More Information on Diamond Head
State Monument Tours
Diamond Head (Le‘ahi) crater, one of Hawaii’s most recognizable landmarks, was formed about 300,000 years ago after a single eruption sent ash and fine particles into the air. These materials cemented together to form the rock that makes up the crater. The trail to the summit of Diamond Head was built in 1908 as part of Oahu’s coastal defense system. Today, Diamond Head State Monument is Oahu’s third largest visitor attraction, with over 900,000 annual hikers.
For decades, visitors have hiked to the summit of Diamond Head to enjoy the incredible views of Oahu’s southeastern shoreline from Koko Head to Waianae. This popular historical trail offers a memorable Hawaiian adventure for the entire family. Diamond Head State Monument, managed by the State of Hawaii Department of Land and Natural Resources, Division of State Parks, is comprised of more than 475 acres of land, including the interior and outer slopes of the crater as well as the hiking trail.
The 0.8-mile hike (1.6 miles roundtrip) to the summit of Diamond Head State Monument is steep, strenuous and uneven in some areas. There is a total of 327 concrete and metal stairs along the trail. Please plan 1.5 to 2 hours for your hike. The weather inside the crater is usually hot. Sturdy walking shoes, water, hats, and sunscreen are recommended.
