The 4 Major Differences Between the AT and the PCT

Check out our brand new resource for thru-hiking the PCT, Pacific Crest Trials.

As a 2013 AT thru hiker, just over a year has passed since my last day on trail and already I feel the pull. Many of us leave the AT with dreams of another trail but instead return to jobs, school and  normal life again. Still, the restlessness is always there and becomes stronger and stronger.. I feel it now and it has lead me to do some extensive researching for the Pacific Crest Trail, the west coast brother of the Appalachian Trail. The PCT, which was completed in 1993, runs from the Mexican border in California through Oregon and Washington, ending in Canada. It is an entirely different beast than the AT, with the most stark contrasts covered in this article. For those of you interested in another bout with trail life, read on!

The 4 Major Differences Between the AT and the PCT

1. Terrain Changes


The most obvious difference between the AT and the PCT is the terrain. The AT more or less travels through deciduous forests for the majority of the trail. At times you pass through cattle fields and cropland. The White Mountains introduce you to the coniferous forests of the alpine regions and Maine takes on its own special identity. Still, for the most part you do not see an extreme change in the terrain types. Trees, trees, and more green, luscious trees.

The PCT, however, begins in the Mojave desert; limited water, cacti, sage brush, the occasional sightings of Roadrunner and Wiley Coyote (Okay, that last part is not true). The desert then fades into the Sierra Mountain Range. The High Sierra, being an alpine region, nearly always means snow for hikers (aka, post-holing up a pass and glissading down); a vast change from the heat of the desert not far behind. Oregon and Washington then usher in the Cascade Mountains, which are considered a temperate rainforest. Desert to glaciers to rainforest. That is radically different than the green tunnel syndrome on the AT.

2. Climate Changes

Having so many different types of terrain on the PCT also means having to adapt to more extreme changes in climate while hiking. The desert is blistering hot during the day and but temperatures drop significantly as the sun goes down. Snow pack in the Sierra Mountains is erratic and varies greatly between each year. Due to elevation changes, one can easily sleep in the valley every night, making contact with the dirt, and yet spend all day hiking through snow. The weather in the Cascades can be unpredictable at times. All of these elements leave you on your toes.

On the other hand, the AT usually does not have drastic enough changes in elevation as to have such a strong change in climate throughout a single day. Still, the changes in weather can bring about a wide range of possible situations on must be prepared for. The AT is notoriously more rainy than the PCT and in the mountains, a simple thunderstorm can easily come equipped with loads of lightening and large hail. Not a fun place to be taking in the views from a high ridgeline.

3. Gear Changes


PCT gear setup on the left, AT gear setup on the right. Note the crampons, ice axe and SPOT GPS in the PCT setup. These are items you usually don’t need on the AT.

Because of the changes in both climate and terrain, a change in gear is needed as a result. Items that are usually considered unnecessary on the AT become essential safety items on the PCT. An ice axe and crampons for the High Sierra are many times crucial to have. A GPS can mean the difference between guessing where the snow covered trail leads and knowing you are headed in the correct direction even if you see no trail below you. A bear canister is required while walking through most of the Sierras.


On the AT, the trail is very evident unless an uncharacteristically heavy snow has fallen and while crampons are a very helpful at times, carrying a tool such as an ice axe for self-arrest is over doing it. Generally speaking, thru hikers on the PCT go to extreme lengths to cut down on their pack weight. While counting ounces is important on the AT, most typical AT packs weights are more than that of what you would see on the PCT. Even the most popular packs on the PCT are themselves from ultralight brands such as Gossamer Gear and ULA instead of Osprey or Gregory, as seen on the AT. Still, gear choices always vary heavily from one hiker to another.

4. Technical Changes

Not only does the extended length of the PCT (500 miles longer than the AT!) change the way you approach the trail technically, but the way the trail is graded does as well. On the PCT, you essentially have the same amount of time (six months) to put down more miles (just under 2,700 as opposed to just under 2,200) than on the AT. This calls for higher mileage days on the PCT than most consistently keep up on the AT. But the PCT is graded for pack mules, whereas the AT was built with no such intentions. This means many of the climbs on the PCT are not as brutally steep as on the AT. Though, keep in mind those miles in the High Sierra, you are crossing those mountain passes at a time when pack mules would be steering clear. “Graded for pack animals” is to be taken as seriously as “Virginia is flat”. It in no way translates into “cake walk”. The PCT also requires a fair amount more mandatory planning, mostly in regards to mail drops. On the AT, there are several places along the trail at which it would be advantageous to send yourself a mail drop, but not totally necessary. On the PCT, hitches into town are longer and less populated, making mail drops a more vital part of resupply than on the AT.

Don’t Forget The Similarities!!


You will experience beautiful places with wonderful humans and share the joy of the hiker trash lifestyle with all you meet!!

It’s a thru hike. It’s going to be hard. You’re going to fall in love with it and hate it at the same time. You’re going to stink really badly and get sun burned and be starving for months on end. You’re going to meet other hikers who become closer to you than your blood kin. You’re going to meet strangers who provide you with what you needed exactly when you needed it just because they have the ability and heart to do so. You’re going to struggle and hurt and fret and want to quit and you’re going to fight and work hard and over come. You will be scared and you will laugh. Just as with the AT, you will attempt, you may conquer, and you will be a more beautiful human for it.

Other Hikers, Weighing In:

In gathering all this information, I mainly spoke with thru hikers of the PCT whom I have met or were referred to from AT hiker pals. Personal experience of others helped me the most in preparing for the AT so I applied that technique here. Of the hikers I spoke with, those who have thru hiked both trails seem to agree that the PCT is physically easier despite the higher mileage days. They also agreed that the PCT is more mentally taxing than the AT. The AT is more draining on the body but the social aspect and more consistent trips into town keep the mind and spirit healthy. The PCT has a way of wearing down the mind before the body, but all the hikers said that the beauty of the PCT was much greater and more inspiring than the AT.

