Access the memorial sight via the free Park Service shuttle boats that run according to a timed ticket schedule. While some private Pearl Harbor boat tours include shuttle tickets and round-trip transportation from Honolulu and Waikiki, they're typically not allowed to disembark at the memorial and may cruise around it.
The Park Service’s USS Arizona Memorial tour includes a 23-minute documentary, round-trip boat ride, and time at the memorial. Plan to spend about 90 minutes there. Note that the park service releases a limited number of tickets each day Booking a tour in advance is a convenient way to ensure you’ll see the memorial.
