Aguas Calientes (literally "hot waters") takes its name from these thermal springs that sit above town. Don't expect Baden-Baden, but if you aren't too fussy, this can be a refreshing dip at the end of a hot day, where you can sip a pisco sour while you lounge. Towels and even bathing suits are available for rental just outside the baths.
