Horseshoe Canyon, an outlying unit of Canyonlands National Monument, is isolated, hard to get to and worth the effort! The canyon, once known as Barrier Canyon, contains probably the largest and most striking painted rock art in all of the Southwest. The figures are amazing, many of them are larger than human size and having intricate details and evidence of various colors. I had been wanting to get to this place for more than five years. It was worth it, even on a very hot day and several hours of hiking into the canyon and back out.(click here).
