Douglas, AZ

Douglas is a Cochise County city on the U.S.-Mexico border, directly across from Agua Prieta, Sonora. Its story is tied to mining, cross-border movement, and the Sulphur Springs Valley in southeastern Arizona. The historic Gadsden Hotel, opened in 1907, gives downtown one of its clearest landmarks, and several local sites are listed on the National Register of Historic Places. Douglas feels like a border city with a deep Arizona mining-era past.
