How much do you pay just for the entrance not the tour?

There is only one price. The audio tour is free with the prize of admission.

The audio guided tour is excellent.

If you show up and buy entrance, it includes the tour for free. Its an excellent guided voice tour so id recommend it anyways.

I think is is $16 at the door, but $14 if you pay online or showing AAA or AARP membership.

$13.00 per adult

i believe i paid 10 per person. not for the tour. i paid online though
