The 2,000-foot deep Oak Creek Canyon stretches for over 12-miles along a fault line. This drop in elevation is fully explored on this scenic drive which travels through the lush forests of Flagstaff and explores the glorious red-rock deserts, unique rock formations and rainbow-colored sandstone-cliffs on the way to Sedona.
