It is the most populous island in Hawaii, with 75% of the state in residence; and it is home to the capital city of Honolulu with its tourist hub of Waikiki. But more than 90% of Oahu, believe it or not, is green space. The verdant Manoa Valley, the acres of agricultural land, the rainforest inland of the North Shore… Then there are the charming beach towns of Haleiwa—which catches international attention every winter when the big waves hit—Kailua, where many well-to-do residents live, and Ko Olina on the Leeward side of the island, a formerly quiet community that’s soon to see vast change due to Disney’s imminent Aulani Resort opening.
