The King’s Route is an unique walkway in Spain but not someone to attempt if you are scared of levels.

It is 3km (1. 9 miles) long, 100 metre distances (328 feet) high and just a single metre wide.

The King’s Path (El Caminito del Rey) in Malaga has been closed in 2001 for protection reasons but re-opened in 2015 after a massive restoration project. Brand new fencing keeps walkers safe because they cross a narrow gorge using a sheer drop to the river beneath.
