Mount Sopris

Like a Mount Shasta of Colorado, Mount Sopris rises dramatically from the Roaring Fork Valley floor, creating a looming, venerable presence in the wilderness north of Aspen.

  • This formidable summit in the sky dominates the Carbondale, CO, vista.
  • Summit access at Thomas Lakes Trailhead. Use topo map and caution. (No horses or bikes.)
  • Fish to your heart's content at Dinkle and Thomas Lakes.
  • Bike along Hay Park Trail for epic views of the mountain.


At 12,965 feet, Mount Sopris does not hold the title of Colorado's highest peak, but it certainly presents itself as a formidable summit, dominating the vista views from Carbondale, CO. Mount Sopris, with an east and west summit, has become a rite of passage for mountaineers in the greater Aspen area. A forest ranger remarked that folks have moved to the area just to conquer Mount Sopris.


Located west of Snowmass Village and south of Carbondale, recreation in the vicinity of Mount Sopris can be accessed by heading south on Highway 133 (at junction of CO-82 at Carbondale) about 1.5 miles, then left on Prince Creek Road. Biking and hiking access points can be found along this road. For updated information regarding trail maintenance and weather conditions, contact White River National Forest at the Sopris Ranger District by calling (970) 963-2266.


The summer months of July and August propose your best bet for a safe summit of Mount Sopris. Hiking, biking and fishing can be enjoyed during the Spring, Summer and Fall. Any time of the year, however, be prepared for the worst of weather conditions, as a warm, sunny day in August can quickly become an afternoon of severe weather and freezing temperatures. Contact the ranger district for current information.


Mount Sopris, in the Elk Range, stands within the designated Maroon Bells-Snowmass Wilderness in White River National Forest. For maps of the area, visit Aspen or Sopris Ranger Districts offices.

Thomas Lakes Trail: For access to Mount Sopris summits (east and west), take Prince Creek Road for 6 miles until road forks. Bear right, and drive 2 miles to trailhead. White River National Forest recommends planning two days to summit, with camp set-up at Thomas Lakes, and a morning summit (about 4 miles from lakes). The easiest approach can be found via the east ridge. The hike boasts a total elevation gain of 4253 feet and demands solid endurance from hikers. Hikers will not find a designated summit trail, so proper maps and orientation, along with sound judgment regarding weather conditions, are necessary for a safe summit.

Designated sites can be found at Thomas Lakes. No dogs are allowed.
