A favorite site for children of all ages. A visit to the Petrified Forest National Park will intrigue and excite everyone. Learn about the Ice Ages, prehistoric dinosaurs, and cave men that once inhabited this area. Discover how wood is turned to stone. The Petrified Forest National Park has one of the largest collections of stone logs in the world. Trees that died and sunk in the mud of ancient rivers about 225 million years ago. Absorbing the dissolved silica (sand) in the water that eventually crystallized into quartz to form the stone logs we see today.


The fossils found amidst the petrified wood help reconstruct life in a Mesozoic forest of ferns and cycads. When slithering crocodile-like reptiles and dinosaurs the size of small office buildings roamed the swamps.

Near the visitor center at the north end of the park is the Painted Desert. Named for its hues of red, orange, and pink sand that rise from the ground. Colors formed from iron oxides that concentrate in the sediment.

There are no campgrounds in the park and camping is limited to the backcountry which is free with a permit obtained at the visitor center.
