Bormio is the site of a natural hot spring and has three spa/baths. The weather today was truly awful so we headed for the Bagni Nuovi.
It was brilliant. The first level contained several saunas, steam rooms, plunge pools and hydrotherapy pools. Then there was the grotto area that had a number of interesting treatments, like a pair of elliptical pools that you walked through, one containing warm water, one cold. Its supposed to be good for your circulation and certainly made our tired legs feel better. There was also a big outdoor area with mud baths, hot tubs, more saunas, a swimming pool and much more. My particular favourite was a eucalyptus shower followed by a sauna in a converted summer house, though the windows of which you could watch restarts and other birds.
We managed to spend 6 or 7 hours there.
