Yosemite Valley’s signature hike is Mist Trail, despite it being the most treacherous hike in the world. Even though it’s only 1.5-miles, many trekkers have died trying to get to the top of Vernal Falls. At the top is a barrier preventing trekkers from continuing any further, but many people choose not to listen to the warning and end up plummeting to their death. Not only that, but many other parts of the lower trail are also dangerous, and the river is prone to flooding. Additionally, even though 15 deaths out of 4.3 million visitors per year doesn’t sound like a lot, all of the deaths were preventable(Adventure Sports Journal).
