Hawaii – Haiku Stairs, also known as the ‘stairway to heaven’ – It is a steep hiking trail on the island of Oahu. The trail starts as a wooden staircase leading to the cliff on the south side of the Valley of Haiku. The staircase was installed in 1942 to stretch a cable from one side of the hill to the other side. This was necessary in order to provide a continuous link to the naval station during the war. In 2003, the staircase was restored at a cost of $875,000. Due to current legal issues of land use, the city and county of Honolulu said there is no current plan to open the stairs for public use.
