strap that you can adjust whenever needed.

Is it big enough for your needs?

Hiking backpacks come in a wide variety of sizes so it’s important to choose on that is big enough to carry everything you need without being too huge that it’s impossible to carry. Smaller is almost always better. A backpack capacity of around 50 liters is usually best for the Appalachian Trail.

Bear in mind everything you want to take with you on the trip, not forgetting to consider the approximate amount of food you want to carry. You should aim to stop off to resupply every 7-14 days on the trail so you can minimize the amount you need to carry. Learn how to hike the Appalachian Trail in Sections here.

  1. I have been following a family on YouTube and all of them hiked the trail – including a backpack with a baby in the back! They have 6 kids and all of them had to carry back packs. Truely amazing how they were able to hike it in just over 5 months. I wondered what types of backpacks they were using – It would make sense to have one that has a frame inside to help with making sure everything is packed well 🙂
