The 7 Hardest Day Hikes on the Appalachian Trail

Rate this story:

When I ask you to picture the mountains that span the Appalachian Trail, what comes to mind? Massive, majestic, daunting peaks?

Likely not—and you'd be right. It is for this reason that the uninitiated confuse the 2,189 miles (give or take, depending on the year) that make up the United States' original long trail as easy hiking. Some of it is. Most of it, however, is excruciatingly difficult.

In fact, of the three long trails in the United States (the Pacific Crest Trail, Continental Divide Trail, and Appalachian Trail), the AT offers the most elevation change on average. I've hiked all across the country, including the entire Appalachian Trail, Mount Whitney in California and several 14,000 footers in Colorado, and I can attest that the AT presents some of the toughest terrain in the country.

So if you're looking for a challenging day hike, you need not venture west to find it. Here are seven of the hardest day hikes on the Appalachian Trail.

7. The Priest

This hike is less than 9 miles round-trip but don't confuse its short distance with ease. The Priest showcases central Virginia's steepest climb with more than 3,000 feet of elevation gain over the 4.3-mile one-way trek (for those who start at VA56). To beef up an already challenging hike, park at the Crabtree Falls trailhead (a half-mile west of the AT) to hit the summit of the Priest, descend to the Tye River, climb to the summit of Three Ridges Mountain, and then back for a 24.6-mile round-trip haul.

Bonus fun fact: The trail log at the Priest Shelter also serves as a satirical-confessional, whereby hikers “confess their trail sins to the Priest.”

6. Lehigh Gap / Superfund Trailhead

If there's one word to associate with the Appalachian Trail in Pennsylvania, "steep" would not be it; the correct answer is "rocky.” Of the fourteen states the trail passes through, Pennsylvania is one of the flattest (not to be confused with fastest, again—the rocks). That's why countless hikers are caught off guard when they reach the Superfund Trailhead at Lehigh Gap, because what they're presented with is a 900-foot seemingly vertical rock scramble over the span of just three-quarters of a mile. Upon reaching the top of this climb and looking back at the Lehigh River below, you will forever have a worthwhile retort to those who speak of Pennsylvania's "flat" terrain.

5. Cheoah Bald

The anticipation of reaching Nantahala Outdoor Center in Bryson City, North Carolina—a hiker's paradise complete with a restaurant, bar and convenience store—has a way of overshadowing the climb that awaits to the north. And in this case, ignorance is bliss as the climb from the NOC to Cheoah Bald is not to be looked forward to unless you're a glutton for punishment. The nearly 3,000-foot ascent over 5.8 miles is followed by a 300-foot descent and then another 600-foot climb to reach this hike's destination, for a total round-trip trek of 15.8 grueling miles.

4. Mahoosuc Notch

Some refer to it as the most difficult mile of the AT, others the most fun. Anyway you shake it, Mahoosuc Notch is undeniably the trail's slowest mile. Navigating this gap in western Maine is the wilderness version of a jungle gym with more painful repercussions. Put your trekking poles away, because going up, over, under and between these massive boulders is an all-limb effort; beginners are encouraged to find a different hike. Finding your way here for a day hike can be a bit tricky; these directions are the best I’ve found.

3. Mount Washington

Likely the most notorious peak of the entire trail, Mount Washington cracks this list more for its weather than the difficulty of the climb, despite being the second-highest point of the AT at 6,288 feet. Located in the center of the Presidential Range in New Hampshire's White Mountain National Forest (simply referred to as "The Whites"), Mount Washington boasts arguably the most inclement weather on earth. For 76 years, it held the record for strongest wind gust, only losing that title to Australia's Barrow Island during Cyclone Olivia (at 253 mph) in 1996. It’s advisable to check the weather report at the nearby Lakes of the Clouds Hut before attempting a summit. Definitely bring rain gear, several layers, snacks and plenty of water. Be forewarned: Some of the luster of this climb is lost as you will be greeted by a massive parking lot, restaurant, gift shop and tourists at the summit.

2. Mount Katahdin

From the perspective of a northbound thru-hiker, the Appalachian Trail saves the most epic for last. That is to say, the trail's northern terminus, Mount Katahdin, is not only one of the most challenging ascents of the entire trail, it is also one of the most spectacular. This picturesque climb features the gorgeous Katahdin Stream Falls, a steep boulder field climb supported with metal rungs through Hunt Spur, and at nearly two-and-a-half miles above tree line, incredible summit views on a clear day. From your starting point at the Katahdin Stream Campground, the trail gains 4,162 feet in just 5.2 miles. Like most climbs in northern New England, prepare for the worst (i.e., harsh weather) and hope for the best.

1. Mount Madison

Perhaps overshadowed by its aforementioned Presidential Range brother to the south, Mount Madison offers one of the steepest, most challenging rock scrambles of the entire trail, gaining 2,812 feet over a 2.6-mile span (a more than 20% incline). The most feasible approach to this day hike is the southbound version, parking at the Joe Dodge Lodge at Pinkham Notch and following the Old Jackson Road to Madison Gulf to Great Gulf Trail to Osgood Cutoff to Osgood Trails, and then back for a total distance of 14.6 miles round-trip. The summit is well above tree line and offers stunning views of The Whites without all the fuss found at Mount Washington. Get an early start for this one.

