The Island of Oahu
Oahu, known as "The Gathering Place", is the third largest of the Hawaiian Islands and the most populous of the islands in the U.S. state of Hawaii. The state capital, Honolulu, is on Oahu's southeast coast. Including small close-in offshore islands such as Ford Island and the islands in Kaneohe Bay and off the eastern (windward) coast, it has a total land area of 596.7 square miles (1,545.4 km2), making it the 20th largest island in the United States. In the greatest dimension, this volcanic island is 44 miles (71 km) long and 30 miles (48 km) across. The length of the shoreline is 227 miles (365 km). The island is the result of two separate shield volcanoes: Waiʻanae and Koʻolau, with a broad "valley" or saddle (the central Oʻahu Plain) between them. The highest point is Mt. Ka'ala in the Waiʻanae Range, rising to 4,003 feet (1,220 m) above sea level.
The city of Honolulu—largest city, state capital, and main deep water marine port for the State of Hawaiʻi—is located here. As a jurisdictional unit, the entire island of Oʻahu is in the City & County of Honolulu, although as a place name, Honolulu occupies only a portion of the southeast end of the island.
Well-known features found on Oʻahu include Waikīkī, Pearl Harbor, Diamond Head, Hanauma, Kāneʻohe Bay, Kailua Bay, North Shore.
