Diamond Head Crater

One of the most famous landmarks in Hawaii, Diamond Head dominates the landscape over Honolulu. Officially termed an extinct volcanic tuff cone, the mammoth cone is a US Monument and a popular attraction on Oahu. Located near resorts and beaches in Honolulu, Diamond Head has a hiking trail that takes roughly two hours to complete; while the trail is uneven and includes nearly 200 steps, the view of Oahu from the summit is well worth the effort. Note that hikers should bring plenty of water and protection from the heat, as there are no facilities along the trail, and the only comfort station is located at the base of the crater.
Address: Off Diamond Head Road Between Makapu'u Avenue and 18th Avenue
