    Haʻikū Stairs (aka “Hawai‘i’s Stairway to Heaven”) was built for the US Navy in 1942 in response to the attack on Pearl Harbor. The Stairs provided access to the summit of Puʻukeahiakahoe on the Koʻolau ridge and enabled construction of the antenna system that served the Naval Radio Station at Haʻikū. Antennae were strung 7200 feet between ridges across  Haʻikū Valley to support the 200 KW transmitter station that was built in the Valley. As a result, it was possible to transmit critically important, long range, very low frequency (VLF) radio messages to submarines and other ships in Tokyo Bay and the Indian Ocean. The original cedar wood stairs were replaced by metal stairs in 1955 and a major renovation of the Stairs was undertaken in 2002.There are 3,922 steps to the top of Haʻikū Stairs. Total length is approximately 4000 feet with an average angle of ascent of about 30°.Climbers are rewarded with awe-inspiring views of the windward and leeward coasts of O‘ahu. Climbing the Stairs also provides the opportunity to experience a variety of fascinating microclimates and a wide range of rare and endangered native Hawaiian plants.
