Terme libere in Italia: cascate calde e sorgenti termali gratis
L'Italia ha una geografia termale unica: dalle famose Saturnia alle meno note Bagni di Petriolo (Toscana), Bagno Vignoni (Val d'Orcia), San Casciano dei Bagni, Bullicame di Viterbo (dove Dante incontrò l'acqua bollente dell'Inferno). Molte sono libere e gratuite, aperte 24/7, e più belle fuori stagione — quando i vapori si condensano contro il freddo. In questa guida completa raccogliamo le terme libere italiane raccontate.

Quando andare
Alba (per Saturnia soprattutto) e mesi freddi (novembre-marzo) — quando i vapori sono più visibili e c'è meno gente.
Cosa portare
Costume, ciabatte di gomma (fondo scivoloso), asciugamano grande, borraccia. In alcune terme (es. Bullicame) l'acqua è molto calda: non trattenerti a lungo.
Rispetto
Le terme libere non hanno personale: raccogli sempre i tuoi rifiuti, non usare sapone/shampoo (inquina falde), non spostare le pietre delle vasche.
Salute
Se soffri di problemi cardiovascolari, consulta il medico. Non entrare a stomaco pieno o dopo alcol. Idratarti prima e dopo.
