Arizona is best known across the United States for two things: Cowboys and Nature.

While the U.S. Government can do nothing to protect Cowboy culture, they can protect the natural world, and that's exactly what they did with the U.S. Parks System. This allowed for federal funding to protect certain areas of interest.

From volcanos and towering rock formations to cactus fields and ancient forests, Arizona has some of the most unique and beautiful National Parks in the country.
