Le Terme – The Hot Springs of Tuscany
L'Antica Querciolaia is one of the Hot Springs of Tuscany near Siena. You'll need a car to get there from Florence but it is a whole day out with sun and relaxation. Entry was €14 and there are treatments such as massages available in addition. To get the best sunbeds in Summer, you'll need to arrive quite early (before 11am) and there are umbrellas for those (like me) that can't manage a full day under the Tuscan sun.
