Devil's Hall Trail
Wind through a Chihuahuan Desert habitat thick with spiked agave plants, prickly pear cacti, ponderosa pines, and a dry riverbed strewn with giant boulders to Devil's Hall, a narrow 10-foot-wide canyon with walls that soar to more than 100 feet. At a leisurely pace, this 4.2-mile round-trip jaunt will take three or four hours. Moderate.
