3 Best Sights in Tuscany, Italy

Here you'll find two natural steam-room caves, as well as spa services such as mud baths, massage, hydrotherapy, and facials.

This spa has two buildings with a large park in the middle and three types of water: Acqua Santa, Acqua Fucoli, and Acqua Sillene. Mud baths happen at the last, and the website lists the other varied spa treatments that are available. The all-important mineral water is served at long counters, where the spa staff is always ready to refill your glass. Be warned: The water can have a cleansing effect on your system that may come on suddenly.

The swimming pools and treatments at Terme di Saturnia spa and resort are open to the public. You might make an appointment for a thermal mud therapy or rent a lounge chair and umbrella to sit by the pools. On weekends, the day price jumps a wee bit.
