Description:
One of the defining landmarks of Hawaii is this ancient volcanic crater which dominates over Waikiki. An observation deck at the top offers breathtaking views of the southern coast of Oahu - after driving through a short tunnel, you can hike up a 0.75 mile (1.1 km) trail from a parking lot in the crater to the rim, up a couple flights of stairs, through a tunnel (bring a flashlight) and an old coastal artillery to the summit.
