hiking diamond head crater (le-ahi) – a challenging & rewarding oahu adventure
Diamond Head may not be the most extreme hike on O‘ahu, but it’s definitely challenging enough—especially under the Hawaiian sun. Think steep staircases, narrow switchbacks, and a nearly two miles round-trip. But the payoff is unbeatable—a panoramic summit view of Waikiki, Honolulu, and the Pacific coastline.
