1. Tianmen Mountain Road, China
11 Km long and with an elevation change of 1100 m from start to finish, this Chinese roadway is not for the faint of heart. With 99 hairpin turns, this road isn’t narrow by the standard of other roads mentioned in this article, but meeting an oncoming vehicle can make things a bit challenging. There are barriers all along the route but too much speed or getting caught up in the beauty of the surrounding mountains won’t prevent you from going over the edge and taking a rather long fall to the bottom.
