Fodor's Expert Review Horseshoe Canyon Trail

This remote region of the park is accessible by dirt road, and only in good weather. Park at the lip of the canyon and hike 7 miles round-trip to the Great Gallery, considered by some to be the most significant rock-art panel in North America. Ghostly life-size figures in the Barrier Canyon style populate the amazing panel. The hike is moderately strenuous, with a 700-foot descent. Allow at least six hours for the trip and take a gallon of water per person. There's no camping allowed in the canyon, although you can camp on top near the parking lot. Difficult.

Call Hans Flat Ranger Station before heading out because rain can make the access road a muddy mess. Also, make sure to use a map as GPS can be unreliable here.
