Yes, multiple ferry services connect various points to Long Island, New York, in 2026. The most famous "inter-state" routes are the Cross Sound Ferry, which runs between New London, Connecticut, and Orient Point, Long Island, and the Bridgeport & Port Jefferson Ferry, connecting Bridgeport, Connecticut, to Port Jefferson. Within New York City, the NYC Ferry system offers the "Rockaway Route" and the "Astoria Route," which provide water transit to the southern and western shores of Long Island (specifically the boroughs of Queens and Brooklyn, which are geographically part of the island). For those traveling to the eastern end, the North Ferry and South Ferry connect Shelter Island to the North and South Forks of Long Island, respectively. It is important to note that the "Staten Island Ferry" does not go to Long Island; it only travels between Manhattan and Staten Island, which is a separate island entirely.
