Parking is available at visitor center? How much is parking? And how much is trolley?

Parking in garage at visitors center 15.00 dollars for day. If you leave you can not re-enter garage unless you pay again....46.00 for trolley. There is more parking available with meters. Hope this helps

There is a parking right across visitor center. I do not remember how much we pay but is was not expensive. About trolley ,it depends .I remenber there was at least 2 companies that has it.

The trolley I think is around 40 bucks

Yes, theres parking.
