Directions: The Four Mile Creek Trailhead is located on Lee Hill Rd. Coming from Boulder/Denver take either Hwy 36 or Highway 93 north, turn west on Lee Hill Road and the trailhead is a few blocks west on the left.

From the parking lot you start on the Foothills Trail, cross a creek, and make a right at the trail junction with the Old Kiln Trail. This area was hit heavily by last years massive flooding. The trail was washed out and has been rebuilt along the creek. Follow cairns when the trail gets difficult to spot. After following the creek for a little, the trail starts switchbacking and ascending onto the north slope of the hill. Follow this slope till you reach a nice view of the Lee Hill Road Canyon area and a gate marking the end of City of Boulder OSMP property. From here turn around but this time make a right and complete the lower loop. There are nice views here looking north to Green Mountain. Overall a very pleasant, short hike, with decent elevation gain, for the distance.
