Tucson is home to one of the most iconic symbols of the West: the Giant Saguaro. This monolithic, sub-tropical plant can be seen along desert roads and clustered at the base of Tucson's hillsides and mountains. Get your fill of this beautiful and unique desert scenery with a visit to Saguaro National Park, which is bifurcated into two large swaths, situated on both the western and eastern edges of the city.
Another can't-miss is the Arizona-Sonora Desert Museum, located deep in the desert of Tucson's westside. This impressive "living" museum features extensive walking trails, gardens, and unique outdoor exhibits where you can get up close to mountain lions, coyotes, and maybe even spot a javelina or two.
While you're on the westside, clear some time in your itinerary for a stop at Old Tucson Studios. Movie buffs will recognize the film studio as the location for such films as Tombstone and The Three Amigos. There are western-style shoot-outs, a fun saloon cabaret show, and plenty of carnival-like games and attractions.
History buffs will want to stop in downtown Tucson to visit the Tucson Museum of Art and Historic Block. You can poke around the remains of the city's historic presidio fort, and tour some of the oldest houses in the state of Arizona.
