What are the Big Three Hikes?
For many outdoor enthusiasts, the phrase "The Big Three Hikes" conjures images of epic journeys, breathtaking vistas, and a serious test of endurance. But what exactly are these legendary trails? While there isn't one universally agreed-upon, official list that every hiker on every forum will cite, the concept of "The Big Three" in American hiking generally refers to three of the most challenging, iconic, and longest thru-hikes in the United States. These are trails that demand months of commitment, extensive planning, and a significant amount of grit and determination. They are the Everest of long-distance hiking.
These three trails are:
- The Appalachian Trail (AT)
- The Pacific Crest Trail (PCT)
- The Continental Divide Trail (CDT)
Together, these trails are often referred to as the "Triple Crown of Hiking." Completing all three is an extraordinary achievement, a testament to a hiker's dedication and love for the wilderness.
1. The Appalachian Trail (AT)
Length and Location
The Appalachian Trail is the oldest and most popular of the three. Stretching approximately 2,190 miles, it winds its way through 14 eastern states, from Springer Mountain in Georgia to Mount Katahdin in Maine. It traverses some of the most beautiful and rugged mountain ranges in the eastern United States, offering a rich tapestry of forests, streams, and dramatic overlooks.
Difficulty and Experience
While often considered the "easiest" of the Triple Crown due to its well-established infrastructure and the sheer volume of hikers (meaning more support and camaraderie), the AT is by no means a walk in the park. It features relentless ups and downs, often referred to as "roller coasters," which can be incredibly taxing on the body. Hikers can expect steep climbs, rocky terrain, and unpredictable weather, including snow in the spring and fall, and hot, humid summers. The average thru-hike takes 5 to 7 months.
Key Features and Highlights
- Diverse Ecosystems: From the lush forests of the Smokies to the rocky peaks of New Hampshire, the AT showcases a remarkable variety of plant and animal life.
- Rich History: The trail is steeped in history, passing through Civil War battlefields and areas once traversed by early American settlers.
- Community: The AT boasts a strong and supportive hiking community, with numerous shelters, campsites, and trail magic (unexpected acts of kindness from strangers) along the way.
- Iconic Sections: Highlights include the Great Smoky Mountains National Park, the White Mountains of New Hampshire, and the rugged beauty of Maine.
2. The Pacific Crest Trail (PCT)
Length and Location
The Pacific Crest Trail is a more recent addition to the long-distance hiking scene, covering approximately 2,650 miles. It travels through California, Oregon, and Washington, from the Mexican border to the Canadian border. The PCT offers a stunning journey through diverse landscapes, from the scorching deserts of Southern California to the snow-capped peaks of the Sierra Nevada and the lush forests of the Pacific Northwest.
Difficulty and Experience
The PCT is renowned for its dramatic elevation changes, challenging water carries (especially in the desert sections), and the need for snow travel skills in the Sierras. Hikers must contend with extreme heat in the south, potential snowstorms in the mountains, and the unpredictable weather of the Cascades. The physical demands are immense, and the mental fortitude required is significant. An average thru-hike takes 4 to 6 months.
Key Features and Highlights
- Desert Beauty: The initial sections in Southern California offer a stark and beautiful desert landscape.
- The Majestic Sierra Nevada: This iconic mountain range presents breathtaking granite peaks, pristine alpine lakes, and challenging passes.
- Volcanic Landscapes: The trail winds through the volcanic regions of Oregon and Washington, showcasing dramatic mountain scenery.
- The Northern Terminus: Reaching the Canadian border is a triumphant moment, often marked by a celebratory photo at the Monument 78 trailhead.
3. The Continental Divide Trail (CDT)
Length and Location
The Continental Divide Trail is the wildest and most remote of the Triple Crown, spanning roughly 3,100 miles. It follows the Continental Divide, the imaginary line separating the watersheds that drain into the Pacific Ocean from those that drain into the Atlantic Ocean. The CDT journeys through Montana, Idaho, Wyoming, Colorado, and New Mexico, traversing some of the most undeveloped and rugged wilderness in the contiguous United States.
Difficulty and Experience
The CDT is characterized by its remoteness, lack of established trail for significant sections, and the need for advanced navigation skills. Hikers will encounter vast, undeveloped areas, challenging river crossings, and extreme weather, including snow that can persist well into the summer at higher elevations. The trail requires a high degree of self-sufficiency, route-finding ability, and preparedness for solitude. An average thru-hike can take 5 to 7 months, often longer due to the complexities of the route.
Key Features and Highlights
- True Wilderness: The CDT offers an unparalleled experience of solitude and immersion in pristine natural environments.
- High Alpine Scenery: The trail ascends to high mountain passes, offering panoramic views of the Rocky Mountains.
- Wildlife Encounters: Hikers are more likely to encounter large mammals like elk, bears, and moose in the wild expanses of the CDT.
- Challenging Navigation: Significant portions of the CDT are not officially marked trails, requiring hikers to rely on maps, compass, and GPS devices.
Why are they called the "Big Three"?
They are referred to as the "Big Three" because they represent the pinnacle of long-distance hiking in North America. These trails are not just about covering miles; they are about the transformative journey, the personal growth, and the profound connection with nature that comes from spending months immersed in the wilderness. Completing any one of them is a significant accomplishment, and completing all three is a rare and celebrated feat.
For the average American reader, understanding "The Big Three Hikes" opens a window into a world of extreme adventure, unparalleled natural beauty, and the enduring human spirit's capacity for perseverance. They are aspirations for many, and for a select few, they are conquered realities.
Frequently Asked Questions (FAQ)
Q: How long does it take to complete all three of the Big Three hikes?
Completing all three of the "Big Three" hikes is a monumental undertaking.

Many hikers dedicate multiple years to completing all three.
Q: Why are these specific hikes considered the "Big Three"?
These three trails are considered the "Big Three" due to their immense length, the significant logistical challenges they present, their iconic status within the thru-hiking community, and the profound physical and mental demands they place on hikers. They are widely recognized as the premier long-distance hiking challenges in the United States.
Q: Do you need special permits to hike these trails?
Yes, generally permits are required for hiking and camping on all three of the "Big Three" trails. The specific permit requirements vary by park, forest, and state along each trail. For example, you'll need permits for National Parks like Great Smoky Mountains or Yosemite, and often for specific wilderness areas. Planning and applying for these permits well in advance is crucial, as some can be highly competitive.
Q: What kind of physical condition do you need to be in to attempt these hikes?
You need to be in excellent physical condition. This means having a high level of cardiovascular endurance, muscular strength, and joint resilience.
