There is quite a good exhibition running in the village of El Chorro covering the history of the Caminito del Rey, El Chorro and Guadalhorce reservoir constructions
The exhibition is located in “La Garganta” hotel and restaurant complex in the village of El Chorro, just 50 metres from the train station.
There is a large collection of old tools and implements and quite a few information boards detailing the various engineering projects in the area including the famous train line and tunnels that were used for the filming of Von Ryans Express. The only issue is that all the info boards are in Spanish language.
It’s well worth a visit as the hotel restaurant is also open to the general public and serves fine traditional foods at very reasonable prices. All in all a great and fascinating way to while away an afternoon.
