Diamond Head is the world’s most recognized volcanic crater. It was formed about 300,000 years ago during a single eruption. It is not made of lava flow but of ash and fine particles that settled and cemented together into a rock called tuff.
The 0.75 mile Diamond Head hike takes about 1.5-2 hours round-trip. The hike wasn’t difficult but it does take you over several trails, up 74 stairs, through a tunnel and then up 99 steep stairs. At this point you are almost there but you have to continue through another small tunnel and up a spiral staircase inside a coastal artillery observation platform. The stairs are tough but the view is worth it!

Ancient Hawaiians named it Laeahi which meant “brow of the tuna.” In the 1800s, the British sailors
named it Diamond Head because they thought the calcite crystals they saw glimmering in the sunlight were diamonds lodged in the crater.
The views were great throughout the Diamond Head hike – even when we first hit the trail!
We couldn’t wait to get to the top to take in the Oahu views!
A great photo opportunity before we hit the first set of stairs!
Diamond Head was purchased in 1904 by the US Government for military purposes. We enjoyed seeing the bunkers and the Fire Control Station.

It was cool walking through this tunnel!
The toughest part of the hike!
Crawling out the observation portion of the Fire Control Station completed in 1910. We were greeted by amazing views!
