Its quite a trip out there but so very worth it if you wanna have the very special beach-experience! You can go there by car and then take the ferry either to Pines or Cherry Grove (I would prefer Pines!) or you do all by public transportation - there a "getaway tickes" for 36Dollars and the transfer works really smooth - may even be faster than by car!
A beautiful and abandoned New York subway station from 1904, complete with chandelier. Take the 6 train heading downtown. When the train makes its final stop at the “Brooklyn Bridge/City Hall” station, passengers are told to exit the train. Stay on the train and duck down so as not to be easily spotted. When the train departs the station, it will pass through the abandoned City Hall Station.
