Tuscany brings together art cities such as Florence, the vineyards of Chianti and the hills of the south, where nights stay cool for much of the year. The region also has its hot springs, from Bagno Vignoni to Saturnia, where the water comes out of the ground already lukewarm or hot. So there are two ways to swim in warm water here: the heated pool of a villa or castle, or a thermal pool. I've selected 30 places, all rated at least 8/10; the top-rated is Hotel Le Fontanelle (4.8/5).
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.
