The Bolton Strid

The Bolton Strid is a picturesque stretch of river that resembles the kind of location where fairies might be seen playing in the heath. But a natural booby trap that has claimed a number of lives is lurking just below the surface. The Bolton Strid in Yorkshire, England doesn't appear particularly intimidating at first glance. It doesn't even seem like anything because it's simple to ignore it as a little, easily-crossable stream of water while out for a stroll in the English countryside. But if you attempt to cross it, it might be the last stream you ever cross without carefully inspecting what's inside.

In reality, the Bolton Strid is a huge river that has been flipped on its side. It is hard to escape once you enter the supposedly innocent brook's vast depths, which include extensive networks of enormous tunnels. According to local legend, the brook has had a 100% kill rate over the years, making it perhaps one of the most dangerous places in the world.
