Devils head is a distinct granite rock outcropping in the front range west of Castle Rock. The outcropping is clearly visible from Castle Rock to Woodland Park. The Devil’s Head Lookout Trail begins in the picnic area adjacent to Devil’s Head Campground and ends at Devil’s Head Lookout, the last of the seven original Front Range Lookout towers still in service. The 1.4 mile long trail takes approximately 45 to 90 minutes on a one way hike, with an elevation gain of 940 feet. More information here.
