Our visit to Petrified Forest National Park was part of our road trip to the southwest region from three years ago. When we got there, it’s closed to 4 pm. and we weren’t sure what time it got dark. There are two entrances to this park: South Entrance and North Entrance, and the distance from one end to the other end are 28 miles (45 km) that takes about an hour of driving. Since we came from Tucson, we entered through the South Entrance.
