History


Formed by a giant shield volcano which began erupting more than 2.5 million years ago, the now dormant Koolau Volcano has erupted within the last 100,000 years. These recent eruptions have made some of Oahus most signature landmarks like Diamond Head Crater and Hanauma Bay.

Appropriately named by the ancient Hawaiians, Ko’olau translates into “Windward” in English. The mountain range has suffered much erosion due to it’s exposure to winds and rain.
