James Peak Wilderness

The James Peak Wilderness was designated as wilderness in 2002 by an act of Congress and signed by George W. Bush. The wilderness encompasses 17,084 acres with 15 lakes, 4 trails covering 20 miles, and crosses the Continental Divide at Rogers Pass. The elevation ranges from 9,200 to 13,294 feet, which includes upper montane, sub-alpine, and alpine ecosystems.


The James Peak Wilderness was named for its second highest peak, 13,294 foot "James Peak," in honor of Dr. Edwin James, an early explorer, historian, and botanist who was a member of the famous Stephen H. Long expedition to Colorado in 1820. The James Peak Wilderness is located just south of the Indian Peaks Wilderness and west of the town of Rollinsville. 


Planning your visit

The James Peak Wilderness is located a 1-hour drive southwest from Boulder and 1-hour 30 minute drive northwest from Denver. ​


The trailheads are located in the Arapaho and Roosevelt National Forests near the mountain towns of Nederland and Rollinsville.

Hiking Trails


The Indian Peaks Wilderness has 4 trails covering 20 miles. The East Portal trailhead begins at the Moffat Tunnel parking lot at the end of the East Portal Rd/Tolland Rd (a dirt road passable for most vehicles).


The very rough 4WD Rollins Pass Rd turns off the main road and provides access to Yankee Doodle Lake, Jenny Lake, the Needle Eye Tunnel and the Forest Lakes Trailhead. 

The East Portal Trail branches off to the Forest Lakes Trail, Crater Lakes Trail and Heart Lake/Rogers Pass Trails



The East Portal Trailhead has a large parking lot near the Moffat Tunnel - a restricted area where the railroad and water tunnels through the Continental Divide. The Moffat Tunnel is actively used by freight and passenger trains, including the Winter Park Ski train!
