Diamond Head – Best-known Volcanic Crater

Diamond Head is one of the primary icons that Hawaii is known for. This majestic giant volcano towers above the Waikiki beach area and can be seen for miles.

Diamond Head’s visual prominence also benefits from Hawaii’s weather. The clear air and low clouds set off the shape the way a frame promotes a picture. “In Hawaii you see sharp, dense shadows and sparkling highlights on the landscape, and that helps define it as well.”

Government-owned, Diamond Head served over the years as a training ground and revetment for the military, rarely open to the public except during occasional music festivals. That has changed, and the two-hour hike to the 760-foot summit has become one of the most popular outings in the islands.

On the rim, visitors can also inspect the tunnels and sighting apertures dug out by the Army, when the peak was an important part of Fort DeRussy’s artillery system.

Diamond Head is a kind of logo for Hawaii, said artist Pegge Hopper. “The sheer shape of it is so iconic. A great crutch for beginning artists; if you had to ship out a label for anyone. Diamond Head, a hula girl, plumeria lei, a coconut tree — mix them together in any combination, and you have a logo that’s distinctly Hawaii.”

Diamond Head is also the name of a British heavy metal band and of a Charlton Heston movie, of a comic-book villain and of a tiny Southern hamlet. But the Hawaiian locals feel that Diamond Head is simply the best-known volcanic crater in the universe. Amen.




Diamond Head State Monument, Oahu

Diamond Head State Monument

Diamond Head is Hawaii’s most famous landmark. Known in Hawaiian as Le’ahi, so named by Hi’laka, the sister of the fire god Pele, because the summit supposedly resembles the forehead (lae) of the yellowfin tuna fish (‘ahi). It wasn’t until the late 1700′s, when western traders thought they had found diamonds on the slope of the crater, that they began to call it Diamond Head.

But before you head to the Diamond Head State Monument to dig for diamonds, you should know that (to the disappointment of the western explorers and traders) the so-called diamonds were merely calcite crystals, worthless to mine.

The must-do at the Diamond Head State Monument is the short hike through old military bunkers. (Bring water and a flashlight.) The historical trail to the summit is an easy 1.4 mile hike that climbs an elevation of 560 feet and ends with sweeping views of the Honolulu area.

There are handrails, plenty of places to rest, and places of interest, so allow 1.5 to 2 hours for a leisurely round-trip hike. Also, bring a flashlight because portions of this trail go through long, dark tunnels. Amazingly, some locals and visitors jog up and down Diamond Head for exercise.

To get to the access road to the trail, follow Kalakaua Avenue to Kapiolani Park. Go north on Diamond Head Avenue to 18th Avenue.
