Caminito del Rey

This Spanish walkway (sometimes shortened to Camino del Rey – “the King's Trail” in English) is a path that clings to the side of a gorge in the southern Spanish province of Malaga. Over the years, sections have eroded away, and sometimes hikers find themselves confronted with the choice of turning back or crossing narrow ledges or steal beams that once supported the now-completely eroded path. Guided tours are the best option for this trek because they can provide added security features — including safety lines, which are attached to the rock wall above the pathway so hikers can hook on during the journey. Even with the extra safety measures, Caminito del Rey is still an extreme hike that is truly one of the classics of Europe.
