This past week, Blake Smith, Robert Croke, Harvey Smith, Ron Ziance and I decided to hike the Calico Hills are a 3.2 mile long section of brilliantly red sandstone cliffs, easily what is one of the Red Rock Canyon's most beautiful features. Below the road, at the base of the hills, there are numerous trails that traverse open country with interesting rocks, fossils, birds, rock art, contrasting vegetation types, and grand scenery all around. The main trail is known as The Calico Hills Trail. runs one-way from the Entrance Station to Sandstone Quarry. Click here for pictures and description … Calico Hill Trail Hike - (RRCNCA).
