There were only few lights in the cave, and due to the water, the ambiance and the light were unbelievable. I remember I asked the group I was with to let me alone at the end, to shoot this. Even the silence was impressive.

Love this one too !

I made a quick research, actually this place is called Baths of Doña María de Padilla (Baños de Doña María de Padilla). They are actually former rainwater collection cisterns located beneath the Patio del Crucero.

I may change the name of my post now 🙃

I also sonder. I was in a big group of colleagues. It's possible to private for one hour.

I just had a look at it on their website. We were almost 30 people. For two guides it seems to be 360€. 12€/person. It's cheap for such an experience.
