The Caminito del Rey (King's Path) – so named because Alfonso XIII walked along it when he opened the Guadalhorce hydroelectric dam in 1921 – consists of a 2.9km boardwalk that hangs 100m above the Río Guadalhorce and snakes around the cliffs, affording breathtaking views at every turn. Required walks to/from the northern and southern access points make the total hiking distance 7.7km.
The caminito had fallen into severe disrepair by the late 1990s, and it became known as the most dangerous pathway in the world; it officially closed in 2000 (though some daredevils still attempted it). Following an extensive €5.5-million restoration, it reopened in March 2015 and is now safe and open to anyone with a reasonable head for heights.
The boardwalk is constructed with wooden slats; in some sections the old crumbling path can be spied just below. The walk can only be done in one direction (north–south), and it's highly advisable to book a timeslot online. Buses (€1.55, 20 minutes) leave on the half-hour from El Chorro train station to the starting point, where there's a couple of restaurants. From here you must walk 2.7km to the northern access point of the caminito, where you'll show your ticket and be given a mandatory helmet to wear. At the end of the caminito there's another 2.1km to walk from the southern access point back to El Chorro. Allow about four hours for the walk, as the views are made for savouring.
The most convenient public transport to the area is the train from Málaga, which leaves twice daily to El Chorro station (42 minutes, €4.85). If you're driving, you can park at either end and use the bus to make your connection.
