Yes, you can pull a camper through Petrified Forest National Park. The park's main road, Park Road, is paved and well-maintained, making it accessible for RVs and trailers. There are no size restrictions on vehicles, but be aware that some parking lots and turnouts may be limited in size and may not accommodate larger RVs or trailers. However, there are no campgrounds within the park itself, so you will need to find camping options outside the park. You can browse options on Hipcamp. Just remember to check the specific campground's RV and trailer size limitations and amenities before making a reservation.
