Diamond Head overlooks the one-square mile historic community of Waikiki and the endless summer of world-famous Waikiki Beach.  After your descent from the scenic overlook, take some time to first explore local favorite Kapahulu Avenue on the east side of Waikiki. This is one of the best areas on the island to antique shop and grab a bite of local grinds (food).  Informed visitors search for the perfect vintage Hawaiian shirt and other kitschy souvenirs at the always fun Bailey's Antiques and Aloha Shirts (517 Kapahulu Avenue).
