4Haiku Stairs, Oahu, Hawaii

These stairs are actually so scary that they have been banned, as in no one is allowed to use them anymore.

This rickety set of 3,922 stairs leads half a mile up Oahu’s Koolau Mountain Range. These stairs were actually contrasted in 1942 by the U.S Navy as a means to install communication wires and were nicknamed the “Highway to Heaven”. Daredevil hikers quickly discovered them after WWII and started to climb them for their incredible views.
