Natural spas and hot springs in Tuscany

  • Tuscany, Italy

  • Bucket List Experience

Last updated: 21 March, 2024

Tuscany is full of natural hot springs or terme, many of which date from Roman or even Etruscan times and whose waters, originating from deep within the earth’s crust and emerging at around 35°C-37°C, have long been known to have therapeutic properties.

Each spring has a different combination of minerals and gases, so different terme are said to be beneficial for different conditions. Carbon dioxide boosts the immune system, for example, and sulfur-rich water is believed to benefit muscular and arthritic pain.

Hotels, some with day spas, have been developed around many of these springs, and while some are fairly modest, others have turned into luxury spa resorts offering first-class accommodation and a myriad of treatments (both medicinal and cosmetic) to compliment the thermal waters.

Grotta Giusti Hotel

  • Monsummano, Tuscany, Italy

Looking down over a large outdoor pool, filled with thermal hot spring water


The unique feature of the Grotta Giusti spa and hotel in Monsummano Terme is its extraordinary prehistoric underground cave system. An hour spent sweating in the dripping grotta offers relief from rheumatic pain and does wonders for the skin. After your sweat, you will be sluiced down naked in a small cubicle with a strong jet of water.

Adult price: 240

When to do it

The Tuscans love to wallow, particularly in cooler weather, and many go to the terme just for the day at the weekend. So Saturdays and Sundays at spas that offer day passes can get very crowded. If you’re staying at one of the more exclusive spa hotels, this is likely to be less of a problem; there is usually an area that is off-limits to non-residents.

There is something wonderful about wallowing in 35°C plus water (especially in an outdoor pool) when it’s cold outside, so winter is high season in spa resorts. In summer, the Italians go to the beach.
