Koko Head, also known as Koko Crater, is a prominent volcanic landmark located on Oahu's southeastern coast. The crater, part of the larger Koko Head Regional Park, is famous for its challenging hike up the Koko Crater Trail, often referred to as the "Koko Head Stairs." This steep trail follows an old military railway track, with over 1,000 steps leading to the summit. At the top, hikers are rewarded with breathtaking panoramic views of the island, including Hanauma Bay, Maunalua Bay, and the Pacific Ocean. Koko Head is a must-visit for adventure seekers and nature lovers.
