Depends on what you want to do. You can go on a ferry ride around the statue etc or you can go on a ferry and get down in the island, walk inside & climb on top of the statue. Online booking is cheap & seperate small line for the ferry.
Approx 25.00, more if you wish to do the crown, then its about 30.00. If you book online, theres fees but gives you priority line.
I didn't go up to the base. Just took the ferry out and walked around it.
