I didn't even plan to go here but it was close by to a planned event (Pacific Roller Derby!). It is an old crater now made into a green, quiet, huge cemetery. Once you explore the graves, you can climb majestic stairs up to a pure white statue honoring those who are buried there (including the unnamed); you may be accompanied by a carillon. There are informative frescoes and information about Pearl Harbor at the top. Lastly, don't miss walking all the up to the overlook. It's a marvelous 360-degree view of Honolulu, the Pacific Ocean and the mountains.
