Hiking in the Flat Tops Wilderness
4 trails in this Colorado region — with elevation, distance, and seasonal recommendations.
Devils Causeway Trail
Famous ridge traverse in the Flat Tops Wilderness. The Causeway is a 4-foot-wide rocky knife-edge ridge with dramatic exposure on both sides. From the Stillwater Reservoir Trailhead, climb to the ridge and traverse the narrow section. Vertigo-inducing for some.
East Marvine Trail
From the Marvine Trailhead, follow East Marvine Trail through aspen and conifer forest into the Flat Tops Wilderness. Excellent fall colors in mid-September. Quiet backcountry experience with backpack camps along the trail.
Stillwater Reservoir Loop
Easy lake-side walk around part of Stillwater Reservoir at the southern Flat Tops trailhead. The trailhead is the start for the Devils Causeway and other Flat Tops destinations. Family-friendly while bigger trips happen above.
Service Creek Trail
Lower-elevation Flat Tops trail through aspen forest along Service Creek. Excellent shoulder-season option when high country is still snowy. Wildlife viewing for deer and the occasional moose.
