Long Distance Trails

Hiking the Spine of North America: A Journey Along the Continental Divide Trail

POSTED ON September 13, 2023 BY Ralph S.


If you’re a hiker or a trail runner who’s eager to take your experience to the next level, you shouldn’t miss the opportunity to explore the Continental Divide Trail (CDT).

For adventurers seeking a true expedition, thru-hiking the Continental Divide Trail is an unforgettable experience. This trail is one of the most challenging long-distance hikes in the world, featuring extreme temperatures, high-altitude conditions, and rugged terrain. It takes an average of 6-7 months to complete and is divided into five sections: New Mexico, Southern Colorado, Wyoming, Idaho, and Montana.

Stretching about 3100 miles (4988 km), the CDT passes through some of North America’s most spectacular terrain – including the Rocky Mountains and the Wind River Range – as well as through seven National Parks: Glacier National Park, Yellowstone National Park, Canyonlands National Park, Great Basin National Park, Rocky Mountain National Park, and Arapaho National Forest. While much of the route is off-road, some sections require road walking or hiking on official CDT routes.

The CDT is part of the Triple Crown of long thru-hikes, which also includes the Appalachian Trail and Pacific Crest Trail. For many hikers, completing all three is a dream come true – but no matter what your goal is, traversing the CDT will be an adventure you won’t soon forget.

From the desert of Southern Colorado to Wyoming’s high San Juan Mountains, the miles and terrain vary as much as the amazing views on either side of the divide.

For those who are willing to take on the experience, you’ll be rewarded with a sense of accomplishment like no other when you reach the other side of town for that well-deserved burger.

The history of the CDT is a tale of collaboration between the Continental Divide Trail Coalition, the National Park Service, the Forest Service, and other entities. Their efforts have transformed the CDT from a patchwork of trails and road walking into an official long trail.

In the early years, tackling the CDT was an audacious undertaking with few resources available. As the trail gained recognition, hikers established the “main CDT” and set the standard for what a long-distance trek entails. Town stops, strategically positioned along the route, offer resupplies and a chance to rest.

The CDT not only showcases the continent’s backbone but also provides an avenue for personal growth, as adventurous people find themselves facing challenges and redefining their limits. From the southern deserts to the northern peaks, the CDT promises an extraordinary long-distance adventure—an expedition of self-discovery amidst breathtaking landscapes.

Hiking the CDT is an adventure like no other. Comparable to the Pacific Crest Trail (PCT) and the Appalachian Trail (ATl), completing the CDT is part of the Triple Crown of thru hiking and is also considered to be the most challenging of the three. Hikers tackle extreme challenges as they traverse the trail, from desert stretches to high alpine climbs. The CDT’s official route often diverges from marked trails, providing a unique and rewarding experience.

The trail passes through iconic spots such as Glacier National Park, offering unparalleled beauty. Hikers encounter remote sections where navigation skills are paramount.

The path often leads off the beaten path, requiring self-reliance and an indomitable spirit. It is recommended to tackle the AT or PCT first on your thru-hiking adventure to become a triple-crowner.

Trail Overview: Difficulty Levels and Route Options

Hiking the Continental Divide Trail is a thru hiker’s dream come true. With 3,100 miles (4,988 kilometers) spanning from Mexico to Canada, the CDT is an epic adventure that coincides with the Colorado Trail and crosses through seven national parks and four states: New Mexico, Colorado, Wyoming, and Montana.

Formed in 1978 by the Continental Divide Trail Coalition (CDTC), it follows the backbone of North America and is part of the Triple Crown of long-thru hikes.

The CDT passes through some stunning landscapes. You’ll find yourself walking along dirt roads in the deserts, scaling high peaks in the Rocky Mountains, and meandering through peaceful forests in Colorado’s Grand Lake.

Depending on which section you tackle, the terrain and route options vary. Most hikers start in Mexico and move north towards Canada, though the opposite route is also possible.

The CDT is an experience that requires physical fitness and mental toughness. The elements of bad weather, long miles, and remote wilderness can make it difficult to complete the trail in one go. This usually means that most adventurous people choose to section hike the CDT, breaking it up into more manageable chunks. You can read more information about the challenges of mountain hiking in our guide to help you plan a successful trip.

To complete the trail in full, you’ll need to plan your route carefully and prepare for long distances between supply points. You also need to be well stocked up on food carries – this is especially true if you’re venturing off official CDT routes onto trails or gravel roads.

For those who are willing to take on the challenge, there is an amazing sense of accomplishment when you reach the other side. Hiking the entire Trail will be a life-changing experience that you’ll never forget. The pain, exhaustion, and joy of reaching a new peak will stay with you forever.

