Crystal Forest Trail - 0.85 Miles Round-Trip
The Crystal Forest Trail loops through rolling grasslands and badland formations highlighted by a stunning collection of petrified wood.
The trail is easily accessed from Park Road, and friendly to families and persons of all abilities.
Photographers may prefer afternoon light on petrified wood remains, while sunrise illuminates the The Battleship, an isolated fin just off to the west (pictured above).
During the late Triassic Period some 225 million years ago, much of Northern Arizona was a heavily wooded tropical floodplain. Period flooding and erosion interspersed with volcanic activity from the south and west carried sediments and ash downstream, settling over fallen trees in this area.
In some cases trees were buried quickly and deeply enough to deprive them of oxygen, thus significantly slowing the natural decomposition process. Over time, ground water dissolved silica from volcanic ash into the porous body of fallen, buried trees.
This solution formed quartz crystals that filled hollows and cracks in the logs, eventually petrifying them by encasing and replacing the trees' organic material with minerals.
The wood's brilliant colors come from impurities in the quartz, such as iron, carbon, and manganese.

- Petrified wood in the Petrified Forest National Park is almost solid quartz, weighing on average between 150-180 pounds per cubic foot. It's so hard, you can only cut it with a diamond tipped saw.
- Petrified wood is mostly quartz. The physical characteristics of cylindrical quartz cause it to break cleanly when stressed, resulting in the symmetrical segments we see today.
- Iron Oxides give the wood its distinctive red, yellow and orange hues.
- Carbonized organic compounds and residues yield black, tan and brown tones.
- Shortgrass prairies and pockets of high desert cover a majority of the Park. The Park's ecology is technically classified as an Inter-mountain Basin, Semi-Desert Shrub Steppe and Grassland.
Rules and Regulations
- Collection of plants, rocks, petrified wood, fossils, archeological objects or other materials is illegal anywhere in the park. Rules are strictly enforced and violators are subject to significant penalties.
- Pets are permitted on maintained trails, but must be kept on a leash at all times. Pets are not allowed within Wilderness Areas, nor on the Wilderness Access Trail near The Painted Desert Inn. Pets are not allowed in buildings unless they are service animals.
Directions to Trailhead
