El Caminito del Rey, or the King’s Little Pathway, is a narrow walkway set against the walls of a deep gorge that’s been called “the most dangerous path in the world.” Originally constructed in the early 1900s as a route for hydroelectric power plant workers, the meager trail fell into severe disrepair over the course of the century. By the year 2000, following four fatalities in the previous year, the pathway was closed to the public and was under construction for more than a decade.
