This is a Spanish location used in THE DESERTER. It’s known as El Torcal de Antequera, and you get to it on your way from Malaga to Cordoba, heading up the MA-2, A-7, A7075, then finding a route sign that takes you 11 miles off the main road at Villanueva de Cauche.
In fact, the first motorway rest station on the route has a huge tiled-wall depiction of the place, which is what prompted me to visit.
There’s a big car park at the visitor centre
Then you wander along a bit and there’s the view
It’s very overgrown, and I hate to think what’s lurking down there now
