Three Mile Creek

The Three Mile Creek Trailhead (#635)(on some maps Threemile Creek) starts at an elevation of 8,725' and climbs steadily up Three Mile Creek to an elevation of 11,625'. Cross the creek more than a dozen times and travel through aspen groves along with conifer forest. This is a beautiful serene fall hike. There is a huge beaver dam at 1.65 miles up from the road. The Three Mile Creek watershed eventually ends at Rosalie Trail (USFS #603) which in turn provides access to multiple trails in the Blue Sky Wilderness, including Tanglewood (USFS #636) (Bailey), Bierstadt (USFS #711), and Abyss (USFS #602).

Parking and access are shared with the Whiteside Picnic Area and Campground, the first parking area on Geneva Pass Rd out of Grant on your left. It is 2.4 miles from US-285.  Follow the trail about .5 mile north until you cross Geneva Pass Rd. to enter Three Mile Creek Trail proper. There is no parking at the road crossing.

Whiteside Campground has 5 campsites for tent camping only. It is located at 8,900 feet and is open year round on a first-come, first-served basis. There is no water available at this site, but they do offer vault toilets and picnic tables.
