Long Island is a place of intriguing opposites — rolling green hills and white sand beaches; colonial charm and modern sensibilities; a world away from it all that’s less than two hours from the biggest city in the U.S.
Long Island isn’t just a retreat for the rich and famous (although it is home to the mansions that collectively inspired F. Scott Fitzgerald’s “The Great Gatsby”), but it has become a destination for those seeking an elegant seaside getaway, cultural events, historic places, and so much more.
If you’re planning an excursion to Nassau County on Long Island, we’ve put together a list of some fun day trip destinations for you to explore.

1. Old Westbury Gardens
Experience one of Long Island’s opulent mansions for yourself at Old Westbury Gardens. John S. Phipps built this home for his fiancée in 1906, modeled on architecture from the English Caroline era. This sprawling estate is now open to the public and features manicured grounds, forests and ponds, and a home full of fascinating antiques.
2. Old Bethpage Village Restoration
Get a look at what life on Long Island in the 1800s. A collection of homes and buildings originally from around the island now form Old Bethpage Village Restoration.

During some weekends, you might even catch special events like an old-fashioned baseball game or Halloween celebrations.
For a swanky shopping experience, venture to Americana Manhasset for boutiques and designer wares of all kinds. You’ll find Prada, Tiffany & Co., Hermès, and more, as well as plenty of restaurants. Window-shopping or splurging are both great ways to pass the time here.

An educational experience awaits when you visit one of the three museums here: There’s the Long Island Children’s Museum, the Nassau County Firefighter’s Museum, and the Cradle of Aviation Museum. Nearby is also the restored Nunley’s Carousel, originally constructed in 1912, for fans of old amusement rides.
