At one point, giant reptiles roamed a towering forest of tropical conifers here. And while the dinosaurs are long gone, the trees are still here as shards of petrified wood littering the desert. Wandering through the trailless backcountry of Petrified Forest National Park, I feel like I’m the first human to ever set foot here. But I won’t be the last.

Plateau (mile 6)
Get the full Painted Desert experience when you overnight on this mesa. There are no established backcountry campsites in this park, so find a flat spot and savor 360-degree views, which include Chinde Mesa to the north and Pilot Rock to the west. Make sure to guy out your tent.
Be sure to check out Onyx Bridge, a 30-foot-long petrified tree, around 35.108566, -109.792206. If you follow the writer’s exact route, you’ll pass it between Lithodendron Wash and the campsite (near mile 2.1).
After your overnight, tack on an easy (just .3 mile) loop on the Puerco Pueblo Trail to see the largest-known archaeological site within the park.
Visit the expansion
