And this is the Diamond Head history of the volcano eruption, as told by the State of Hawaii
There was an explosive volcanic eruption on the flanks of the Ko’olau Mountains on Oahu around 30,000 years ago. During this eruption, there were large amounts of ash and fine particles that were sent into the air. As the particles settled around the center of the eruption, a crater was created.
What crater did the volcano eruption create?!
That’s right — the Diamond Head Crater!
When the ash and fine particles settled, they were cemented into rock called tuff. This means that Diamond Head is a tuff cone. Other tuff cones on Oahu from around the same time period include the Punchbowl Crater and Koko Crater. Along with the Diamond Head hike, the Koko Head hike is another good (and more strenuous!) hiking trail!
Diamond Head’s highest point is at 761 feet. It’s on the seaward rim and reflects the windblown buildup of ash at the time of the eruption.

Erosion of the Diamond Head Crater
Since the formation of Diamond Head, the slopes of the crater have been eroded by rain, wind, and the ocean waves.
This is what gives the crater the shape that it is today.
A coral reef now helps to protect the seaward slopes of the the crater.
When you go for the summit, hike on the marked Diamond Head Trail
Part of what contributes to the erosion of Diamond Head Crater is the millions of hikers who walk through the crater each year.
As tempting as it is to go off the marked trail when you see everyone else doing it, you can help to slow the erosion by staying on the marked trail.
Monkey see, monkey… don’t do 😉
