Young or old, newbie or seasoned Tucson resident, you have to check out the Arizona Sonora Desert Museum as your absolute first call. This isn’t just any museum – this is an art gallery, botanical garden, natural history museum, zoo, aquarium and more. This is a place to find out about the history of the Sonoran desert bioregion and its many ecosystems. Plus on Tucson’s most scorching days of the year, you can see javelinas sleeping soundly underneath the bridge (local pigs).
