The Arizona-Sonora Desert Museum is a 98-acre (40 ha) zoo, aquarium, botanical garden, natural history museum, publisher, and art gallery. Located just west of Tucson, Arizona, it features two miles (3.2 km) of walking paths traversing 21 acres (8.5 ha) of the desert landscape. It is one of the most visited attractions in Southern Arizona.
The Desert Museum was founded in 1952. It interprets the complete natural history of a single region—the Sonoran Desert and adjacent ecosystems—with plants and animals from the region featured together in its exhibits.
The nonprofit organization focuses on the interpretation of the natural history, plants, and animals of the Sonoran Desert. The museum is home to more than 230 animal species and 1,200 varieties of plants. It is open every day through the year, and hosts nearly 400,000 visitors annually, including visitors from abroad.
The museum is an accredited member of the Association of Zoos and Aquariums, a member of the American Alliance of Museums, and the American Public Gardens Association.
