Pets on a leash no longer than 6 feet are allowed in Petrified Forest National Park on any paved road or trails, even in wilderness areas. Located in Navajo and Apache counties in northeastern Arizona, the park is known for its fossils, especially fallen trees that lived in the Late Triassic, about 225 million years ago. Pets are not allowed in park buildings.
