Instructions a couple miles past the state park pull off at the cell tower walk across 111 over two sets of train tracks and a mile straight across the desert. No one else is parked and the cell tower barely had enough room for a car let alone my rv, but there was something a little past that what could be a turn off. Now for the walk off into the desert and totally worth it!! Caves, rocks, cliff edges and of course caves! Tunnels, rooms and holes so much fun to investigate. Feels like a super cool playground only for the cool kids.
