Caminito del Rey

El Caminito del Rey (English: The King's pathway) is a walkway or via ferrata, now fallen into disrepair, pinned along the steep walls of a narrow gorge in El Chorro, near Álora in Málaga, Spain. The name is often shortened to El Camino del Rey.

History

In 1901 it was obvious that the workers of the Chorro Falls and Gaitanejo Falls needed a walkway to cross between the falls, to provide transport of materials, vigilance and maintenance of the channel. Construction of the walkway took four years; it was finished in 1905.

In 1921 the king Alfonso XIII crossed the walkway for the inauguration of the dam Conde del Guadalhorce and it became known by its present name.

In some places the walkway has collapsed

The walkway has now gone many years without maintenance, and is in a highly deteriorated and dangerous state. It is one meter (3 feet) 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 the path. One can latch onto the wire to keep from falling. Many 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 into the walkway.

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