The Formation of Diamond Head

Diamond Head is also known as Le’ahi. It’s broad, saucer-shaped crater was formed about 300,000 years ago during a single, explosive eruption. The eruption sent ash and fine particles in the air. As these materials settled, they cemented together into a rock called tuff, creating the crater. It is visible from the trail in the park. Most of the vegetation and birds were introduced in the late 1800s to early 1900s.

A Little History

The name “Diamond Head” comes from the 19th century when British sailors mistook calcite crystals found in the crater for diamonds. The name stuck and has been used ever since.

Throughout history, Diamond Head has played a significant role in Hawaiian culture and military history. The crater was once used as a navigational landmark by Hawaiian seafarers. It was also a sacred site where the Hawaiian god of fire, Pele, was believed to live in the early 1900s.  The US military later established a coastal defense system at Diamond Head to protect the island from potential attacks.
