HONOLULU | Diamond Head State Monument is one of Hawaii’s most recognised landmarks. Formed over 300,000 years ago as part of a single volcanic eruption, Diamond Head is known for its historic hiking trail, stunning coastal views, and military history.
The mountain is known as Lēʻahi in Hawaiian. The name Diamond Hill (which later became Diamond Hill), was given by British sailors, who mistook the mountain’s sand’s sparkling volcanic calcite crystals for diamonds.
The first United States military reservation on Hawaii, Fort Ruger, was located in Diamond Head, and some of the old military structures remain. Hiking to the summit along is easy to moderate, with a clearly defined path that’s 0.8 miles / 1.3km long, with a gain of 560ft / 171m.
When you reach the summit, you’re treated to some of the most spectacular views of Honolulu, across the Pacific Ocean, and surrounding mountains and valleys. Entrance is free for Hawaiian residents, and USD$5 for non-residents. Bookings can be made online for set entrance times, up to 30 days in advance.
