El Caminito del Rey
Translated as "the King’s Little Pathway," this cliffy route near Málaga has been closed for years. But it remains one of the world’s most famous dangerous paths. Built into the cliffs above a narrow river gorge in the district of Málaga, the El Caminito del Rey path was originally for hydroelectric power plant workers. It has three-foot-wide walkways hundreds of feet off the ground. Concrete sections have collapsed, leaving steel beams and rotting ledges exposed. Old cables bolted to the cliff provide some grip as trespassing hikers make their way along the route.
