Diamond Head is a volcanic tuff cone, known to Hawaiians as Lēahi, on the Hawaiian island of Oiddahu. More possibly, the Hawaiian name derives from lae (browridge, promontory) plus some ahi (tuna) because the ridgeline shape resembles the dorsal fin shape of a tuna. British sailors in the 19th century gave it its English name, mistook calcite crystals for diamonds on the nearby sand.
It was once an active volcano but for more than 150,000 years it hasn’t spewed any ashes. For many the extinct crater and lookout point at its peak is a popular hiking destination. In fact, Diamond Head is one of Oahu’s most photographed and painted spots, with many wall calendars and postcards adorning it.
In 1905, the US government bought the Diamond Head Crater and some of the adjacent land, converting 720 acres into Fort Ruger to enhance the country’s coast artillery defense. It was the first U.S. military reservation in Hawaii. On the crater’s slopes and within, batteries and weapons were erected. The facilities were updated after WWII, including the installation of anti-aircraft batteries on the crater’s rim.
Some of these structures are still in use today. Battery 407, which was built to house weapons recovered from the USS Arizona, the Birkhimer Tunnel, a bunker-style battery, the National Guard emergency operations center, and the Hawaii State Civil Defense Headquarters are among them.
A variety of entities have exploited the seven tunnels built into the crater’s exterior slope. Tunnel 0 is utilized for communication, while Tunnels 1 through 6 are used for storage. There are ventilation systems in several of the tunnels.
Diamond Head Crater is only a short car or bus ride away from Waikiki. This moderately difficult walk features two sets of stairs with a total of 175 steps, as well as dark underground tunnels and old military bunkers that necessitate the use of a flashlight. The breathtaking views from the summit of Diamond Head are definitely worth the effort.
If you want to walk on Saturday morning, don’t forget to stop by the Kapiolani Community College Farmer’s Market, which is located across the street from the monument entry on Monsarrat Avenue and features locally grown food and produce. In fact, Monsarrat is lined with noteworthy cafes and restaurants that provide for a superb pre- or post-Diamond Head lunch.
