The hike up the Stairway to Heaven, also known as Haiku Stairs, is one of the most popular of Oahu’s "forbidden" trails. In the past, people used to climb up here for the fantastic panoramic views, which await all those who made it to the top. The hike is difficult. First you have to make the 2,120-foot, 3,922-step ascent. But even though the trail is closed today, some avid hikers go anyway because of the spectacular view that awaits from the top.The stairway was originally built for the U.S. Coast Guard to allow access to the LORAN radio antenna on the top of the mountain.
