If you're a WWII history fan, and especially if you're already at Pearl Harbor to visit the USS Arizona Memorial, it's well worth your time to hop on the free shuttle bus over to Ford Island and tour this retired battleship. On these decks, Japan formally surrendered to end WWII, and when you're standing here you can also see the sunken USS Arizona Memorial that originally propelled the USA into war with Japan, so (as one retired military vet who was my tour guide pointed out) these two attractions are like the bookends of WWII.
