Updated 11/25/2013

Fodor's Review

Although bits of petrified wood have been found all over the park, the densest collection is in the South Unit's west end, accessible on foot or horseback via the Petrified Forest Loop Trail from Peaceful Valley Ranch (10 mi round-trip) or from the park's west boundary (3 mi round-trip).

Sight Information


Trailheads: Peaceful Valley Ranch, 7 mi north of the South Unit Visitor Center; west boundary, 10 mi north of exit 23 off I–94/U.S. 10, Theodore Roosevelt National Park, North Dakota, 58645, United States
