Turn right toward Indian Creek and Cottonwood Canyon. After about a mile, there is another intersection with a sign. Turn left toward Indian Creek. Drive 2 miles to the Indian Creek Campground and turn right onto the Spoon Creek Road. Drive about two miles until you reach a fence and cattle guard.
East Mountain is the peak on the north side of the fence.
Notice the treeless area near the top. There is no trail. Head toward it by first following the fence up the drainage, then climbing the steep open area to the peak. Expect to hike over some deadfall in a thick forest. A geologic survey marker is found near the top of the peak.
