Long Island is famous for beaches, bagels, and Billy Joel. It's also home to beautiful sights like the Oheka Castle, Montauk lighthouse, and the Vanderbilt estate. Just like its namesake Long Island iced tea, this place has a lot of different elements all in one place.

Long Island is a densely-populated island in the southeastern geographical area of the U.S. state of New York; it is also part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the 18th-most populous in the world. The island begins at New York Harbor approximately 0.35 miles (0.56 km) east of Roosevelt Island and extends eastward approximately 118 miles (190 km) into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four counties; Kings and Queens counties (the New York City boroughs of Brooklyn and Queens, respectively) and Nassau County share the western third of the island, while Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens.

Culturally, many people in the New York metropolitan area colloquially use the term "Long Island" (or "the Island") to refer exclusively to Nassau and Suffolk counties, and conversely, employ the term "the City" to mean Manhattan alone. The Nassau-and-Suffolk-only definition of Long Island is recognized as a "region" by the state of New York. Although geographically an island, the Supreme Court of the United States has held that given the island's extensive ties to the mainland, it should be treated like a peninsula, allowing the state to have jurisdiction within its maritime boundaries.
