Petrified Forest National Monument has been a long time favorite of visitors into Arizona. Now there are many new adventures and discoveries as the Park has opened up new areas for backcountry hikes into Red Basin and little known areas like the Martha's Butte. There are also new exhibits in Rainbow Forest Museum to transport you to the Triassic Period. Stop at Painted Desert Visitor Center, Painted Desert Inn National Historic Landmark, or the Rainbow Forest Museum to plan your visit or to view the modern human history or paleontological exhibits.
