In many ways much more Asian than American, Honolulu is Hawaii's largest city and its center of government, transportation, commerce, and tourism.
Escape the urban bustle at Waikiki Beach and Hanauma Bay Nature Preserve. Get some cultural insight at Battleship Missouri Memorial and Iolani Palace. Explore Honolulu's surroundings by going to Dole Plantation (in Wahiawa), Kailua (Kailua Beach Park & Lanikai Beach), Polynesian Cultural Center (in Laie) and Haleiwa (Sunset Beach Park & Waimea Bay). And it doesn't end there: take in the pleasant sights at Diamond Head State Monument, tour the pleasant surroundings at Kapiolani Regional Park, see the interesting displays at USS Bowfin Submarine Museum & Park, and take a memorable drive along Makapuu Point.
