The Arizona-Sonora Desert Museum is more than 60 years old and is dedicated to making people understand what the desert is really all about. It does a pretty good job. This is not a museum like you know it, it is a mix of a botanical garden, a zoo, a natural history museum, an art gallery and an aquarium. Within that all, you will find about 2 miles of hiking trails. You can easily spend a couple of hours within the desert museum, there is so much to discover and see. The museum is a few miles west of Tucson, you can easily combine it with the Saguaro National Park.
