Presidio Santa Cruz de Terrenate National Historic Site is 4 miles north of Tombstone on SR 80, 6 miles west on SR 82 to Fairbank, .75 miles west to In Balance Ranch Road, then 2 miles north in the San Pedro Riparian National Conservation Area. Established by the Spanish in 1776 on the banks of the San Pedro River, the presidio was built to protect the overland route east of Tucson. Because of the frequent Apache raids as well as the lack of proper supplies, Terrenate was abandoned less than 5 years after its establishment. Learn More...
