Hope Pass - 9.0 Miles Round-Trip

Hope Pass (12,508') is located 4.5 miles from Willis Gulch Trailhead in the San Isabel National Forest. This short but steep route begins off Highway 82 and joins the Continental Divide Trail up Little Willis Gulch to a saddle between Quail Mountain (13,461') and Mount Hope (13,933').

Trail Map | Photo Gallery

Views extend from Twin Lakes into the Collegiate Peaks, and both Quail Mountain and Mount Hope are challenging but fairly straight-forward walk-ups (Hope is decidedly more difficult).

The CDT continues south from Hope Pass down Sheep Gulch to County Road #390. Visitors will enjoy diverse forests, cascading creeks and big alpine landscapes on the way to Hope Pass:

From the parking lot, cross the bridge over Lake Creek and head straight on a path through tall brush. Ignore social trails that branch off along the creek.

Follow signs for Big and Little Willis Gulch #1471 that lead over beaver ponds to the Upper Twin Lake split (.37 miles : 9,435'). Here grades steepen through young aspen on a long SE arc into the gulch (1.0 miles : 9,835').

Travel moderates to a bridge (1.35 miles : 9,893') where it joins the CDT and steepens considerably in a tall, mixed forest beside the creek. There are many cascades on this stretch, though you'll have to work to see the most kinetic ones.

The trail climbs 385' from the bridge to the Little Willis - Big Willis Gulch Trail split (1.8 miles : 10,278'); bear left up Little Willis and resume steep climbing that gradually eases in a wide, flat piece of forest above the gulch (2.5 - 3.0 miles : 10,910' - 11,200').

It steepens back in a high, patchy forest before emerging through treeline in a postcard-like basin in the upper valley (3.65 miles : 11,722').

Travel moderates across alpine meadows with a great look at Mount Hope and a scenic tarn across the valley. The trail takes a winding but efficient route up the west flank of Quail Mountain to Hope Pass (4.5 miles : 12,508').
