Colorado Trail

The Colorado Trail is a long-distance trail running for from the mouth of Waterton Canyon southwest of Denver to Durango in Colorado, United States. Its highest point is above sea level, and most of the trail is above . Despite its high elevation, the trail often dips below the alpine timberline to provide refuge from the exposed, storm-prone regions above.
The Colorado Trail was built and is currently maintained by the non-profit Colorado Trail Foundation and the United States Forest Service, and was connected in 1987.
Description.
The Colorado Trail is an established, marked, and mostly non-motorized trail open to hikers, horse riders, and bicyclists. From the eastern terminus at Waterton Canyon, southwest of Denver, the trail winds its way for through the state's most mountainous regions, to its final conclusion, about north of Durango. Along the way, it passes through eight mountain ranges, six National Forests, and six wilderness areas.
Trail elevations range from a low of about at the Denver end of the trail to a high of on the slopes of Coney in the San Juan Mountains. The trail rises and falls dramatically. A hiker traversing the entire length of the trail will gain (and lose) about 89,000 vertical feet. The trail passes through what is considered to be some of the state's most beautiful country. Wildlife abounds and wildflowers, in season, are abundant. While much of the trail passes through forests, a good portion of it reaches above timberline, where trees are unable to grow and views are breathtaking.
The trail passes through historic mining towns, along ancient Native American trails, and through a modern, world-class ski resort. Other sections appear much as they would have 500 years ago. The western half of The Colorado Trail, between Monarch Pass and Durango, has less human influence, greater vistas and a display of spectacular wildflowers.
For , The Colorado Trail runs concurrent with the Continental Divide Trail along the Collegiate East route. On the Collegiate West route, the Colorado Trail follows the Continental Divide Trail for more.
Weather.
Summer days are warm with cool nights, but unpredictable mountain weather can threaten snow any month of the year. Violent thunder and lightning storms may ravage the afternoon sky, then quickly give way to warm sunshine and cloudless skies.
The practical season for the entire Colorado Trail is roughly July, August and September, though low elevation portions near Denver are often accessible April through June. In the winter, large parts of it are prohibitively difficult because of deep snow.
Thru-hiking.
The majority of thru-hikers (those who hike the entire trail in one trip) hike from east to west. This choice of direction is preferred partly because snow typically melts earlier in the year on the eastern portion of the trail than on the higher western portion. In addition, the east-to-west hike allows a thru-hiker to start with more gradual elevation gains and build up to the more rugged terrain of the western portion of the trail in the San Juan Mountains.
The time required for a thru-hiker to complete the Colorado Trail varies greatly. While some supported trail runners can finish it in less than 10 days (the unsupported fastest-known time is 9 days, 12 hours and 32 minutes by John Zahorian), most thru-hikers spend about 4 to 6 weeks (28 to 42 days) on the trail.
Mountain biking.
The Colorado Trail is one of the few major long trails that allow mountain biking. Mountain bikes are permitted along most of the trail, but there are six wilderness areas where it is against federal regulations even to possess a bicycle. As a whole, the trail is of interest to bicyclists from beginners on up. Top cyclists consider it to be a world-class long-distance trail.
Colorado Trail Foundation.
The Colorado Trail Foundation, based in Golden, Colorado, is a nonprofit organization that operates and maintains the Colorado Trail. Assisted by 600 volunteers and 3,000 donors each year, the CTF maintains over 500 miles of trail. Each summer, its trail crews work for about 12 weeks and six weekends clearing trees, working on erosion controls, and maintaining signage along the trail. The trail crews work on major projects that are beyond the scope of its sister "Adopt-A-Trail" program. That program lets interested volunteers "adopt" one of 78 maintenance sections along the trail, each averaging about eight miles long.
Every summer, the CTF offers week-long supported treks on the Trail, providing hikers with guides and the services of the trekking staff.
The Foundation maintains an extensive web site with information about the trail, and publishes a series of books and trail guides for hikers.
Governance.
The CTF is governed by a twelve-person board. There is a full-time Executive Director and one administrative staff member. Its total revenues in 2013 were just over $400,000.
History.
The Colorado Trail was conceived in 1973 by the Roundup Riders of the Rockies, but not connected end-to-end until 1987. The Colorado Trail Foundation (CTF) evolved out of cooperative efforts by the United States Forest Service, the Colorado Mountain Trails Foundation, and individual volunteers from the Colorado Mountain Club and the Friends of the Colorado Trail. In 2005, a Memorandum of Understanding was signed by the CTF and Forest Service, detailing their respective roles in the future development of the trail.
