The unfinished wilderness trek spanning the spine of the American West

In short: Stretching from the Mexican border to the Canadian frontier, the Continental Divide Trail is a rugged test of endurance. Unlike its more famous counterparts, this path remains partially uncompleted, forcing hikers to navigate a mix of wild terrain, dirt paths, and paved roads across five different states.

The Continental Divide Trail (CDT) follows the Continental Divide of the Americas through Montana, Idaho, Wyoming, Colorado, and New Mexico. While the Continental Divide Trail Coalition measures the route at 3,028 miles (4,873 km), the actual distance hiked varies between 2,700 and 3,150 miles due to frequent re-routing and unfinished sections. As of 2021, the trail was approximately 70 percent complete, often requiring hikers to traverse roads to bypass gaps. The route follows the Rocky Mountains and can be accessed via the Great Divide Trail in British Columbia. In Montana, the path crosses Triple Divide Pass, where waters can flow into the Arctic, Atlantic, or Pacific Oceans.

This isolation makes the CDT a distinct challenge compared to the Appalachian or Pacific Crest Trails. In 2019, while over 1,000 people completed the AT or PCT, only 150 successfully finished the CDT. This difficulty is reflected in the 'Triple Crown' of long-distance hiking; since 1994, 837 hikers have achieved this feat by completing the AT, PCT, and CDT. The trail's extreme isolation is evidenced by the low number of successful thru-hikers compared to other major routes. This makes it a unique component of the prestigious Triple Crown of Hiking.

The journey is physically demanding and requires significant logistical planning. Thru-hikers typically spend about five months on the trail, averaging 147 days to complete the trek. Because the trail traverses remote areas, hikers must frequently hitchhike to towns for supplies or rely on 'trail angels'—volunteers who provide food, water, and transport. For those attempting the hike in high-altitude regions like the San Juan Mountains, impassable snow remains a primary obstacle. Hikers often encounter significant weather challenges, such as heavy snow in Glacier National Park. To manage the trek, many travelers utilize a passport for the Canadian border crossing.
