Diamond Head, the iconic crater overlooking Waikiki beach, is a 475 acre state monument that draws many visitors interested in scenic vistas, grueling day hikes, or Hawaii’s military history. Located just thirty minutes from Ko Olina, the park is filled with thick vegetation, wild fauna, and well maintained hiking trails. The trail to the summit of Diamond Head is just 0.8 miles long, but it requires a strenuous rise from the crater’s saucer-shaped floor. Enduring hikers are rewarded with a spectacular view overlooking Oahu’s southern shore.
The park is open 365 days each year from 6 am to 6 pm. Entrance costs $5 for each vehicle or $1 for pedestrians. For more information, check out http://www.hawaiistateparks.org.
