The hermitage is in a very cool place, with water falling from the top of the mountain. Inside, the two limestone formations from the flow of water make it very interesting. The walk from there to the gorgas is short and the gorgas area is spectacular. There is a nativity scene and the first thing you ask about is how they got it there. Going to the end of the gorge, where the water comes out, is beautiful. The light contrasts allow for spectacular photos.

It is dangerous to drink the water from the ravine or from the gorgas since it passes through a modification zone, the one from the hermitage is good.
