El Caminito del Rey ("The King's Little Path") is a 1-meter-wide walkway pinned to the vertical limestone walls of the Guadalhorce Gorge near Ardales, Málaga, Spain. It hangs 100 m (328 ft) above the river.
Built 1901–1905 by the Chorro Hydroelectric Company to allow workers to commute between the Salto del Chorro and Salto del Gaitanejo power stations. King Alfonso XIII crossed it in 1921 for the inauguration of the Guadalhorce Dam—hence the name.
By the 1990s, concrete had crumbled, rails rusted, sections collapsed. Five deaths (1999–2000) forced its closure in 2001.
A €5.5M reconstruction replaced the path with steel beams anchored into the rock, wooden board decking, glass-floor sections, and continuous cable railings. It meets modern safety standards but retains the vertigo-inducing exposure.
El Caminito del Rey is now a world-class via ferrata-lite experience—thrilling, safe, and a testament to industrial heritage reborn as tourism.
