A Seasoned Hiker’s Guide to the 3 Most Iconic Trails in the U.S.

Few long-distance hikes capture the imagination like the Appalachian Trail (AT), Pacific Crest Trail (PCT), and Continental Divide Trail (CDT). These epic routes stretch across thousands of miles, showcasing some of North America’s most stunning deserts, mountains, and forests.

Each trail offers unique challenges and rewards for those brave enough to take them on. Thru-hikers face unpredictable weather, intricate logistics, and the physical demands of trekking thousands of miles—often living in the wild for weeks or months. Completing any one of these trails is a significant achievement, but those who successfully finish all three (around 700 individuals recognized by the American Long Distance Hiking Association – West) earn the prestigious title of Triple Crown hikers.

Liz Thomas, a Triple Crowner who once set the record for the fastest female thru-hike of the AT, is currently the editor-in-chief of the hiking website Treeline Review. She provides Dinogo readers with valuable insights into each trail and highlights some must-see segments.

Appalachian Trail

Ideal for: those new to long-distance hiking

The Appalachian Trail is a footpath that spans roughly 2,200 miles along the Appalachian Mountain Range in the eastern U.S. It starts at Springer Mountain in Georgia and concludes at Mount Katahdin in Maine, crossing 14 states and 75 federal and state forests and parks, primarily winding through forested areas along the mountains, from oak-hickory to northern hardwood forests.

Thomas recommends this trail for beginners as it is the shortest of the triple-crown routes and often passes through towns (such as Damascus, Virginia, and Duncannon, Pennsylvania), where hikers can resupply and fix their gear.

“The Appalachian Trail fosters a sense of community, allowing hikers to connect with others along their journey,” Thomas remarked. “It tends to be busier, but that means there are plenty of people available to assist you.”

Those who aspire to traverse the entire trail in one continuous stretch usually spend between five to seven months completing it. However, the AT is also popular for section hiking, where adventurers tackle portions of the trail over multiple years. According to Thomas, this approach can help alleviate trail congestion.

Must-see locations along the Appalachian Trail

Thomas highlights a remarkable segment through the Great Smoky Mountains National Park, offering hikers breathtaking views of fog-laden valleys and lush hemlock forests. Another favorite of hers is the White Mountains in New Hampshire, where daring hikers face steep and challenging terrain that demands solid scrambling abilities.

“Much of the AT is enveloped in what’s known as a ‘green tunnel,’ surrounded by trees,” Thomas explains. “However, reaching the White Mountains rewards you with broader vistas. Additionally, the Appalachian Mountain Club operates a hut system in that area, providing many backpackers the chance to rest in a bed and enjoy dinner, which is quite a treat on such a lengthy trek.”

Pacific Crest Trail

Ideal for: stunning scenery

The Pacific Crest Trail spans roughly 2,650 miles along the western coast of the United States, starting in Campo, a quaint town at the U.S./Mexico border, and journeying north through California, Oregon, and Washington, ultimately concluding in the Pasayten Wilderness near the U.S./Canada border.

Hikers journey through the arid landscapes of the Mojave Desert and the majestic heights of the Sierra Nevada and Cascade ranges, passing by 7 national parks, 26 national forests, 5 state parks, and 4 national monuments along the way.

“The PCT offers expansive views,” Thomas remarks. “The scenery throughout the entire trail is truly exceptional.”

Those who wish to complete the entire PCT in one season usually begin their journey in spring and wrap up in the fall. However, securing advance permits for the full route is necessary, with only 50 available each day, so prospective PCT hikers must plan accordingly.

Must-see locations along the Pacific Crest Trail

The PCT also provides numerous options for shorter day hikes and backpacking trips suitable for all skill levels. Thomas highlights popular sections, including the Southern California desert, known for its whimsical rock formations and towering cacti, as well as the snow-capped volcanoes and lush evergreen forests of Northern California's Cascade Range.

According to Thomas, the Sierra Nevada segment is the “true gem of the trail.” Spanning over 500 miles, this section boasts a highest elevation of 13,153 feet, where hikers conquer granite summits to discover alpine lakes and meadows adorned with wildflowers.

“This section is challenging due to the high altitude, but it also fosters a sense of community among hikers as you experience it together,” she notes.

Continental Divide Trail

Ideal for: hikers looking to challenge their skills

The Continental Divide Trail is the longest of the Triple Crown hiking trails in the U.S., winding approximately 3,100 miles through the rugged and remote landscapes of the Rocky Mountains. It traverses New Mexico, Colorado, Wyoming, Idaho, and Montana, offering stunning panoramic views of snow-capped summits and pristine mountain lakes.

In contrast to the PCT and AT, the CDT is not fully developed or maintained, requiring hikers to navigate a mix of established paths, dirt roads, and off-trail routes. This means relying on maps, compasses, and GPS devices, adding an extra level of challenge and adventure to the trek, demanding self-reliance and wilderness skills. On average, it takes about five and a half months to complete the entire trail in one journey.

“Most hikers opt to take on the CDT after gaining some trail experience because it’s so remote,” Thomas explains. “Having time on the other trails allows you to learn from your mistakes, which is crucial. The CDT isn’t forgiving for beginners, and if something goes wrong, getting help can be significantly more difficult. The stakes are higher.”

Must-see locations along the Continental Divide Trail

A notable section is New Mexico’s Gila Wilderness, spanning over 500,000 acres, where ancient cliff dwellings and hot springs are nestled among the desert mesas, as noted by Thomas. Another highlight is Montana’s Bob Marshall Wilderness, featuring river valleys and meadows teeming with herds of elk and mountain goats.

When the CDT presents its challenges, don’t give up—Thomas emphasizes that one of the trail’s greatest rewards is its conclusion in Montana’s Glacier National Park: “The trail wraps up at Waterton Lakes, which straddle the border between Canada and the U.S. You can stand on a dock and gaze out at this breathtaking mountain-framed lake, and it truly is something remarkable.”
