As creepy as they might be, ghost towns are truly fascinating things. In fact, they're so fascinating that even the oldest, most worn-down ghost towns host hundreds (if not thousands) of visitors each year.

Many ghost towns are nothing but a pile of ruins at this point, but a few are still relatively intact. These deserted settlements are the best ones to visit, and if there are still people around to tell the stories of such places, it makes the trip even better. Luckily, it's not too hard to find these ideal ghost towns; some can even be found right here in Arizona.
