Petrified Forest Loop Details

It's a little-known fact that Theodore Roosevelt National Park has the third-largest collection of petrified wood in the United States. The ancient Petrified Forest is located in the northwest corner of the South Unit, in a remote, untouched area of the wilderness. The 10-mile Petrified Forest Loop may be accessed by foot or horseback from a private road on its west side, or from the east near Peaceful Valley Ranch. There are two main concentrations of petrified wood: along the North Petrified Forest Trail and along the South Petrified Forest Trail. This area is remote, with no services, so bring adequate water, food, apparel, and sun coverage. It is prohibited to disturb or remove petrified wood or other rocks in the park.
