Home to the state capitol and the majority of Hawaii's population, the island of Oahu is a vibrant mix of natural, cultural and historic wonders. In Honolulu, an array of cultures blends harmoniously, allowing each to retain its distinct flavor. The downtown sector combines Hawaii's royal history with the modern-day action of a major metropolitan center. Waikiki Beach, with its impressive hotels and glittering atmosphere, is a famous tourist hub and resort destination of international renown. Honolulu is also the location of Diamond Head, Oahu's famous volcanic landmark, and Pearl Harbor, the largest natural harbor in Hawaii and the only naval base in the United States to be designated a National Historical Landmark.