One Last GREAT Resource:

AIH PCT Banner

Real life AT thru hikers turned real life PCT thru hikers, Andy Laub and Ian Mangiardi, made a stellar documentary following their thru hike of the PCT in 2011. As It Happens is visually beautiful, tells the honest story of a thru hike and also inspires all who watch it.  Ian and I spoke at length during my information gathering period and he helped shed light on much of the above content despite a busy life full of things that are much more interesting than talk to me. He is the Expedition Manager for his own company  (Modern Explorer, Inc.) and has been recently working with the royal family of Bhutan on a fascinating project that combines wilderness expeditions with an incredible personal look into the culture of Bhutan. He’s a gentleman and a scholar and a pretty interesting dude, too! Thanks for the help, Ian!

    PCT thru hike is nothing but joke. Just do the AT or take a hike. No matter how many times you do PCT thru hike, you are still a loser. AT is the only way to know “what is hike”.

    • ZZ : Feb 5th

      That comment is very inappropriate. Every trail is meant for different people and different accomplishments. There is no “only” hike. Every through hike no matter how long or were is a personal accomplishment and whatever hike you hike you should be proud of yourself to not just take the time but to get out of your personal comfort zone and leave everything behind. Experiencing different states of emotion and physical challenges. It doesn’t matter how long or where you hike every hike is a personal accomplishment and should never be judged.

    • Ranger : Mar 7th

      Hike your own hike like we say on the AT. Every trail is different and wonderful if your mind is right. A good man named Nimblewill Nomad’s hiked them all BTW. Happy Trails

    • Marce Branniff : Mar 8th

      I’ve done both. You clearly haven’t. Go away, troll.

    • andre : Mar 12th

      Pacific Crest Trail and the Appalachian Trail are easy trails for us Europeans who are accustomed to hike in the Alps and Pyréenés. Really no need to do it proud with the Appalachian Trail.
      I invite you to come to the GR10, GR11 and the HRP. The climbs are steeper than on Appalachian Trail.

    • Robert H Nation : Oct 25th

      Hike your own hike.

    • VexedWeasel : Jul 4th


  • Tom Kennedy : Oct 25th

    If you want to hike do the PCT. If you want to rock climb, do the AT

  • Paul Wylezol : Dec 29th

    There is a 5th difference as well. The AT leads to the IAT, the International Appalachian Trail, which extends from Mount Katahdin, Maine through eastern Canada to Greenland, Iceland, Scandinavia, Scotland, Ireland, Wales, England, Spain, Portugal and Morocco. There is no IPCT.

  • Paul Boulay : Mar 7th

    The International Appalachian Trail adds about 600 miles from Baxter State Park in Main to the shoreline at the end of the Gaspe Penninsula in New Brunswick, Canada. I did the AT in ’78-’79, but I would love to finish that route with thi IAT. The IAT was only an idea; nothing was on the ground in 1978.

  • eddie : Mar 9th

    I’ll take “things white people do” for 1000 alex

    • mkt : Oct 23rd

      I’m “white” and I think your comment is hilarious!

  • Sheryl Savage : Mar 9th

    The AT is amazingly beautiful. I have done different parts of it. Never had the opportunity to do a thru…….maybe someday!

  • Alvin : Mar 22nd

    I have been planning to hike the AT for over 10 years. After many setbacks, postponements and vast disappointments, I finally set out in 2014 to do a NOBO of the AT. After 31 days on the trail I had to come off for several reasons including a knee injury and financial issues. Durin my 31 days on the AT, I found that the AT is truly a mystical and spiritual place. The people you meet on the AT, other hikers, trail angels and the like, all add to the special experience. There is something magical about the AT, and it draws you into it. Every experience I encountered was right on time.
    I am returning to finish the NOBO hike this year and leaving a few days from now. And I have been entertaining the idea to do the PCT after, and maybe make the triple crown.
    The brief differences outlined in the article seems challenging in their own way. So to begin again and continue to trek on … Here it goes. I plan to enjoy my hike and make my experiences an addition to my enriched Life no mater what the differences are among different trails. Each surely has something to experience in different ways. Experience all you can and enrich your life. Then share it. And don’t give up on your dreams.

    There is no IPCT (yet), but the PCT does connect to the Pacific Northwest National Scenic Trail (PNT) near the US-Canada border, which you can hike east on to its eastern terminus in Glacier NP and then go north on the Great Divide Trail (GDT) up through AB and BC almost to Prince George.

    So, another 1,500 or so miles of continuous hiking across the two countries.

    It is currently illegal to cross the border from Canada into the US on the PCT, due to US policy as there is no legal entry point there:

    So, until that is fixed, a thru and true IPCT can’t happen, but hopefully that will change:

  • Zod : Oct 25th

    First and foremost, hike your own hike! Don’t fall into the traps. Take a shuttle if you want, skip a trail if you like, or make sure you take every step of whatever trail you’re on if that makes you smile. It’s your time, life, and hike. Make sure it’s yours! These trails are very different from each other, but they both will change your life in the end. You really can’t go wrong. You’ll meet some of the best, and most amazing people of your life on either. Anyone who tells you one of these trails isn’t worthy is simply insecure about something. Don’t decide your trail on other people’s short comings. Decide it by what feels right for you. Hike your own hike!

      This was such a wonderful comment, I appreciate you taking the time to say it! A lovely way to end the comment thread. Thank you!
