Diamond Head, locally known as Lēʻahi, is a volcanic tuff cone formed approximately 400,000 to 500,000 years ago as part of the Honolulu Volcanic Series. This iconic natural landmark overlooks Honolulu and Waikīkī, offering visitors a unique blend of geological wonder and historical significance. The crater was once home to Fort Ruger, the first U.S. military reservation in Hawaii, and still contains military installations like Battery 407 and the Birkhimer Tunnel. A popular 0.8-mile trail, originally built in 1908 for military coastal defense, leads to the summit where visitors can explore old bunkers and enjoy sweeping views of the island's south shore. Designated a U.S. National Natural Landmark in 1968, Diamond Head remains a symbol of Hawaiian natural heritage and a favored hiking destination, combining stunning scenery with cultural depth. Its proximity to Honolulu's beaches and resorts makes it easily accessible and a must-see for visitors to Oʻahu.
