Diamond Head Mountain is one of the most popular outdoor attractions on Oahu. It is the most popular hiking trail for young people. The difficulty factor is moderate. Basically, the elderly and children can also climb it. After reaching the top, you can overlook Honolulu and enjoy the beauty of Waikiki Beach. Tickets cost one dollar per person, and the price/performance ratio is quite high.
Diamond Head is worth a visit. An easy walk up you will be rewarded with great views of the ocean and towards Waikiki.
We enjoyed hiking to the top. We love the view. We went there early in the morning to avoid the heat of the sun.
