Welcome to Nassau County, Long Island. "The Island of Possibilities." I am incredibly proud of Nassau County, an exciting and dynamic place to visit, just steps from New York City. We look forward to your visit to experience and enjoy our natural beauty, our rich history and our many attractions. Nassau County is less than 20 miles from Times Square, the Crossroads of the World, easily reached by car or the Long Island Rail Road, and less than a half-hour ride from LaGuardia, Kennedy and MacArthur airports. Come enjoy our acres of beautiful white sand beaches on the Atlantic Ocean and miles of rugged coastline on the tranquil Long Island Sound. And in-between, discover our charming villages and downtowns, fascinating and kid-friendly museums, world-class shopping, top-notch hotels and restaurants, scenic hiking trails, picturesque public gardens, bike paths, swimming, surfing, boating and fishing. Plus, there are plenty of free and near-free events and attractions all year long. All this just a quick trip from Manhattan or from the east via the ferries from Connecticut. Visit for the day. Or stay for the night at one of our terrific hotels. Again, I welcome you to Nassau County and wish you safe and pleasant travels. Nassau County Executive Edward P. Mangano
