Diamond Head Crater
is a distinctive volcano landmark located at the end of Waikiki Beach
. The crater marks the edge of South Shore Oahu
. In Hawaiian, the famous mountain is called “Le’ahi”, because it resembles the forehead (lae) of the tuna (ahi). Diamond Head Crater
is a cinder cone volcano that erupted briefly during its early stages of existence.
British sailors mistook calcite crystals found here for Diamonds and called the mountain Diamond Head. Although Oahu’s Ko'olau Mountain Range is over 2.6 million years old, Diamond Head is estimated to be over 200,000 years old.
