3El Caminito Del Rey, Spain

(The Royal Trail) is much more commonly referred to as the trail of death. It is indeed among the most extreme mountain trails in the world. The tracking is located in one of the most visited climbing areas in Europe, the El Chorro Gorge, which is located in the Spanish province of Malaga (Andalusia).
Over time, the road was no longer used, and it began to deteriorate slowly. But when the fashion for extreme tourism came, El Caminito del Rey was remembered again. After a series of accidents on the “trail of death,” the authorities banned the route in 2001.
