El Caminito del Rey (The King's Little Path) is a walkway, pinned along the steep walls of a narrow gorge in El Chorro, near Ardales in the province of Málaga, Spain. The name derives from the original name of Camino del Rey (King's Pathway), abbreviated locally to el caminito. The walkway had fallen into disrepair and was partially closed for over a decade. After four years of extensive repairs and renovations, the walkway re-opened in 2015. It has been known in the past as the "world's most dangerous walkway" following five deaths in 1999 and 2000.

The walkway was built to provide workers at the hydroelectric power plants at Chorro Falls and Gaitanejo Falls with a means to cross between them, to provide for transport of materials, and to help facilitate inspection and maintenance of the channel. 

The construction began in 1901 and was finished in 1905. King Alfonso XIII crossed the walkway in 1921 for the inauguration of the dam Conde del Guadalhorce, and it became known by its present name.The walkway is 1 metre (3 ft) in width and rises over 100 metres (330 ft) above the river below.
