What is Diamond Head?
Diamond Head (Lēʻahi) is the volcanic crater that rises behind Waikiki, one of Hawaii's most recognisable landmarks. The Diamond Head Summit Trail climbs from the crater floor to the rim, through tunnels and up steep stairs, to old military bunkers and a lookout with sweeping views over Waikiki, Honolulu and the Pacific.
The trail is short but steep, about 1.6 miles round trip, climbing roughly 560 ft. There's little shade, and it gets very hot by midday.
