2) Grand Canyon National Park

We cannot exclude the Grand Canyon National Park from this list. The Grand Canyons are located in Arizona and are considered to be one of the seven wonders of the world.
It is considered to be the second-most visited park in the U.S. You can zipline, raft the rapids of the Colorado River, or just enjoy the view from the Skywalk observation deck.
