Saguaro National Park is a United States national park in Pima County, southeastern Arizona. The 92,000-acre (37,000 ha) park consists of two separate areas—the Tucson Mountain District (TMD), about 10 miles (16 km) west of Tucson, and the Rincon Mountain District (RMD), about 10 miles (16 km) east of the city. Both districts preserve Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus.
