Frenchman Island at Cicero, Cicero, New York.

Cool abandoned lighthouse, but can't go in it. The only way to the island is by boat or Kayak. Sometimes you can go in the Lighthouse and sometimes you can't. There's no bathroom and one area to dock your boat. Fun fact The lighthouses were built in 1917 as part of the New York State Barge Canal, which uses Oneida Lake as part of its water route from the Hudson River to Lake Erie.
