Free to visit the grounds and wander the museum, gift shop and snack bar; $37 to take the tram and ride up while other and less expensive options are available. National Park security is in effect so be prepared for more than TSA screening. Live cameras from the top of the arch are in the museum. Outside area is pretty cool with the grand staircase.and ponds, all right on the river front. Parking will run from 6 to 10 bucks, depending on how close you want to get but you will still walk close to a half mile to and from the parking areas.