The CDT allows thru hikers to immerse themselves in a completely new environment and experience the beauty of nature in its rawest form. You’ll build relationships with fellow hikers, share stories, and make memories that will last for years to come. Every day brings fresh opportunities to explore the mountains and uncover hidden gems you couldn’t have hoped to find any other way.

With preparation, a lot of drive, and dedication, you can make your dreams of hiking the CDT a reality. However, it is recommended to gain some thru-hiking experience before attempting a CDT thru-hike.

Preparing for the Trail: Physical and Mental Fitness

Preparing for the Continental Divide Trail is essential to ensuring a safe and successful hiking experience. Not only are you required to have an adequate level of physical fitness, but also mental readiness – as pushing yourself out of your comfort zone in terms of landscape, weather conditions, altitude change, and isolation from society can be daunting. Here’s a guide to help you prepare for the challenges of desert hiking and hiking in the rain.

The most important aspect of preparing for the CDT and other long-distance hiking is getting your body used to high-altitude trekking. Altitudes can range from 4,200 feet (1280 meters) at the border of Mexico and New Mexico up to 14,278 feet (4351) at Grays Peak in Colorado – so it’s essential that you train your body accordingly. You can check out how to get in shape for hiking.

Additionally, the cost of thru-hiking the CDT should not be overlooked. The cost of food, gear, and accommodation needs to be factored into your budget. To help you plan ahead, make sure to check out our guide on the cost of thru-hiking for an idea of how much you should budget.

Microclimates on the trail will vary drastically, from desert landscapes with sweltering heat to snow-covered mountains with freezing temperatures. Training your body for the conditions you will face on the CDT is of utmost importance, as altitude affects your heart rate and breathing – not only slowing down your pace but also making you feel weak when exerting yourself.

Mental preparation is even more important than physical training for long thru-hikes like the CDT. As the trail is so remote, you will spend a lot of time alone and in solitude – so it’s important to have a plan to cope with such scenarios. Many people find that keeping a journal or writing blog posts helps them stay focused throughout their trek. Additionally, having regular contact with friends and family can provide a sense of reassurance while on the trail.

The CDT is not for the faint of heart – but with plenty of physical and mental preparation, you can embark on a tour of self-discovery like no other. The rewards will be plentiful – as pushing yourself out of your comfort zone and conquering ever-changing landscapes will be an unforgettable experience.

  • You can read books about the CDT, and check out resources from the CDTC. Here are two helpful guides [1] [2]
  • Leave yourself plenty of time so you can savor each and every moment
  • Choose the right gear for your trek: You’ll need to understand what to pack for a multi-day hike. But lightweight is key.

Seasonal Considerations: Best Times to Hike The Continental Divide Trail and Weather Conditions

Hiking the full length of the Continental Divide Trail (CDT) is a remarkable thru-hike that takes you through a diverse range of climate conditions. With support from the Continental Divide Trail Coalition, the National Park Service, and other entities, the CDT offers an incredible cruise, much like the more accessible and popular Appalachian Trail.

Here are the seasonal considerations and best times to visit.

Spring (March-May)

As thru-hikers begin their trek, they’ll experience the transition from winter to spring. Days in the wilderness can be warm, ranging from 15-25°C (59-77°F), but nights can still be chilly, dropping to 0-10°C (32-50°F).

As you head north, temperatures can be unpredictable, with sudden snowstorms and rapidly changing conditions in the Rocky Mountains.

Summer (June – August)

Thru-hikers reach high altitudes and encounter various microclimates. In areas like the San Juans, the temperatures can range from a comfortable 10-20°C (50-68°F) during the day, but they can drop dramatically at night.

The Northern Rockies, including Glacier National Park, offer milder daytime temperatures around 15-25°C (59-77°F), but nights can still get quite cold.

Fall (September – November)

As fall arrives, hikers heading toward the Canadian border can face dropping temperatures, especially in high alpine areas. Expect daytime temperatures around 10-20°C (50-68°F), but prepare for colder nights ranging from -5 to 5°C (23-41°F).

In Montana’s Bob Marshall Wilderness and Wyoming’s Wind River Range (location), snowstorms are a possibility.

Winter (December – February)

Winter hiking on the CDT is a serious challenge and not recommended for most beginner hikers. The route is often covered in deep snow, and conditions can be treacherous. Temperatures can plummet well below freezing, ranging from -20 to -5°C (-4 to 23°F), making even short sections extremely dangerous and should only be attempted by groups of people with a lot of experience in similar conditions. 

Thru-hiking the CDT demands careful planning. Always be prepared for sudden changes and bad weather, especially at high elevations. Fortunately, there are rest towns along the way that can provide a break from challenging conditions.
