The Haʻikū Stairs, also known as the Stairway to Heaven, is a steep hiking trail 3,922 steps up the Koolau Pali to the 2800-foot summit of Puʻukeahiakahoe overlooking Haiku Valley on the island of Oʻahu. The trail began as a wooden ladder spiked to the cliff. It was installed in 1942 to enable antenna cables to be strung from one side of the cliffs above Haʻikū Valley to the other. A building to provide a continuous communication link between Wahiawā and Haʻikū Valley Naval Radio Stationwas constructed at the peak. The antennae transmitted very low frequency radio signals from a 200,000-watt Alexanderson alternator in the center of Haʻikū valley. The signals could reach US Navy submarines as far away as Tokyo Bay while the submarines were submerged. Testers for RCA picked up signals on Long Island, and the signal also reached India, 6,600 miles away. The station and trail were closed to the public in 1987. Hikers ignore the No Trespassing signs and continue to climb, contributing to the local community’s misgivings about reopening the structure.
Happy Aloha Friday!
