Youth under age 18 must be with an adult to be admitted into the rock area. The earlier that you arrive, the better. The fair and scenic area open at 11AM, and most everything starts at that time. The rock area is less populated then. And, the available parking is closer.
Some parking is possible along most of the nearby roads.
If all of the parking up on the hill by the park is filled, some patrons park along the streets of the village, just below the rock formation. The roads need to be kept clear for emergency vehicles. We cannot prevent ticketing of illegally parked vehicles. We now have modern restrooms. There are even sinks with hot water.
