Free, but make sure you go to the visitor's center first to sign up for the free tour! We were able to take pics on the outside but didn't get tickets for the tour inside cause we didn't know, and we didn't want to walk back there and walk back! But outside pics on the porch are nice!
It's a free self-guided tour
Thank you both so much and sorry about the incorrect spelling of yours. Have a great day.
