Honolulu, the capital of Hawaii and the seat of Honolulu county, is a cosmopolitan city. Its name means "protected harbor," and it serves as the crossroads of the Pacific Ocean with ship and air connections to the U.S. mainland, Asia, Australia, and New Zealand. The city is the principal port for the Hawaiian Islands and an important center for military defense with several bases, including Pearl Harbor Naval Base, located in the area. Millions of visitors are drawn annually to Honolulu's mild, semitropical climate and to the beautiful beaches of Waikiki.
