Although Tucson's fantastic weather, national parks and forests and desert provide the perfect environment for tons of outdoor recreational activities, this city of half a million people also has its share of history and culture. With a history that goes back much further than many of its southwestern neighbors, Tucson boasts turn-of-the-century architecture, historic neighborhoods, museums and the Mission San Xavier del Bac, a still-functioning 18th-century mission considered one of the most beautiful in the U.S. Mexican and Native American influences are pervasive, and the city has a distinctly Western flavor. There's also a college-town atmosphere, thanks to the University of Arizona, which has its own share of museums and a science center. Whether golfing at a world-class golf resort, horseback riding, hiking in the wilderness, discovering desert flora and fauna at the Arizona-Sonora Desert Museum or exploring pre-Columbian and other art at the Tucson Art Museum, you'll have a mind-boggling array of things to do.  More info
