Harihar Fort in india is a hiking trail known for its 80 degree vertical rock stairs. It is built on a triangular prism of rock at a 80 degree vertically inclined angle located in the Trimbakeshwar Mountain Range. The Yadava Dynasty constructed the fort between the 9th and 14th centuries and has held great importance in preventing trade routes passed through the Gonda Ghat. Harihar Fort was repeatedly attacked and seized by many invaders before the British Army took control of it. Like history?
