West Maroon Pass

Distance: 3.4 - 13.0 miles (round trip)

Maroon Bells-Snowmass Wilderness, White River National Forest, near Aspen in Central Colorado

Introduction

View of the Pyramid massif

Wonderful views of the Maroon Bells and Pyramid Peak, pretty waterfalls, two stunning lakes and a scenic alpine basin await hikers on this popular 13-mile (RT) hike to West Maroon Pass. The journey follows the Maroon-Snowmass trail to Crater Lake the climbs the long, narrow West Maroon valley beneath the towering crags of the Maroon Bells and Pyramid massifs.

The pass is located on a ridge at the head of the valley above a huge basin rimmed with maroon cliffs and clad in emerald meadows sprinkled with wildflower. Views from the pass extend west to Treasure Mountain. To the east the Maroon Bells and the Pyramid Peaks fill the skyline.

The popular hike is part of the famous 26-mile Four Pass Loop, a backpacking trip climbing four pass over 12,000-ft. in the Maroon-Snowmass Wilderness. With proper planning the route is part of a longer day hike to Crested Butte or a the first segment of a two day trip covering the West and East Maroon trails with overnight accommodations in Crested Butte.

Trailhead to Crater Lake

Crater Lake and the Maroon Bells

Distance from Trailhead: 3.4 miles (round trip)

Ending/Highest Elevation: 10,076-ft.

Elevation Gain: 496-ft.

Few trails can surpass the stunning views from the start of the West Maroon Pass hike at the foot of Maroon Lake. Mirrored in the lake’s waters are the iconic Maroon Bells (14,156-ft. and 14,014-ft.), towering above the head of the valley. Pyramid Peak’s (14,018-ft.) jagged crags rise to the south while the crimson spires of the Sievers Mountains form the backdrop for beautiful aspen groves to the north.

Follow the Maroon-Snowmass trail along Maroon Lake’s north (right) shore to a junction at the "Deadly Bell's Kiosk" near the head of the lake. Progress will be slow along this section of the trail as the gorgeous scenery invites frequent stops.

At the junction the Scenic Loop Trail branches left. We turn right to stay on the Maroon-Snowmass trail, which ascends a wide rocky path through Aspen and spruce trees along the northwest side of the valley. Openings in the trees offer views of rugged Pyramid Peak rising to the south.

About a mile from the start the moderately steep trail climbs an ancient rock slide forming a natural dam that created Crater Lake. As you reach the top of the slide enjoy wonderful views of the Maroon Bells and the Sleeping Sexton, located on the ridge extending north from North Maroon Peak.

From the top of the slide the trail descends gently toward Crater Lake. Slightly before reaching Crater Lake arrive at a junction at 1.7 miles. Continue straight ahead (south) on the West Maroon trail toward Crater Lake and West Maroon Pass. The Maroon-Snowmass trail to the right (west) leads to Buckskin Pass.

After descending to the foot of Crater Lake the trail traverses the lake’s right (western) shoreline. Along the way enjoy wonderful views of the Maroon Bells. (Backpackers will find designated campsites among the trees on the western side of the lake.)

At the head of the lake vistas open up the valley. Watch for waterfalls cascading down the western valley wall along this section of the trail.

The trail now follows a gentle grade through meadows, willow thickets and trees and then climbs steeply over a rockslide spilling from the eastern flanks of Maroon Peak. Be sure to turn around at the top of the slide and enjoy great views down valley.

Beyond the slide the trail negotiates a narrow corridor between the creek and talus fields, passing through willows tickets and conifer stands. As the corridor constricts, the trail crosses a few talus fields before being forced to cross to the east side of the creek at 3.6 miles. Early in the season you will need to wade the creek. As the snow runoff subsides, you should be able to rock hop across the braided channel without getting your feet wet.

On the east side of the creek the ascent steepens as the path bashes its way through a large thicket of willows and then continues climbing through a landscape of scrub growth interspersed with conifer stands, some of which harbor nice campsites. Depending on the time of year you might see waterfalls spilling down the eastern wall of the valley along this segment of the trail.

At 4.5-miles the trail crosses back to the western side of the creek and continues its ascent. Soon the last of the trees give way to thickets of scrub willows and the grade steepens as you approach the head of the valley, a large basin rimmed with maroon cliffs and clad in emerald green meadows sprinkled with wildflowers. Be sure to turn around as you climb and take in the wonderful views of the Pyramid massif towering above the eastern side of the valley.

The trail through the basin’s meadows veers right (west) as it negotiates the rolling landscape. Near the head of the basin the path crests a rise and heads southwest toward a low point on the ridge. As you near the ridge the way to the pass becomes apparent. The final slog through meadows and stiff ascent of the pass gains 800-ft. in 0.7 miles.

From the top of the pass views extend west to Treasure Mountain. Below are the vast meadows of Purity Basin. To the northeast the Maroon Bells and Pyramid massifs fill the skyline. Belleview Mountain rises along the rugged ridge extending northwest from the pass.

The pass is the turnaround point for most day hikers. Backpackers use the trail as either the first or last leg of the popular 26-mile Four Pass Loop, a 3-5 day backpacking trip climbing four passes over 12,000-ft. in the Maroon-Snowmass Wilderness.

Note to Backpackers: Beyond the designated camping sites a Crater Lake, camping came be found in the conifer stands along the east and west side of the West Maroon Valley. If you are doing the Four Pass Loop it is best to camp before West Maroon Pass or after Frigid Air Pass. Camping is very difficult in the Purity Basin between the two passes.

With proper planning it is possible to cross West Maroon Pass on a day hike and end up at the East Fork trailhead in Schofield Park, 14 miles from Crested Butte. (For more information see the West Maroon Pass from Crested Butte trail description.) You need to spot a car at the Schofield Park trailhead, arrange a ride (taxi: (970) 349-2620 or (970) 948-9893) or try to hitch your way back to Crested Butte (not recommended on the infrequently traveled road).

Some folks make this into a two day trip by staying in Crested Butte overnight and then arranging transportation to the East Maroon trailhead for a 16-mile one-way hike back to the East Maroon Trailhead. You then need to either walk up valley to Maroon Lake or take the shuttle bus back to Aspen.