    Excellent choices! Excellent descriptions! I remember them all – except Madison, somehow. Hmmm.

    • Walter E Daniels

      We took the blue trail around Madison as the top was being blasted by continuous lightening. Even that was tough because of the wind. We had to have a hiking stick so we had two points on the ground before taking a step, otherwise blown over.

    • I don’t remember Madison being difficult either — but I’m sure I would today (20 years later). I loved every day in the White Mountains — every day was awesome.

  • Michael Greene

    How did Washington and Madison make this list? The Priest needs to be moved up a notch as well.

  • Chuck Allen

    Madison might have been the toughest day on my thru hike. Good call.

    • Irina Rickard

      2 hours of tears lol definitely tough

  • James Adams

    Mahoosuc Notch is fun but the climb from there up the Mahoosuc Arm is also an incredible scramble. Can’t imagine that climb without thru hike conditioning.

    • Walter E Daniels

      I agree, one of our toughest sections. It just keeps going up with no distinguishing features to see out and tell how close to the top one is.

    • chango369

      Man that’s a fact! I couldn’t believe how steep and tangled that ascent was!

      As I was going up that section and heading for Speck Pond, I wasn’t feeling all that great. Little did I know that I was in the earliest stages of feeling the effects of having caught Giardia ( I think I got it before I even hit the Presidential Range).

      I didn’t get it fixed until I made it to Monson, when I was finally able get to a doctor and beg him for some Cipro.

  • Devon Hill

    My sister and I are planning a 4 week hike next Spring/Summer on the AT. Any suggestion on a good section for semi-beginners in the young 60 age range?? Thanks!

    • Victoria Ballestero

      108-miles in Shenandoah National Park- fairly easy and very accessible, plus okay views of the Blue Ridge Mountains and Piedmonts.

    • Stephen Hinzman

      97-98 miles starting at VA 621 in Craig County VA to the James River foot bridge would be a nice portion of your hike. You get the Audie Murphy Monument, Dragon’s Tooth, McAfee Knob (an iconic photo spot), Tinker’s Cliffs, Apple Orchard Falls (requires a side trip) and Apple Orchard Mountain with the FAA radar dome.

    • EVC

      Start with a couple of short easy hikes. After a couple, loaded packs. Load the pack like you would for the real thing. Keep the hikes challenging but not too crazy.

      Next, start doing overnighters of increasing length. Make sure to include some good steep climbs to condition your legs as best you can. These hikes should increase in difficulty and length but the first overnighter should be short and sweet. Just enough to test your gear if you haven’t aleeady.

      During your overnights, keep a log of the pack items you used as well as what you didn’t use. This way, you can continue refining the essentials. You’ll be amazed at what becomes “non-essential” after 15-20 miles.

      Grayson Highlands hands down. Where are ya’ll?

  • Did You Notice

    It’s Katahdin, not Mount Katahdin. Who wrote this? It reads like some intern spent ten minutes on Google.


      “Because “Mount Katahdin” literally means “Mount Greatest Mountain”, the mountain is commonly called just “Katahdin”,[5] including by Baxter State Park in official publications.[6] However, the official name is “Mount Katahdin” as decided by the US Board on Geographic Names in 1893″ (Spent like, 30 seconds, on google)

    Getting to the summit of Mount Washington from the Lakes hut is easy. Getting to the Lakes of the Clouds is the hard part.

  • Great list – I recall Lehigh Gap / Superfund Trailhead as the toughest, but that’s probably because it had been pouring rain for days and my water-soaked feet were being torn to shreds by all those rocks!

  • Giuseppie

    I’ve “only” hiked 460 miles of the AT, but I can emphatically attest to the difficulty of Cheoah Bald, and I vividly remember getting my ass handed to me on the day that I made the ascent. Making the top at sunset made it worthwhile, though I did press on, finishing in the dark.

  • Ashley Wilkins

    Now I wish you would make a list of 10 EASY day hikes on the A.T. because a back injury has sidelined my backpacking for a while but I still enjoy a good day hike.

  • thefarmhand

    Could you give me a little more information on the longer 24 mi. Priest/crabtree falls hike? I’d like to trek it in two weeks.

  • Ted Teodoro

    Looks like all of them will result in knee surgery

  • PJ McManus

    I did Madison and Adams last year, and it wasn’t as tough as Washington. I would put Washington higher up than Madison.

  • Jason_Viper

    The Priest (SOBO from Rt56) is legit. I go there often for training as it offers one of the best bangs for your climbing buck anywhere in the state.

  • ElliotCares

    Zach–fun article with good pictures….but I would put Kinsman Notch to Franconia Notch as #5 and Pinkham Notch (going north) to Gorham as #6. But I don’t know if you count these as “day hikes”. Maybe they’re actually just LFDs (Long &*#$@ Days).
