The stairs began as a military necessity. In 1942, the U.S. Navy started building the Haiku Radio Station, a top-secret facility designed to transmit very low frequency signals to ships operating across the Pacific. Haiku Valley, a natural amphitheater carved into the Ko'olau Range, provided the geography the Navy needed: its steep walls could support enormous antenna cables stretched across the valley. To service those antennae, workers built a wooden ladder up the cliff face. The radio station was commissioned in 1943, powered by an Alexanderson alternator -- a massive device capable of generating the powerful signals that vacuum tube technology of the era could not. The original wooden rungs were eventually replaced with metal steps, and when the station closed, the stairs remained, clinging to the mountainside like a dare.

The station and trail were officially closed to the public in 1987, but closing a stairway to heaven is easier said than enforced. Hikers continued to slip past barriers in predawn darkness, drawn by sunrise photos that circulated first on postcards, then on Instagram. The stairs cut through a residential neighborhood in Haiku, and the neighbors bore the consequences: trespassers parking on lawns, leaving trash, making noise at four in the morning. In 2003, the city spent $875,000 repairing the stairs with plans to reopen them, but those plans stalled over liability concerns. By 2014, six people had been arrested and 135 cited in a single year for climbing. Criminal trespass in the second degree carried a $1,000 fine, but the fines did not deter. The stairs had become a bucket-list item, and the harder authorities made them to reach, the more determined the climbers became.

The debate over the stairs' fate dragged on for years. In 2020, Honolulu's Board of Water Supply -- which owned the land -- voted unanimously to transfer the stairs to the city, declaring them a liability incompatible with the agency's mission. The city took possession on July 1, 2020, briefly imagining a paid tourist attraction. But the math never worked. The entrance sat in a residential neighborhood with no room for parking, restrooms, or the kind of infrastructure a high-traffic trail demands. In September 2021, the Honolulu City Council unanimously passed Resolution 21-154 urging removal. Friends of Haiku Stairs, a volunteer advocacy group, proposed managing public access at no taxpayer cost, but Mayor Rick Blangiardi held firm. The removal cost ballooned from an estimated $1 million to nearly $2.6 million. Nakoa Companies won the contract, and crews began dismantling sections to be airlifted out by helicopter.

Even as the demolition proceeded, people tried to climb. Police issued citations to trespassers who entered the active construction zone. In late August and early September 2024, fourteen people were arrested, each facing misdemeanor charges carrying up to thirty days in jail. In June 2025, the nonprofit Friends of Haiku Stairs filed a lawsuit seeking to reverse the demolition decision. Whether any portion of the structure survives that legal challenge remains uncertain. What is certain is that the view from the ridge -- the sweep of Kaneohe Bay, the emerald corrugation of the Ko'olau cliffs, the clouds rolling through the saddle -- persists regardless of whether steel steps lead to it. The mountain does not need the stairs. It never did.
