• Hike a trail up to the top of the crater at Diamond Head, a volcanic tuff cone, and delight in the breathtaking views of the Pacific Ocean and Honolulu. Diamond Head, a U.S. National Natural Landmark, was given its name by 19th-century British sailors who mistook calcite crystals on the adjacent beach for diamonds.

• Gaze at the portraits of Hawaiian royalty, ornate furniture, and the beautiful koa staircase at the Iolani Palace, the former royal residence of the Kingdom of Hawaii and the only royal palace in the United States.

• Visit the Pearl Harbor National Memorial, which marks the final resting place of the USS Arizona and the more than 1,000 sailors and Marines who were killed during the attack on Pearl Harbor. Designed by Honolulu architect Alfred Preis, the memorial consists of a curved bridge floating above the battleship that represents the height of American pride before the war, the nation’s sudden depression after the attack, and the rise of American power to new heights after the war.
