Haiku Stairs

It provided pedestrian access to former U.S. Navy communication facilities on the island of Oʻahu, Hawaii[1] with more than 3,000 steps along O‘ahu's Ko'olau mountain range.

To transmit such a powerful signal, the Navy needed a transmitter of greater capability than possible with vacuum tube technology at the time.

They therefore decided upon an Alexanderson alternator, a huge device capable of generating powerful low-frequency radio signals, and requiring a large antenna.

[7][8] In early 2018, the City and County of Honolulu stated that there was no plan to open the stairs for public use, citing liability concerns.

[13] Friends of Haiku Stairs, a volunteer group aimed at preserving the trail, objected to the decision, saying they have a plan managing safe public access and trespassing at no taxpayer cost.

[14] The mayor said that removal will proceed as a high-use tourist attraction is inappropriate with an entrance through a residential neighborhood that lacks the room for necessary facilities such as parking.

[18] As crews began the dismantling process to prepare the stair sections to be flown out by helicopter, the police gave out citations to people attempting to ascend the trail by entering a construction area.

[19] In August 2012, Don Tiki show singer and comedian Fritz Hasenpusch died of a heart attack during his Haʻikū Stair climb.
