You don't even have to be an American to know what the best thing about Arizona is. It's the Grand Canyon, which attracts millions of tourists to the state every single year. The whole state is beautiful, but that mile-deep geological wonder is truly special.
The only issue you'll find when you're visiting the Grand Canyon - or the state in general - is that it's almost too hot to think. Phoenix is the hottest city in the country, and on a summer's day, the temperature rockets up to 100 degrees.
