Petrified Forest is the only national park that I-40 runs directly through. Most drivers pass without stopping. That is a mistake. This park holds the largest concentration of petrified wood in the world: entire logs turned to stone 225 million years ago, scattered across a painted desert landscape. The park road runs 28 miles between two entrances, with overlooks and short trails throughout. One hour is enough to see the colorful badlands, touch petrified wood, and appreciate what deep time looks like.
The Essential Stop
Crystal Forest Trail
A 0.75-mile paved loop through one of the densest concentrations of petrified logs in the park. Massive sections of crystallized trees lie scattered on the desert floor, some over six feet in diameter. The colors in the wood, from deep reds to purples, come from different minerals absorbed during fossilization.
Do not take any petrified wood. It is a federal crime. The park loses a ton of material annually to theft.
One Hour Experience
Enter from I-40 Exit 311 (north entrance) and drive south. This route hits the highlights efficiently.
Painted Desert Visitor Center
Quick orientation and restrooms. The Route 66 display is worth a glance. Skip the film if short on time.
Painted Desert Overlooks
Several overlooks in the first few miles. Stop at Tiponi or Tawa Point for the red, purple, and gray badlands stretching to the horizon.
Crystal Forest Trail
The essential stop. Paved loop through massive petrified logs. This is what you came to see.
Giant Logs Trail
Near the south entrance. A short loop with the largest logs in the park, including Old Faithful, a log nearly ten feet in diameter.
If You Have More Time
Blue Mesa Trail
A one-mile loop descending into blue and white striped badlands. The most striking landscape in the park.
Agate House
A partially reconstructed pueblo built from petrified wood. Two-mile round trip hike.
Newspaper Rock
Petroglyphs carved by ancient peoples. View from an overlook with spotting scopes.

Tips
- The park road connects two I-40 exits. Enter at one, exit at the other. No backtracking required.
- Do not take petrified wood. Every piece in every pocket adds up to tons of loss per year. It is illegal and enforced.
- The painted desert section is in the north; the petrified forests are in the south. Both are worth seeing.
- Holbrook, 25 miles east, has the famous Wigwam Motel if you want to sleep in a concrete teepee.
- Afternoon thunderstorms in summer can close roads. Check conditions if visiting July through September.
