lies right at the south edge of Arizona, 20 miles from Nogales and the international border, and is easily accessed from Interstate 19, though not too many people come here. The preserve contains three settlements dating from the Spanish missionary period of the mid 1700s; little remains of two, but the main site, Mission San José de Tumacácori
, contains a varied array of well preserved buildings, centered on a handsome brick church. The mission has quiet, tree-lined, residential surroundings, and is a peaceful, evocative place to visit.
