Petrified Forest National Park

Petrified Forest National Park


Managed by National Park Service

Established 1906 National Monument, 1962 National Park

221,390 acres



East of Flagstaff, Arizona on Interstate 40 (the historic Route 66) is Petrified Forest National Park, which started as one of the first National Monuments created by President Teddy Roosevelt.  It is hard to believe in the dry expanses of the Painted Desert, but 225-million years ago this land existed in a tropical climate where trees grew to 200 feet in height.  Some of those trees were buried in mud when they fell and over time silica crystalized in their decaying cells forming colorful rocks.  You can still see annual growth rings and rays from the wood preserved on the cross-sections that look like they were cut by a chainsaw.  The rocks are protected inside the park, so for a souvenir head to the gift shops around the park’s borders.

Must-Do Activity

It is the kaleidoscope of colors that makes this park so beautiful and unique.  The intricate weave of minerals in each bit of petrified wood is found in an array of colors: red, orange, yellow, green, purple, black, and white.  A paved walkway behind the Rainbow Forest Museum is a great place to start, as rangers give guided tours there throughout the day.  In the warm season, watch for the bright colors of a collared lizard hiding among the rocks.  It is worth a hike to Agate House and a connection to the Giant Logs Trail to see more petrified wood, but be sure to bring water with you in the summer since there is no shade.

Best Trail

Blue Mesa Trail is only one mile in length, but you will stop so often for photos that it seems much longer.  In this area the blueish bentonite badlands are striped by reduced iron and rust (as depicted in our logo illustration).  The trail can be muddy if there has been recent precipitation.

Instagram-worthy Photo

The Painted Desert often lives up to its name during the golden hours of sunrise and sunset when the pink adobe walls of the Painted Desert Inn can positively blaze.  After summer thunderstorms, watch for rainbows that hang under the billowy cumulus clouds.

Peak Season

Spring and fall



$25 per vehicle or America the Beautiful pass

Road Conditions

All roads in the park are paved and the 28-mile paved scenic drive is nice in either direction.


There are no overnight facilities within the park, but there are private campgrounds in both Holbrook and Winslow, Arizona.  Lyman Lake State Park also offers camping.  A free backcountry permit is required to camp in the Wilderness area north of the Painted Desert Inn.  There are no trails and the only requirement is that you cross Lithodendron Wash about a mile from the rim, which sometimes means walking through shallow water.
