Continental Divide National Scenic Trail (Colorado Section)
The Continental Divide National Scenic Trail (CDNST) Colorado Section is a major portion of the longest scenic trail in the United States, stretching approximately 795 miles through Colorado from the New Mexico border near Antelope Peak to the Wyoming border at the Medicine Bow Mountains. It basically follows the Continental Divide—the hydrographic boundary separating Pacific Ocean–bound waters from Atlantic Ocean–bound waters. That makes it both a geographic and recreational centerpiece of the state. The Colorado section encompasses diverse terrain including high alpine meadows, forested mountain ranges, and arid plateaus, passing through or near numerous mountain ranges such as the San Juan, Rio Grande, Sawatch, and Laramie ranges. The U.S. Forest Service and Bureau of Land Management manage it cooperatively. Backpacking, day hiking, and horseback riding draw visitors year-round. It's also a critical corridor for wildlife migration and ecological connectivity. The Colorado portion represents roughly one-third of the entire 3,700-mile Continental Divide National Scenic Trail that extends from Canada to the Mexican border.[1]
History
Congress established the Continental Divide National Scenic Trail in 1978 as part of the National Trails System Act, recognizing the significance of the Continental Divide as both a natural landmark and recreational resource. Planning started in the 1980s. Various federal agencies and volunteer organizations collaborated to identify routes and construct or improve existing pathways. Early sections often followed established routes including portions of historic trade routes, mining roads, and pre-existing recreational trails that had evolved over decades. Substantial attention arrived during the 1990s and 2000s as funding came through the USDA Forest Service's trail development programs and partnerships with nonprofit organizations dedicated to scenic trail conservation and maintenance.
Volunteer effort shaped the modern trail in Colorado. Organizations such as the Continental Divide Trail Coalition, founded in the 1990s to promote and maintain the trail system, didn't work alone. They partnered with federal land management agencies to address maintenance issues, improve trail markings, and document accurate route information for hikers and recreational users. Trail development reflected broader American conservation priorities during the late twentieth century, emphasizing preservation of scenic landscapes and creation of long-distance recreational corridors that could accommodate diverse user groups while minimizing environmental impact. Colorado's central role in North American geography and hydrology positioned the state as a crucial link in the larger continental trail system.[2]
Geography
The Colorado section traverses remarkable geographic zones and elevations, ranging from approximately 7,000 feet above sea level in some southern sections to over 13,000 feet in high alpine areas near the San Juan Mountains. The trail's northern terminus enters Colorado near the New Mexico border in the San Juan Mountains region, one of Colorado's most rugged and remote mountain ranges. From there, it extends northeastward through the Rio Grande National Forest, crossing numerous peaks and passes that form the fundamental geographic feature—the hydrographic divide separating eastern and western water systems. Several major national forests host the trail including the San Isabel, Pike, and Roosevelt national forests, as well as significant portions of Bureau of Land Management property in western Colorado.
Southern Colorado sections wind through alpine terrain characteristic of the San Juan and Rio Grande ranges, featuring glacially-carved valleys, talus fields, and subalpine forests dominated by spruce and fir species. Moving northward through central Colorado, it crosses the Sawatch Range, which contains numerous peaks exceeding 14,000 feet in elevation, locally known as "fourteeners." This region involves significant elevation gains and losses, challenging even experienced backpackers while offering panoramic views of Colorado's highest mountain peaks. Northern sections cross the Rawah Wilderness and other high-elevation terrain before reaching the Wyoming border, maintaining elevations typically between 10,000 and 12,000 feet throughout much of the northern section. The diverse geology underlying the trail includes Precambrian granite and metamorphic rocks in many areas, Paleozoic sedimentary sequences in lower elevations, and more recent glacial deposits that shape the contemporary landscape.[3]
Attractions
Numerous natural attractions and points of interest draw recreational users throughout the year. The trail passes near several major Colorado peaks including Mount Elbert, Colorado's highest mountain at 14,440 feet, and other prominent summits in the Sawatch Range that serve as scenic viewpoints and destinations for day hikers accessing the trail. Many sections intersect with other popular hiking destinations and wilderness areas, allowing users to construct diverse itineraries combining the CDNST with side trips to lakes, peaks, and scenic valleys. Alpine tundra habitats provide opportunities for observing Colorado's unique high-elevation ecosystems, including specialized plant communities and wildlife species adapted to extreme environmental conditions.
Alpine lakes abound. They're particularly numerous in the central mountain regions where glaciation created distinctive basin features. The trail provides access to panoramic vistas overlooking major river valleys including the Rio Grande, Arkansas River, and Platte River drainages, offering hikers comprehensive views of Colorado's diverse mountain landscape. Several sections pass through areas of significant historical interest, including remnants of mining operations from Colorado's nineteenth-century mineral booms and historic trading routes used by indigenous peoples and early European explorers. Wildlife viewing opportunities are outstanding, particularly in sections passing through habitat supporting elk, bighorn sheep, mule deer, and various bird species including raptors and ptarmigans adapted to high-elevation environments. Multiple trailheads mean visitors can experience sections ranging from day hikes suitable for families to multi-week backpacking expeditions for experienced outdoor enthusiasts.[4]
Transportation
Access relies on a combination of vehicle transportation to trailheads and pedestrian/equestrian movement along the trail itself. Primary access routes to southern Colorado trailheads use highways including U.S. Route 550 and Colorado State Route 285, which provide vehicle access to parking areas and trailheads serving the San Juan and Rio Grande mountain sections. Central Colorado sections are reached via U.S. Route 24, Colorado State Route 82, and various Forest Service roads that extend into the mountains from valley communities including Leadville, Salida, and other gateway towns. Northern Colorado sections are reached from Fort Collins, Estes Park, and Jackson via routes providing access to the Rawah Wilderness and Medicine Bow Mountain regions.
It accommodates multiple modes of non-motorized transportation. Hikers, backpackers, and horseback riders can travel the majority of the route. Certain sections permit stock animals including horses and mules, making the trail popular with outfitters offering guided pack trips and backcountry expeditions. Regular maintenance clears obstacles and maintains water bars and drainage features to control erosion and keep hiking conditions good. Many Colorado communities located near the trail have developed services supporting CDNST users, including outfitters, backcountry equipment retailers, and accommodations catering to pre- and post-hike stays. Numerous spur trails and connector routes allow users to access the main trail from various trailheads, and several trail towns along the CDNST corridor provide resupply opportunities for long-distance hikers undertaking multi-week journeys.
