Q: I haven't been able to get to battery park until now. The place I was checking into had it's last boat leave at 4:30. Are there any other options?
A: My friend, the last boat to Liberty Island from Battery Park does not leave until 5pm. Therefore, if you can not make it to the last boat, you can take the Staten Island Ferry, which goes Lower Manhattan to Staten Island.
It does not stop at Liberty Island, but it passes the Statue on ways to an from Staten Island.
Ride on the Staten Island Ferry is free.
