Route Information and Additional Resources
This trail is located almost entirely within the Mt. Evans Wilderness Area, and you’ll need to fill out a free Required Registration permit at the trailhead. From the Guanella Pass Trailhead at 11,650 feet, descend southeast and follow the boardwalk through the willows. At 11,470 feet, the trail crosses Scott Gomer Creek and begins its ascent toward the summit. The trail then climbs up onto the broad northwest shoulder. Nearing the summit, the trail grows steeper and less well defined on the rocky ridge. Stay on the rocks and avoid the vegetation growing in the pockets in between.
For more information about Mt. Bierstadt or regulations within the Mt. Evans Wilderness, please visit the U.S. Forest Service website.
The above information does not replace the need to consult additional maps and Colorado Fourteener guidebooks for more detailed route descriptions. We suggest checking multiple resources before departing on any hike. Keep in mind that not all guidebooks list this recommended route and that each guidebook’s description or route name may vary slightly.
Peak Specific Environmental and Safety Concerns
Because this trail is entirely above treeline, you should be alert to the likely development of summer afternoon storms and lightning. The area around the around Guanella Pass is prime White-tailed Ptarmigan habitat and loose dogs cause disturbance in this and other communities. Stay on the trail to avoid trampling alpine tundra, and do not cut switchbacks.
