El Caminito del Rey

"El Camino del Rey is the name of a very dangerous walkway that winds its way along the steep walls of a narrow gorge known as El Chorro. The path has fallen into serious disrepair and official access to the path was removed in 2000 after 3 tourists died trying to cross it." (read more)

Just in case you're wondering, these were two groups of climbers

that were crossing the path... in opposite directions.

And here are some videos of climbers crossing el caminito:
