This mountain hike includes scaling the side of the cliff to reach the peak, but it’s definitely not for those afraid of heights. Patrick Watkins from Malaysia hiked Mount Hua Shan in China, known as one of the scariest hikes in the world. Sections of the hike include attaching oneself to a rope around the mountain and scaling the mountain on a very narrow plank. Without a barrier on the side, the only thing preventing a fall is the one rope and a steady balance.
