The 20-30 minute wait in line to take the elevator to the top of this Memorial is time well spent. You wait on steps that wind up about one story through a white-tiled staircase that makes it feel as though you're inside a nautilus. The Rangers who work here are all very cordial and well informed, sharing the history of the island and the meaning behind the memorial. The view from the top of the tower is PHENOMENAL. Highly recommend!
