I watched this video to the end and the sensation is hard to describe. I felt a weird sensation in my lower back and it seemed close to a mild panic. The technical term is called "acrophobia".
The El Caminito del Rey is a narrow pathway constructed between 1901 to 1905 in Spain. It rests on steel pins embedded into the walls of a cliff face in El Chorro, Spain. The pathway started crumbling and after some deaths, was closed and a newer safer pathway constructed.
This walkway is often referred to as the scariest hike in the world and is still frequented by adventurous tourists every year.

As the walk progresses higher, the crumbling areas become more frequent and in some cases the concrete has disappeared completely.
