On December 7, 1941, a surprise air attack by the Japanese at Pearl Harbor plunged the United States into World War II and claimed thousands of lives. At Pearl Harbor, visitors can immerse themselves in five historic sites that make up the National Memorial. The Pearl Harbor Visitor Center is the gateway to the USS Arizona Memorial, USS Oklahoma Memorial, and USS Utah Memorial, among others. The USS Arizona Memorial is a place of somber beauty and reflection, the final resting place for over 900 sailors and Marines. You can also visit the USS Oklahoma Memorial, which tells the story of rescue and survival, and the USS Utah Memorial, which is the final resting place for 58 men and offers a deeper understanding of Pearl Harbor. Reserve a time slot for the boat tour to the USS Arizona Memorial, which is free, but you must reserve it in advance.
