The Haʻikū Stairs, also known as the Stairway to Heaven or Haʻikū Ladder, is a steep hiking trail on the island of Oʻahu, Hawaii. The total 3,922 steps span along Oahu’s Ko’olau mountain range. Access is forbidden by the Hawaiian government due to liability issues and land access problems.
“Haiku” does not refer to the Japanese poetry genre. The area is named “Haʻikū” after the Kahili flower. Originally built to transmit radio signals to Navy ships that were operating throughout the Pacific during World War II. In order to obtain the necessary height for the antennae, the Navy stretched them across Haʻikū Valley, a natural amphitheater surrounded by high ridges. To accomplish this, they needed “easy” access to the top of the ridges, so they installed a wooden ladder up the mountain. The ladder was later replaced by a wooden staircase. The trail was closed to the public in 1987. Some hikers ignored the “no trespassing” signs and continued to climb, contributing to the local community’s misgivings about reopening the structure.
