One of Honolulu’s most iconic landmarks, Diamond Head State Monument — known as Lēʻahi in Hawaiian — is a massive volcanic crater that offers some of the best panoramic views on Oʻahu. The hike to the summit is short but rewarding, taking you through tunnels, old military bunkers, and steep staircases before opening up to breathtaking views of Waikīkī, Honolulu, and the endless Pacific Ocean.
