About: Diamond Head State Monument
Diamond Head is a volcanic tuff cone and state monument located on the Hawaiian island of Oahu. The stunning views that it offers down over Honolulu and the Pacific Ocean attract large numbers of tourists each year. The views are so good that it was used a strategic lookout by the US Military during the 1900s.
