Diamond Head State Monument

Diamond Head State Monument is one of Hawaii’s most recognizable landmarks, known for its historic hiking trail, stunning coastal views, and military history. It is a symbol of the Hawaiian Islands’ natural beauty and a must-visit for anyone traveling to Oahu.

About the Place

The monument encompasses over 475 acres, including the interior and outer slopes of the crater. It is a tuff cone, which is a type of volcanic cone formed by the accumulation of volcanic debris. Diamond Head is a defining feature of the geography of Waikiki and the Honolulu area.

History

Diamond Head is estimated to have formed about 300,000 years ago from a single, explosive eruption. The crater was named “Diamond Head” by 19th-century British sailors who thought they had discovered diamonds on the crater’s slopes, which turned out to be calcite crystals.

The area played a significant military role as a lookout post for the United States Army during the 20th century, with bunkers and observation stations built into the crater walls. It was declared a National Natural Landmark in 1968.
