The Haiku Stairs gained strategic importance during World War II. The U.S. military recognized the value of the ridge as a vantage point for transmitting radio signals. A wooden ladder was constructed, followed by a more durable metal staircase to facilitate easier access to the radio station at the summit. The antenna installed at the top was crucial for communicating with naval fleets operating throughout the Pacific.

These remarkable stairs were constructed in the Haiku Valley between 1942 and 1943, serving as a clandestine passage to a secret naval radio station. A duo by the names of Bill Adams and Louis Otto meticulously mapped out this challenging ascent, leaving behind invaluable spikes to aid future climbers. Initially made up of ladders, these were later replaced with sturdy wooden and galvanized steel steps, some of which still endure today.

Each section of these stairs measures 6 feet in length, boasting 8 steps and handrails on both sides. Securely fastened with metal pins, they carry an average slope of 30º, ensuring a thrilling adventure for those brave enough to ascend. Unfortunately, in February 2015, a devastating landslide rendered the staircase inaccessible and forbidden to climb. However, there exists an alternative route through the Moanalua Valley Middle Ridge Trail for those seeking a safe passage to the summit.

The Haiku Stairs are a steep, rugged series of galvanized-steel ship ladders. Beginning at the valley floor, they gradually ascend over 2,500 feet through lush, tropical vegetation and misty cloud forests. Each of the roughly 3,922 steps, stationed approximately 12 inches apart, is reinforced by a central metal railing, providing vital support on this vertical escapade. The stairs wind up the rugged Koolau mountain range, often leaving climbers feeling as if they’re on a Stairmaster in the sky. By the time you reach the top, you’ve traversed a staircase that spans a distance equivalent to more than a quarter of Mount Everest’s height.

Please note: Haiku Stairs is a formerly private property, you’ll be trespassing upon setting foot on these legendary stairs. Beware of the consequences, as hiking or stepping on the stairs can result in a hefty $1000 fine. With guards patrolling the bottom and police helicopters surveilling the area, the stakes are high.

The legal path to reach new heights is by taking the Moanalua Middle Ridge Trail to the iconic Haiku Stairs. This exhilarating 9-mile trail is perfect for experienced hikers looking for a challenge.

Begin your adventure at the Moanalua Valley Road trail and at around 2.5 miles, veer left to enter the valley. You can easily access this valley by taking Exit 19B off the H1. Simply follow the signs up Moanalua Valley on Ala Aolani St. until you reach the end of the road at the Community Park. Park outside the Moanalua Valley Park to find the trailhead, conveniently located just after the green gate.

As you embark on the hike, keep an eye out for the Kulana’ahane trail sign. However, remember not to follow this particular trail. Walk an additional 15 feet and you’ll spot a small, unmarked trail on your left. Despite its size and lack of signage, this trail is unmistakable and will lead you to the radio tower and the top of the ridge.

Accessing the viewpoint at the top doesn’t require using the stairs. However, for a bonus experience, you can still take a leisurely stroll down the stairs for some fantastic photo opportunities before returning to the designated trail. To streamline your journey, consider parking a car at both ends of this route.
