Hermosa Roadless Area Profile
At a Glance: West of Highway 550 between Hermosa and Durango Mountain Resort, the Hermosa Roadless Area is the largest unprotected roadless area in Colorado encompassing one of Colorado’s largest and most biologically diverse forests, including at least 17 separate ecosystems ranging from rocky scrub oak and pinyon-juniper at lower elevations to aspen, spruce, and fir. Hermosa contains some of the largest stands of old-growth ponderosa pine remaining in the San Juan Mountains.

Threats: The Hermosa could be threatened in the future by energy development, and is currently threatened by motorized vehicle use. The current forest planning process is making determinations as to where energy development could take place in the future, as well as areas where motorized recreation is and is not allowed. In draft documents, the Hermosa Roadless Area east of the Hermosa Creek is being proposed as an opportunity area for motorized recreation. This means that new motorized routes may be created added to existing motorized routes. Additional trails could threaten water quality and lead to increased erosion, negatively impacting the ability of the area to filter and store water resources. More trails would also further impact wildlife and increase conflicts with other recreationists.

Adoption Duties for the Hermosa Roadless Area Include (but not limited to):

  • Engage is the management planning process for the San Juan Public Lands, advocating that the Hermosa not be an opportunity area for new motorized route creation (and further that existing motorized routes are not appropriate);
  • Engage in the travel management process, which will determine specific routes that will be legal motorized and non-motorized routes for years to come;
  • Get to know the area, monitoring any key routes where there are resource issues. Submit information gathered to the Forest Service.
  • Lead a hike or take your friends there so more people are connected to the place and interesting in protecting it.

Description:
The Hermosa roadless area encompasses one of Colorado’s largest and most biologically diverse forests, including at least 17 separate ecosystems, ranging from rocky scrub oak and pinyon-juniper at lower elevations to aspen, spruce, and fir. Tracts of virgin timber exist at elevations as low as 7,000 feet, well below the typical elevation of most protected forested areas in Colorado. In fact, Hermosa contains some of the largest stands of old-growth ponderosa pine remaining in the San Juan Mountains.

Hermosa’s extraordinary ecological variety has compelled a proposed Research Natural Area covering approximately 26,000 acres of Hermosa Creek’s western tributaries, centered on Buck Creek and Hope Creek. This RNA provides representation of exceptionally varied mixed-conifer forests containing Douglas-fir, white fir, aspen, blue spruce, ponderosa pine, southwestern white pine and Gambel’s oak. Extensive stands of old-growth spruce-fir occur at the highest elevations to complement the lower forests, and riparian communities in excellent condition occur throughout.

The 162,965-acre Hermosa Roadless Area has been managed to retain its wild character since the 1970s Roadless Area Review and Evaluation (RARE) studies. Current management plans perpetuate Hermosa’s undeveloped backcountry values by prohibiting logging and mining. This primitive management emphasis was the result of a public advisory committee convened by the Forest Service in the 1970s. Mountain bicyclists discovered Hermosa in the 1980s, however, and the main Hermosa Creek trail now serves as one of the most popular and scenic mountain bike routes in Colorado. The undeveloped Hermosa watershed and dendritic drainage pattern offers extraordinary opportunities for backcountry treks and in this respect provides a positive alternative to heavily-used routes in nearby wilderness areas such as the Weminuche. More than 125 miles of trails lace through the roadless area. The extremely popular Hermosa Trail is presently open to all forms of backcountry recreation, including hiking, horses, mountain bikes, motorcycles, and ATVs. Ten tributary trails branch from the main Hermosa Trail and offer access to numerous more remote valleys.

Hermosa Citizens Wilderness Proposal
A portion of the Hermosa Roadless Area has been found eligible for Wilderness designation and proposed as such in the Citizens Plan for the Wild San Juans. More information link to wilderness hermosa page.
