First FYI the trails do not lead to the rocks. The site is not marked well. Go to the second parking lot and you will be right beside the rocks. You can enter the walking tour there. If you park at the first lot where the amphitheater and concession stand is go to the far right of the side the lot go across the grass. That will only put you on top of the rocks. This is a very neat place. Not handicap accessible. No fees here absolutely free. Have fun.
