An all day auto tour is offered in Picket Wire Canyon on Saturdays during May, June, September and October. If you have a four-wheel drive, high clearance vehicle, this diverse trip should not be missed. You'll see rock art, wonderful scenery, an arch, ruins of a historic mission, a historic ranch and some well preserved dinosaur tracks.
