Petrified Logs Loop: What to Know Before You Go
Petrified Logs Loop is a short, easy walk past four ancient trees that have literally turned to stone — likely around 150 million years old, each one individually fenced for protection, set in a shallow basin flanked by deep red Aztec sandstone. Interpretive panels along the route explain how groundwater slowly replaced the wood's cell structure with minerals over time. Welcome to Petrified Logs Loop, a quick, genuinely educational stop open year-round.

How to Reach the Trailhead
Turn onto a signed gravel access road ("Petrified Logs") off the south side of the main park road, about 4 miles west of the Historic Cabins, and follow it 0.2 miles to a small lot. Standard entrance fee applies.
What to Expect on the Trail
One of the easiest walks in the park — a short loop with a gentle descent from the trailhead, curving past the logs, then a short uphill return. The route sits in a shallow basin flanked by deep red Aztec sandstone, with four individually fenced petrified logs along the way.
150 Million Years in the Making
Sources mostly agree the logs are roughly 150 million years old, consistent with the park's dominant Jurassic-age Aztec Sandstone — one source instead attributes them to the older Triassic-era Chinle Formation, a meaningfully different and less-supported claim worth treating as a minority view. The petrification process is well-documented: groundwater carrying dissolved minerals infiltrated the wood's microscopic cell structure and gradually replaced the organic material, leaving behind the dull reddish-brown stone logs visible today.
Best Time to Visit and Conditions
Open year-round; the short distance makes it workable in any season.
Practical Advice for New Visitors
- Bring water for the short walk.
- Bring a camera for the petrified logs.
- Pack sun protection.
- Look for all four individually fenced logs, not just the first one you see.
- Read the interpretive panels on petrification with kids.
- Don't touch or remove any petrified wood fragments.
- A quick, easy add-on to a longer day in the park.
- Leash your dog for the walk.
For a quick, genuinely educational stop about deep geological time, Petrified Logs Loop is a worthwhile short addition to a Valley of Fire visit. Take a moment at each log, read the interpretive panels, and leave the ancient wood exactly as you found it.
