This is a bit tough to watch -- especially for those who are afraid of heights:

Unbelievably, the Caminito del Rey is a real path in Spain and many people have died trying to walk it:

The walkway has now gone many years without maintenance, and is in a highly deteriorated and dangerous state. It is one meter in width, and has over a 700 meter fall. Nearly all of the path has no handrail. Some parts of the walkway have completely collapsed and have been replaced by a beam and a metallic wire on the wall. 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.
