From alpine forests to saguaro-framed sunsets, the landscape is inescapable in Arizona. While the state's natural landmarks are the easiest to see, thousands of years of human habitation have also made their mark on the terrain: Many of the canals that irrigate Phoenix follow the contours of the ditches that the ancient Hohokam dug a thousand years ago. The unwaveringly sunny weather makes an outdoor lifestyle possible year-round, and a growing food scene means you'll never go hungry. From archaeology to gastronomy, Arizona offers up endless layers to discover. The Grand Canyon is just the beginning.
