Saguaro National Park protects one of the most iconic desert landscapes in the United States. Located near Tucson in southern Arizona, the park is famous for its towering saguaro cacti, some of which can grow over 40 feet tall and live more than 150 years. The park is divided into two districts—Tucson Mountain District (west) and Rincon Mountain District (east)—both offering scenic desert hikes, mountain views, and incredible sunsets across the Sonoran Desert.
