I had my reservations about going here. I thought would see the park in 20-30 minutes. We took almost three hours to drive the 25 miles through the park. Some areas are very austere, however the OTHER areas more than make up for it. The Petrified Forest is NOT a bunch of rocks laying around. (Ok there are plenty of those too) but awe inspiring views and colors that will blow you away. Please, if you are traveling Route 66 (I-40) and you are near Holbrook AZ, you will not be disappointed.
