1El Caminito Del Rey, Spain

Built in 1905, El Caminito del Rey was initially a path for workers to transport goods. Of course, the pathway is only three feet wide and dangles 330 feet up along the face of a cliff. When Spain’s King Alfonso XIII crossed the walkway in 1921, it earned the nickname “King’s Little Pathway.”

When the path fell into disrepair, officials closed it to the public for a decade. In many sections, only metal rails were left, but thrill-seekers still tried to walk the pathway and climb the mountain. Consequently, many people fell and perished. Following four years of improvements, El Caminito del Rey reopened in 2015.
