Just north of Flagstaff, Arizona, you'll find a vast array of national monuments, forests and parks. One of the most unique parks within the region is Sunset Crater Volcano - its unique and violent history has resulted in incredible formations that will leave you hungry for more information and knowledge about the area.
If you're heading here in the summer, you'll have a few options for primitive campsites in the area. Summer in the park boasts opportunities for hiking, ranger-led discovery hikes, and the chance to see the area's famous night sky become splattered with millions of stars. In the winter, it might be best as a day trip, as many of the campgrounds in the area close once cold weather comes.
The landscape in this area is so unique that NASA sent the astronauts of the Apollo 16 and 17 expeditions to the Bonito Lava Flow to train, test out field equipment, and gain knowledge and appreciation for the stunning geological landscapes.
