What: When most travelers think of Northern Arizona, they envision the deep reds of Sedona or the vast depths of the Grand Canyon. These are world-class destinations, but if you drive past Flagstaff without stopping, you are missing some of the most unique volcanic landscapes in the United States. Sunset Crater Volcano is an "island" of high-altitude geology that feels like a different planet, offering a "boost" of wild nature that is easily accessible even for a short visit. This park protects one of the youngest volcanoes in the San Francisco Volcanic Field, an area that was transformed by a powerful eruption around 1100 AD. Standing before the orange and brown cinder cone, you can see exactly where the molten earth once flowed, creating a stark contrast between jagged black lava fields and the lush green of the surrounding pine forests.
