Diamond Head State Monument is a scenic attraction in Oahu, Hawaii.

# data[].attributes.attachment_link.readable_text
Diamond Head is a volcanic cone on the Hawaiian island of Oahu and is the most popular Hawaii State Park. Hawaiians call it Lēʻahi (brow of the tuna) in reference to the formation's ridgeline, which resembles the tuna fish's dorsal fin. The British soldiers who visited the area in the 19th century thought that the sparkling calcite crystals on the neighboring beach were diamonds.

Diamond Head offers stunning views of the Pacific Ocean and Honolulu that you can hike to via a trail that takes you to the edge of the 300,000-year old crater.

An entry fee of $1 per walk-in visitor and $5 per vehicle applies.

What is Diamond Head?

Diamond Head is part of the Ko'olau Range of volcanoes that began erupting below sea level over 2.6 million years ago. A single eruption around 300,000 years ago created the crater.

The crater encompasses 350 acres. The crater is much larger than its rim as it was formed explosively. This type of formation is known as a tuff cone.

Diamond Head stands at an elevation of 762 feet above sea level. When measured from the crater floor, the Diamond Head Mountain towers to 560 feet.

Diamond Head is monogenetic, which means eruption occurs only once. The last eruption of the volcanic tuff cone was likely 150,000 to 200,000 years ago. It has remained dormant since.

What's the Military Significance of Diamond Head?

The U.S. government purchased the Diamond Head Crater and some of the surrounding areas in 1905, and developed around 720 acres into Fort Ruger, as a way to strengthen the country's coast artillery defense. It was Hawaii's first U.S. military reservation. Batteries and guns were installed on the slopes of the crater and inside it. Post World War II, the facilities were upgraded, including the addition of anti-aircraft batteries to the crater's rim.

Today, some of these installations remain. They include Battery 407, which was originally envisioned to mount guns salvaged from the USS Arizona; Birkhimer Tunnel, a bunker style battery; a National Guard emergency operations center; and the Hawaii State Civil Defense Headquarters.

The seven tunnels constructed into the crater's outside slope have been used by a number of agencies. Tunnel 0 is used for communication and others (Tunnels 1 to 6) serve as storage areas. Many of the tunnels have ventilation systems.

What is there to do at Diamond Head State Park?

There aren't many places in the world where you can hike to the edge of a volcano. The Diamond Head Trail allows this opportunity, which culminates in panoramic views of Oahu, the famous Diamond Head Lighthouse, a United States Coast Guard facility that has been featured on a U.S. postage stamp, and the beautiful Pacific Ocean. On a clear day, you can also the nearby island of Molokai.

Built-in 1908 as part of the army coastal artillery defense system, the trail scales the inside slope of the crater for 0.6 miles. It is a switchback trail with the mountain on one side and a railing on the other. The dirt trail was built to allow the movement of people and mules hauling material for the construction of a fire control station. In 1940, the Kahala tunnel was constructed and serves as the entrance to the crater.

There is a rest stop at a lookout point, and then you'll make your way through tunnels and stairs. Climb 99 steps to get to the second lookout point where you'll find a WW II bunker. A further 54 steps from there will bring you to the crater's summit.

The crater rim houses a picnic area, restrooms, drinking fountains and information and historical displays.

A number of beaches and parks are in the proximity of the volcano.

How long does it take to hike Diamond Head?

It takes about 1.5-2 hours to hike Diamond Head (1.6 miles (2.5 km) roundtrip).

The paved surface and handrails make your hike safe and convenient. Still, some parts of the trail comprise of uneven rock, so make sure you walk carefully and don't lose your footing. Note that you have to walk through a narrow tunnel on your way to the summit. If you're claustrophobic, this may feel a tad uncomfortable, but you'll be out soon and be rewarded with majestic views!

Also, exercise caution when ascending the 99 steps at the end of your hike. Wear good hiking shoes. And to be extra cautious, bring along a flashlight so you can watch your steps.

Spring and winter are busy tourist seasons. Fall weather is pleasant to visit the volcanic formation but rainfall and snow may play spoilsport.
