A good soak in a naturally heated pool is always alluring. The area around Los Azufres is well known. But what about the balnearios of the north shore of Lago Cuitzeo, as at or near Huandacareo? Are they true hot springs, and how much is dedicated to kiddie water parks, with slides and kids on every side? (Something we prefer to avoid.)
Late last year, a poster on the Lonely Planet Thorn Tree, Mexico Branch, told me about her pleasant experiences swimming at a balneario at Araró. We wanted to check it out, but regional security conditions were "heating up", and as the weather grew colder, and we put this trip aside. I believe the principle balneario is called "Los Hervideros". http://www.balnearioloshervideros.com/
Anyone here with personal knowledge of that place or others in the Zinapecuaro-Araró area?
