Tucson Mexico Sister Cities
Image
Tucson Mexico Sister Cities was established in 1972. That same year we welcomed our first sister city partner, Guadalajara, Jalisco. In 1980, Ciudad Obregón, Sonora became Tucson’s second sister city. Subsequently, we were honored to add Mazatlán, Sinaloa to our distinguished list of sister cities relationship. And most recently we welcomed Puerto Peñasco, Sonora.
