Visit Long Island/Islip MacArthur

When you deplane at Long Island MacArthur Airport, adventure is only a Long Island Railroad (LIRR) ticket away. Or grab a rental car and take full advantage of the options available to you by arriving at this conveniently located Long Island airport. While your final destination may be the Big Apple or the Hamptons, consider making time to explore Suffolk County before you get on your way. Lighthouse lovers, take note: Suffolk County is home to more lighthouses than any other county in the States, including the landmarked Fire Island Lighthouse inside Fire Island National Seashore.


If you’re heading into the city, you’re just an hour outside of Queens by car—perhaps a bit faster on the LIRR. Don’t skip this borough in favor of Manhattan, though; this culturally diverse area is home to more linguistic diversity than anywhere else on earth, and the range of things to do reflects this. Several cultural institutions—from art galleries and graffiti exhibits to history and science museums—are dedicated to the unique cultures that call Queens home. Consider exploring the Afrikan Poetry Theatre, the John Browne House, the Museum of the Moving Image, or the Isamu Noguchi Foundation and Garden Museum before you leave the borough.
