What is a diamond head?

Diamond Head (known by Native Hawaiians as *Lēʻahi*) a volcanic tuff cone on the south coast of the island of Oʻahu formed from a single volcanic eruption of rapidly cooling viscous magma from roughly 300,000 years ago.[a]

A popular hiking destination with stunning view. The hike to the summit offers panoramic views of Waikiki and the rest of O'ahu coast line. Hikers must climb to reach a lookout with scenic, near-vertical drop into the sea and views overlooking Honolulu and Waikiki and then up through an underground bunker in order to continue to the true 761 foot summit for spectacular panoramic views in nearly every direction, including Koko Head Crater
