Sunset Crater and Wupatki National Monument Professional Review and Guide
"Sunset Crater National Monument is a 1,000-foot-high historic cone. Here you will find strange rivers of lava that erupted 900 years ago that look as though they happened yesterday. There are many trails to hike along and explore; visitors, however, are asked to stay on the trails and not forge their own. The lava flow is brittle and can be damaged easily.
There is a park service station and interpretive center that explains the history and geology of the area. Self-guided trails make it easy to stroll among these structures and understand the significance of the sites. This chapter from the DayTrips series describes many fascinating, exciting, (and many free of charge) things to do, most within a two-hour drive of Flagstaff. Each Day Trip includes destination highlights, places to visit along the way, choice restaurants and lodging, and shopping."
