This is a strange park. It is a National Park but the only land the park has is an old house used for a VC and there are no petroglyphs on the property. The state of Arizona owns some but Albuquerque owns most of the sites. They do little to protect them, this is an urban area 17 miles long with several thousand petroglyphs. They also prevent the NPS from patrolling the site in any fashion. So you arrive at the VC with a sign telling you there are no trails or petroglyphs here and you go to a site where they are and there is a NP sign but nothing else. A mess of sorts. We only visited one site plus the VC. They are less than impressive except for the general idea of age and the numerous symbols. The rocks are jumbled all up and down small hills and you walk among them on a path or a boardwalk. The petroglyphs are generally faded and most are hard to see. Sort of expected with scratches on the rocks that are 100’s of years old.
