As described in most comments drive to "Campillo de Arenas" first, already from the roundabout at the start of the cities there are signs and Google from there tells the same way. The road from the village takes around 10 min, at times is very steep, narrow and windy. It's paved with gravel on top. Suitable for VW Multivan but rather not for very large RVs. The place itself is peaceful & stunning
