that was "El Caminito del Rey" in Spain. Wiki it. It was built when workers needed to move supplies for a hydro-electric facility at the falls...but wasn't maintained and fell into disrepair. It's blocked off, but (obviously) people can climb around barricades and hike it...EEEEEUUUSH!!!! LOL There is even a Flash game called Chasm (?) that is kinda addictive...based on this pathway.Cool Video. Where was it filmed? I would hike that just for the experience. Just once though. There are times when I am about as graceful as three legged drunken cat. That little balancing beam act at the end would likley dispell the rumors about my abilites to fly.
