The trail to the summit of Leʻahi (Hawaiian name for Diamond Head Crater) was built in 1908 as part of Oʻahu’s coastal defense system. Completed in 1911, the Fire Control Station at the summit directed artillery fire from batteries in Waikiki and Fort Ruger outside Diamond Head crater. The walk is a glimpse into the geological and military history of this volcanic crater. Much of the trail is a natural tuff surface with many switchbacks traversing the steep interior slope of the crater wall. The ascent continues up steep stairs and through a lighted 225-foot tunnel. At the summit, you’ll see bunkers on the crater rim and a navigational lighthouse built in 1917 along the coast outside the crater. The postcard view of the shoreline of southeastern Oʻahu from Koko Head to Wai’anae is stunning, and during winter, may include passing humpback whales.
From the parking lot on the crater floor, the trail to the summit is 0.8 mile (1.3 km) one way and climbs 560 feet (171 m) in elevation. There is a paved concrete walkway for a distance of 0.2 miles at the start of the hike, but the trail becomes uneven and steep, requiring caution and appropriate footwear. Portions of the trail involve steep stairways – take your time. Another portion of the trail goes through a long, narrow tunnel which is lighted.
The trailhead is adjacent to the parking lot within Diamond Head State Monument. The entrance is off Diamond Head Road between Makapu’u Avenue and 18th Avenue, Honolulu. See park page for fees. (Click Here)
