Things to do at Diamond Head

Diamond Head is the extinct volcanic cone that frames Waikiki's eastern skyline, now a state monument with a hiking trail to the crater rim. Out-of-state visitors must book a timed entry in advance through Hawaii's state parks reservation system, with separate fees for pedestrians and vehicles. 5 to 2 hours round trip with no shade.

Arriving soon after the gate opens beats the midday heat and the parking crunch. From the rim, the payoff is a wide view over Waikiki's hotel towers and the open Pacific.
