At the Embalse de Yesa, a lake in the province of Aragón in Spain, you will find the hot springs of Tiermas. It is a wonderful experience to lie in the slowly flowing water that has a temperature of around 35 degrees Celsius. There is a strong sulphur smell but you get used to that quickly. Many people rub themselves with the mud. That is supposed to be healthy and in combination with the environment results in rather special pictures.
