largest privately owned island in the united states
Gardiners Island Gardiner's Island is a small island in the Town of East Hampton, New York, in Eastern Suffolk County. It is located in Gardiner's Bay between the two peninsulas at the East end of Long Island. It is 6 miles (9.7 km) long, 3 miles (4.8 km) wide and has 27 miles (43 km) of coastline. The island has been owned by the Gardiner family and their descendants since 1639 when Lion Gardiner purchased it from the Montaukett chief Wyandanch.[1] It is one of the larger privately owned islands in the United States, and is slightly smaller than Naushon Island in Massachusetts, owned by the Forbes Family.[2][3]
Oahu O‘ahu (pronounced [oˈʔɐhu], anglicized Oahu /oʊˈɑːhuː/), known as "The Gathering Place", is the third-largest of the Hawaiian Islands. It is home to roughly one million people -- about two-thirds of the population of the U.S. state of Hawai‘i. The state capital, Honolulu, is on O‘ahu's southeast coast. Including small associated islands such as Ford Island and the islands in Kāneʻohe Bay and off the eastern (windward) coast, its area is 596.7 square miles (1,545.4 km2), making it the 20th-largest island in the United States.[1]
