Tucson has plenty to offer outdoor enthusiasts, history buffs, urban cowboys, and culture vultures alike. Spread out over a 500-square-mile valley
surrounded by five mountain ranges, Tucson is a fresh-air fan's dream.
Tucson is also nicknamed as "Astronomy Capital of the World." Anyway, Tucson is a definite jumping-off point for many other terrific Southern Arizona day trips.
