10. Shooter’s Island (Kill Van Kull)
This 43-acre island straddles the border between New York and New Jersey and derives its name from the hunting activities that took place here during the Colonial Era. As New York grew as an industrial port, the island accommodated an oil refinery and shipyard during the 19th century. Today, the island is owned by the Department of Parks and Recreation, with the Audubon Society managing wildlife research. Many prominent historical figures from George Washington to Theodore Roosevelt and Prince Henry of Prussia once made great use of the island, with the former utilizing it as a location to drop off covert messages during the Revolutionary War.
