1. STAIRWAY TO HEAVEN
The Stairway to Heaven also known as the Haiku Stairs on Oahu, Hawaii, is possibly the greatest attraction on the entire island. 3,922 stairs lead up the imposing mountain ridge, often at a vertical incline, with only a hand-rail to catch you from falling into the valley below.
Originally the stairs were built in 1942 by the U.S. Navy as a top secret facility for transmitting radio signals to ships that were sailing in the Pacific Ocean. The stairs were then opened to the public until 1987 when they were deemed unsafe because of disrepair. This is probably the most famous of all the hikes on Oahu and has been covered by most newspaper outlets.
