Long Island extends east of New York City. This island has a varied landscape and many interesting communities, beaches and state parks. Visit the famous Hamptons and the stunning Fire Island National Seashore. Experience Long Island's extended coastline via kayak or canoe tour. Lighthouses are a popular draw in the area, and include the Montauk Point Lighthouse, the oldest such structure in the state and still in use as a navigational aid. For cultural entertainment, the Gateway Playhouse is a musical playhouse that offers productions from May to September. For the scientifically curious, the Vanderbilt Planetarium in Centerport fosters the education of those interested in the cosmos. William Vanderbilt, for whom the planetarium is named, also built an estate on Long Island; the Eagle's Nest is open to the public for tours and houses many examples of the Vanderbilt fortune.
