Its in all the guidebooks and on the interweb.
I find that after lots of exercise then a sauna and spa are just the job. Say after 60km of riding and a challenging hike.
The spa is, unfortunately, the most run down that I have seen or been to since being in Asia... half the spas are unfilled, paint
is peeling off the walls, and generally the place shows serious neglect.
All bathed and clean and after a reasonable meal (the only customer), It was time to find somewhere to pitch the tent...
