I spent a day more in Aguas Calientes than planned. I actually wanted to go to Santa Teresa first, but I fell asleep during the trip and when I was in Hidroeléctrica, I just hiked right over the tracks to Aguas Calientes. There is a small thermal bath, which did my sore muscles very well. It wasn't very crowded, so I had my peace. In Santa Teresa there is also a thermal bath, which is larger, but I didn't like it so much.
