By Ferry in Battery Park
There is a ferry that departs from Battery Park. https://www.statuecruises.com
Do not! Do not! Listen to the scammers wearing the red shirts. Their tours only go around the base of the statue. The only tickets you can get to visit the base and then Ellis island are sold by the national park services at Clinton Castle, the brown building in the south end if Battery Park.
Go to Battery Park before 1:30 pm, buy tickets inside the brown building, Clinton Castle. After that, head to the pier lines, there will be parks personnel dressed in brown uniforms which will point these to you. Have fun!
