East Snowmass Trail - 14.1 Miles Round-Trip
East Snowmass Trail runs 7.05 miles south from the backside of Snowmass Ski Area to a 12,684' pass separating the East Snowmass Creek drainage and Willow Lake basin. It continues approximately 1 mile and 680' down to the Willow Lake Trail, which rolls .7 miles across open alpine meadows to the lake (11,795').
The East Snowmass Trail is a lightly used route into the heart of the Maroon Bells - Snowmass Wilderness, an ideal choice for strong hikers looking to avoid crowds that emanate from Maroon Lake (there's also no fee).
The trail is distinguished by nearly 5 miles of open valley travel framed by colorful red walls leading up to the pass. It can be linked with the Willow Lake and Maroon-Snowmass trails to form a loop that scales Willow Pass and Buckskin Pass before dropping to Snowmass Lake and the Maroon-Snowmass Trailhead, just a few steps up the road from where you started.
Whether tackling it as a day hike or part of a longer backpacking route, get an early start to avoid summer storms on this exposed and challenging trail:
The East Snowmass Trail climbs steeply through aspen and mixed pine to the Wilderness Boundary (.65 miles) and Ditch Trail split (1.12 miles : 9,105'). It keeps a similar pace through diverse forests before emerging in open space (2.2 miles : 9,755') and moderating across rolling meadows in the lower valley.
It rises steadily with several short, steep intervals across open slopes to consecutive stream crossings at 3.45 miles (10,555'), the second of which is veiled by heavy brush.
Once through it enters a tall spruce-fir forest and eases for half a mile before another steep push leads to flat, stream cut meadows on the valley floor (4.3 miles : 11,040').
This is arguably the finest stretch to camp on the East Snowmass Trail no matter your final destination. The trail steepens past the meadows through the last bands of timber to treeline (5.1 miles : 11,455'). Travel now moderates across an expansive alpine landscape that rises incrementally to the pass.
At 6.0 miles (12,015') it bends SE and dips past an unmarked fork (keep left) and crosses a stream to the east side of the valley (6.35 miles : 12,065'). Once over it rises steeply up the east valley wall to East Snowmass Pass (7.05 miles : 12,684').
The pass spans a small notch on the valley headwall with exceptional views across the Willow Lake basin and a line of peaks across the Elk Range. It continues south on a very steep descent to the Willow Lake Trail split, which is .7 miles from the lake and .8 miles from Willow Pass (12,572').

Directions to Trailhead
The East Snowmass Trailhead is located on Divide Road on the (west) backside of Snowmass Village.
From Highway 82, turn onto Brush Creek Road and follow it 5.4 miles to Divide Road. Bear right on Divide Road and continue past Krabloonik Restaurant and Kennels, where it will turn steeply down toward the valley floor and turn to dirt/gravel.
Keep left at the fork and look for the trailhead on the left just over the wood bridge. The trailhead is 1.5 miles from the point where the road turns to dirt. High clearance is preferable but may be attempted by 2WD cars when the road is clear.
