Diamond Head, Hawaii

Diamond Head.

This extinct volcanic tuff cone stands guard over Waikiki and is O’ahu’s signature background. You can hike to the top in about an hour or less– a paved path leads 1.3 km (0.8 miles) all the way to the top, which at 232 m (760 feet) affords some quite incredible views of Waikiki. (OK, you’ll still have to see a beach. However, you won’t have to step on it. Delighted?).
