The Koko Crater Railway Trail, often referred to as the Koko Head Stairs, is a popular and challenging hike located in the Koko Head District Park in Honolulu, O‘ahu. This steep ascent takes you up approximately 1,048 steps along an old railway track, originally used during World War II to transport supplies to a military lookout post atop the crater. The hike spans about 1.6 miles round trip and offers an elevation gain of roughly 912 feet, making it a strenuous climb. The steep incline and exposed sections can be demanding, especially when hiking under the hot sun.

As you make your way up the stairs, the hike rewards you with stunning views of the southeastern coastline. Once at the summit, you’re treated to panoramic 360-degree vistas, including breathtaking views of Hanauma Bay, the Hawaii Kai area, and, on clear days, parts of Moloka‘i. These views make the effort of the climb well worth it, as you’ll feel a sense of accomplishment upon reaching the top.

The trailhead is located at Koko Head District Park, where parking is available, though it can fill up quickly, especially on weekends. Be sure to arrive early to secure a spot. While restrooms are available at the park entrance, there are no facilities along the trail, so be sure to bring water, snacks, and sun protection. The trail is exposed, with little shade, so be cautious of the heat, particularly during midday. Sturdy footwear is essential due to the uneven steps and occasional slippery sections. Whether you’re looking for a physical challenge or simply want to enjoy some of the best views O‘ahu has to offer, the Koko Crater Railway Trail is an unforgettable experience.
