Petrified Forest National Park is unlike anywhere else in the world. Located in northeastern Arizona, this remarkable national park is home to one of the largest and most colorful concentrations of petrified wood on Earth. But there is much more to discover than ancient trees. Visitors can also explore vibrant badlands, fascinating archaeological sites, historic Route 66 landmarks, and landscapes that seem almost otherworldly. Whether you are planning a road trip across Arizona or simply looking for a unique outdoor adventure, Petrified Forest National Park is a destination that combines geology, history, and natural beauty into one unforgettable experience.

The park’s most famous attraction is its petrified wood, which began as living trees more than 200 million years ago during the Late Triassic Period. After the trees fell, they were buried by layers of sediment and volcanic ash. Over millions of years, groundwater rich in minerals slowly replaced the original wood tissue with quartz, preserving the tree’s structure while transforming it into stone.
The result is beautifully preserved logs that sparkle with vibrant colors, including reds, oranges, yellows, purples, and blues, created by different minerals.
The northern portion of the park includes the breathtaking Painted Desert, a landscape of rolling hills and layered rock formations that display brilliant shades of pink, lavender, gray, red, and orange.
The colorful bands were created over millions of years as different layers of sediment were deposited and exposed through erosion. Sunrise and sunset often provide the most spectacular views as the changing light brings out even more vibrant colors.
Petrified Forest National Park offers several easy-to-moderate hiking trails that allow visitors to experience its unique geology up close.
Many trails are relatively short, making the park accessible for visitors of all ages.
Human history is just as important as geological history within the park. Archaeologists have documented hundreds of ancestral Puebloan sites throughout the area, including petroglyphs, pit houses, and masonry structures. One of the highlights is Agate House, an eight-room pueblo originally built from petrified wood rather than traditional stone. These sites offer a glimpse into the lives of people who lived in the region more than 700 years ago.
Petrified Forest National Park is the only national park where visitors can see an original section of historic Route 66 running through its boundaries. A vintage automobile marks the location of the old highway, providing a popular photo opportunity and a reminder of America’s classic cross-country road trips.
Although the landscape may appear harsh, the park supports a surprising variety of wildlife.
Many animals are most active during the cooler morning and evening hours.
The park is open year-round, but spring and fall generally offer the most comfortable temperatures for hiking and sightseeing.

Petrified Forest National Park is far more than a collection of fossilized trees. It is a place where visitors can walk through landscapes that tell stories spanning hundreds of millions of years, from ancient forests and prehistoric animals to Indigenous cultures and the heyday of Route 66.
