Rail-to-Trails Conservancy is non-profit organization focused on a nationwide network of trails built on former rail lines. In the 1980s the U. S. Congress became concerned about the loss of railroad infrastructure, thinking that some day in the future, the country may need to utilize this mode of transportation anew.  In an attempt to preserve these right-of-ways that crisscrossed the nation, they amended the National Trails System Act to create the "Railbanking" program. This is a method where unused rail corridors would be preserved for future rail use by converting them to interim public recreational trails.

Recent Supreme Court Legislation has created a setback for the concept of turning former rail line right-of-ways into public trails and communities may be forced to compensate land owners for the portion of land where the trail crosses. This 8-1 decision by the court could affect existing trails all over the country.

Colorado has many of these old rail corridors throughout the state that have been converted to public trails for pedestrian and cycling uses. These trails generally have very gentle grades and are a great way to see areas that were previously closed to the public.

Following is a list of the recreational trails located in Colorado that are one of the Rail-to-Trails Conservancy projects:

Rio Grande Trail - Glenwood Springs to Aspen

Running form Glenwood Springs to Aspen in the central mountains of Colorado along the beautiful Roaring Fork Valley, this 42 mile trail follows the abandoned railroad bed of the narrow gauge Rio Grande Railroad. The Rio Grande Railroad reached the silver mining town of Aspen in 1887. If you ride along this trail, you can still see some of the old rail lines, trestle bridges and rail cars. The development of this trail was highly contested by some of the local land owners, but the trail was constructed over 10 years ago. The trail is paved for the most part, but there is a section of gravel running from Woody Creek to Aspen.

Great Western Trail - Windsor, Severance and Eaton

This is an ongoing improvement project of a stretch of abandoned rail line that runs from Eaton, through Severence and onto Windsor. The raillines were constructed to support the farms and factories for the sugar beet industry in the early 1900s in Northern Colorado. The introduction of irrigation canals created a boom in the sugar industry with plants in Eaton, Windsor, Loveland and Longmont. This trail hooks up with the paved trail system for the Town of Windsor and is part of the growing regional recreational trail systems in Northern Colorado.
