Built in 1901, and currently in considerable disrepair, this walkway, called El Caminito del Rey, serves as an entrance to Makinodromo, the famous climbing sector of El Chorro in Spanish Andalusia.

The walkway has now gone many years without maintenance, and is in a highly deteriorated and dangerous state. It is one meter (3 feet and 3 inches) in width, and is over 200 meters (700 feet) above the river. Nearly all of the path has no handrail. Some parts of the concrete walkway have completely collapsed and all that is remaining is the steel beam originally in place to hold it up and the wire that follows most of the path. One can latch onto a safety-wire to keep from falling. Several people have lost their lives on the walkway in recent years; after four people died in two accidents in 1999 and 2000, the local government closed the entrances. However, adventurous tourists still find their way onto the walkway to explore it.

The regional government of Andalusia budgeted in 2006 for a restoration plan estimated at € 7 million.
