On the island of O'ahu, there is a stairway that actually seems to lead to heaven. You have to climb 3,922 metal steps on the so-called Stairway to Heaven to reach the summit in the Koolau Mountains. The problem is that climbing the stairs is officially forbidden. The climb, which takes around five hours, has always been considered risky, but since 2015 it has become downright precarious. At that time, a storm damaged the staircase, which was already damaged. As early as 1987, the climb was banned. In 2005, renovations were made to the steps, which were built by the U.S. Navy in World War 2 and led to a secret radio tower. Security guards patrol regularly, as the ban is disregarded by many tourists. Those caught face a fine of up to $600 USD. The Friends of Haiku Stairs group has long had plans to extensively renovate the staircase.
