Via ferrata is wrong. It's name is Thousand feet.
Well, I initially posted this looking for Plank Path as the answer, which is the most common name for this path. A bit more research told me that it is also known as the Thousand-feet Precipice, according to which your answer is kind of incomplete, because the word precipice describes the path, BUT, I also saw that this picture.is saved on Wikimedia as Thousand Feet. Since the answers are based solely on research done by you, all will be the correct answer, congrats Joana.
The Plank path, also known as the thousand Feet Precipice, is deemed as the most dangerous mountain walks in the world. It is made solely of planks, which make a thin path, with chains to hold on to. It also has parts to climb. It has nothing to save you if you fall down.
Thousands of tourists from all over the world make this thrilling journey, just to end up at a tea shop, at the peak. Of course, the great view also accompanies them.
Just for your information, a Via Ferrata is an iron path.
Challenge goes over to you!
