Diamond Head State Monument Description

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.
