The Arizona Memorial program is  75 minutes long. The shortest tour to Pearl Harbor is the 4-hour Pearl Harbor Excursion. All of the other tours include this program, but add other sites such as the Battleship Missouri, Bowfin Submarine, and the Pacific Aviation Museum. Those Pearl Harbor Tours last from 6 to 13 hours. Pearl Harbor can also be visited as part of an Oahu island tour. For those who are only mildly interested in WWII history, but want to see the island, we recommend the Pearl Harbor & Oahu Island Tour. That tour spends approximately 3 hours at Pearl Harbor. Other, similar Combo Tours are available. For more information on how long it takes to tour Pearl Harbor, check out the individual Pearl Harbor Tours.
