Hermosa Creek Wilderness, Protected wilderness zone in San Juan National Forest, Colorado.

Hermosa Creek Wilderness is a 37,236-acre U.S. Wilderness Area in La Plata County, Colorado, 12 miles north of Durango in the San Juan National Forest. Sedimentary beds of the Paleozoic Molas and Hermosa formations underlie most of it, capped along Indian Trail Ridge by Jurassic Dolores Formation rocks. Elevation runs from 7,500 feet on Hermosa Creek to 12,338 feet on the ridge.

The Hermosa Creek Protection Act of 2014 established the wilderness and created the adjacent Hermosa Creek Special Management Area, which shares its eastern border along Hermosa Creek. The area lies in the San Juan National Forest, 12 miles north of Durango in La Plata County, Colorado.

Hermosa Creek takes its name from the Spanish word for "beautiful." The wilderness lies within the San Juan National Forest, and the adjacent Hermosa Creek Special Management Area, created by the same 2014 act, shares its eastern border along Hermosa Creek. Visitors on foot or horseback can follow the Salt Creek and Clear Creek trails, which descend from headwaters on the western border to Hermosa Creek.

Two main trails, Salt Creek and Clear Creek, serve as the primary access routes for hiking and horseback travel through the landscape. Visitors should prepare for changing mountain weather and bring appropriate gear, as the terrain is steep and exposed in many areas.

The wilderness was only weakly glaciated, so it lacks the glacial features common elsewhere in the San Juan Mountains; along the eastern side of Indian Trail Ridge, subtle cirque shapes are the only trace. Its sedimentary beds also lack the volcanic lavas and tuffs found in neighbouring ranges.
