Threemile Trail #635
This trail provides access into the southern portion of the Mount Evans Wilderness, offering spectacular high mountain scenery and vistas.
The first part of the trail follows the west bank of Geneva Creek north from the trailhead, then crosses Geneva Creek and the Guanella Pass Road. It continues north at a distance uphill from the road to Threemile Creek, then continues northeasterly following the creek. The trail is in a narrow valley with many stream crossings. As the route swings more toward the east, the valley gradually begins to open up into a meadow. From a point east of Spearhead Mountain, the trail begins to rise steeply away from the creek in a series of switchbacks. At the top of the switchbacks, the trail begins heading north. Shortly, you emerge from the trees into open tundra. Kataka Mountain will be on your left (west), and Mount Evans and Mount Bierstadt will be ahead of you and slightly to the left. Continuing north, the trail descends to meet the Rosalie Trail #603.
General Information
Year-round
There is a mandatory self-issued permit system in the Mount Evans and Lost Creek Wilderness areas to enable us to better manage visitation. The same type of system is also in place in other wildernesses. The intent is to use the data obtained through the permit system to more accurately assess the amounts and types of existing wilderness use. This enables us to better preserve their natural condition for future generations, balanced against the pressures of growing populations and increased use. These permits have no quotas associated with them, nor are there any fees required to obtain them. They are available free at each trailhead. As you enter the wilderness, fill out the provided permit and deposit the stub in the slot in the lower front of the register box. Keep the permit in your possession and please follow the wilderness regulations found on the back.

Getting There
Directions
Drive southwest from Denver on U.S. Highway 285 approximately 40 miles to Grant. Turn right (north) onto Park County Route 62 (Guanella Pass), and drive 2.5 miles to the Threemile Trailhead/Whiteside Picnic Area on the left (west) side of the road.
With the improvement of the Guanella Pass road, the trailhead was moved ½ mile south of the old trailhead.
