parked at the parking lot. the guy said no problem. no facilities but quiet except for sounds of nature. the road that leads to ruins ( 40km) is in very bad shape and LOW branches. I hit the solar panels a few times, so drive slow you have to watch for branches and potholes at the same time worth the visit !
