Mt. Sneffels Wilderness

Posted: May 10, 2011 by Sam Szarka

The views south of Ridgeway are considered to be some of Colorado’s most captivating scenes. Mt Sneffels, Dallas Peak, and their neighbors rise in a spectacular fashion from the Uncompahgre valley below. Large, scenic ranches line the northern slopes of the Sneffels range, but higher up some of the peaks have received wilderness protection.

The Mt. Sneffels wilderness contains Mt. Sneffels (14,150 ft.) and the surrounding mountains to the west. At 16,566 acres, the Sneffels wilderness ranks as one of the smallest wilderness areas of Colorado.

The Sneffels range is a subrange of the San Juan mountains, located on its northwest perimeter. The Sneffels are composed of igneous volcanic rock that form forbidding steep sided cliffs and pinnacles the give rise to jagged peaks and ridges. Much, if not all of the wilderness is high altitude, rugged terrain surrounded by steep subalpine forested slopes at the lower elevations.

Classic Colorado Landscapes

The view of Mt. Sneffels from Ridgway and the Dallas Divide region is considered one of Colorado’s classic landscapes. Each fall, photographers attempt to capture the brilliant autumn aspen foliage with the San Juan mountains as a backdrop. To visit the area, drive highway 550 south of Montrose to the small town of Ridgway. In Ridgway, take hwy 62 west (towards Telluride). The Sneffel range will appear to the south all along the route.


When to Visit

The Sneffels Wilderness trails are usually snow free by mid-July. Heavy, afternoon rains are common in the months of July and August.
