Great trail, basically a walking tour of Red Rock. I've done it clockwise and counterclockwise and don't really have a a preference on which is the "better" way to travel the loop. Clockwise gets the "boring" Jeep trail out of the way and leaves the scenic Calico portion for the end. Counterclockwise gives you a great scenic start and ends with an easier return on the Jeep trail. Can't go wrong either way. Pretty easy to follow, can get a little hard to find the trail when it intersects with the trailheads but nothing too frustrating. Definitely recommend waiting for cooler weather to do this hike.
