Reviewed By: Everettc3 Date Reviewed: 10/24/2010 Review Type: Trail Barefoot Friendliness: 2 Above Average Location: 25 Miles NW of Flagstaff Highway 180 Milepost 247 Flagstaff, AZ See map: Google Maps Picture: The trailhead for Red Mountain is 25 miles North East of Flagstaff off of Highway 180. You turn left at milepost 247 and drive about .5 miles to a parking area. The trail is 1.5 miles long and leads to the base of a 1,000 foot volcanic cinder cone. The first mile is on dirt and cinder pebbles which can irritate some pressure points but feels nice if those are trained. The last .5 miles is in a cindery wash that is almost like sand. Overall very nice on the feet, the scenery is beautiful, and the cinder cone is tons of fun to explore. Walking up the ridges and cracks of the cone itself is a bit rough but bare feet provide great traction for the steep slopes.
