The Big Three: America’s Most Iconic Thru-Hiking Trails
Not many brands can say they were born on the trail—figuratively speaking—like American Backcountry. Outdoorsman and hiker Frank Hintz transformed his love for America’s national landmarks into trail-ready apparel. It all began when he walked into the Appalachian Trail Conference headquarters back in 1993 with the first American Backcountry prototype, later debuting it at the annual Appalachian Trail Day Festival.
The response? An instant hit. Today, American Backcountry lets you show off your passion for the outdoors—and the trails you’ve conquered—in both style and comfort.
In this post, we’re highlighting the top three iconic thru-hike trails in the U.S. and what makes each one truly special:
The Appalachian Trail (AT)
Stretching over 2,190 miles through 14 states, the Appalachian Trail peaks at 6,643 feet atop Clingman’s Dome in Great Smoky Mountains National Park. If you’re hoping for an easy stroll, this might not be it—but everyone starts somewhere, right?
It’s famously tough: many who set out don’t finish, often due to injury, illness, or sheer fatigue. The first person to complete the trail was Earl Shaffer, a WWII veteran who said he wanted to “walk the army out of his system.”
Those who do finish usually take five to six months—logging roughly five million footsteps. Lightweight gear is essential; some hikers even ditch tents entirely, relying instead on the 250 three-sided shelters, or “lean-tos,” maintained by volunteers. If you want shelter but less bulk, a bivvy sack is a great compromise.

The Pacific Crest Trail (PCT)
Running roughly 2,663 miles from the US–Mexico border all the way to British Columbia, the Pacific Crest Trail traces the spine of the West Coast through California, Oregon, and Washington. The route crosses 25 national forests and seven national parks.At its highest point, Forester Pass in the Sierra Nevada, you’ll climb to 13,153 feet—nearly double the AT’s highest peak. The southern stretch challenges you with a 700-mile desert trek before reaching the lush Sierra Mountains, often the make-or-break section due to heavy snowfall.
Once past the Sierra, the trail reveals the stunning beauty of Northern California, Oregon, and Washington. The PCT is also known for its proximity to towns, meaning easier access to food, showers, and yes, beer.
For many, the PCT is a great introduction to thru-hiking—but don’t underestimate it. Proper research, prep, and gear—like American Backcountry’s UPF 50+ Pacific Crest shirt—are key for success.

The Continental Divide Trail (CDT)
The CDT is considered the most challenging of the big three—rigorous, remote, and rewarding. It runs along the Rockies through Montana, Idaho, Colorado, and New Mexico, covering somewhere between 2,500 and 3,100 miles depending on the route you choose.About 95% of the trail is public land, but it’s far less developed and marked than the others, with fewer town stops that tend to be pricier. The terrain is a mix of trails and paved roads, often above the treeline, and open to horseback riders.
Two main routes exist: the Continental Divide National Scenic Trail (CDNST), maintained by the Forest Service and generally easier and less remote; and the more rugged Continental Divide Trail (CDT) itself, which offers even more breathtaking scenery but demands higher skill and preparation.
Wildlife safety is crucial here—grizzly bears inhabit the area, though they usually avoid people. Carrying bear spray is a smart choice. And depending on when you hike, you might need an ice axe and crampons for snow and ice.

Final Thoughts
All three trails demand respect, research, and preparation. Talk to experts, plan carefully, but above all—have fun. The passion for adventure and respect for the wild is the foundation American Backcountry was built on. Who knows? Maybe your journey will inspire your own great idea out on the trail.
