Italy
Hot sulphur springs cascading over travertine terraces into pools the water itself carved.
Warm sulphur water slides over white travertine shelves into pools that glow pale against the dark Maremma night. Steam curls off the surface in slow columns with a faint mineral bite. This is bathing as it existed before the Romans arrived, shaped by the mineral flow alone.
The Cascate del Mulino at Saturnia are fed by a spring that arrives at about 37 degrees all year, spilling terrace to terrace over travertine the water itself laid down. Bathers have come since Etruscan days, and the falls remain wild ground, unfenced and unbuilt. A separate spa resort above the falls sells the managed version. Around it all rolls the emptier Maremma, low hills, olive rows and stone farmhouses that see a fraction of central Tuscany's traffic.

Steam rising off the terraces, the Maremma's quiet all round and a farmhouse bed nearby make a weekend feel longer than it is.
Friends
The terraces are big enough to claim a basin each, with a boar feast and Morellino waiting up the road.
Family
Warm mineral water spilling terrace to terrace, over travertine that stays slippery underfoot.
Acquacotta with an egg cracked into it turns the Maremma's field lunch into proper comfort.
Morellino di Scansano, the local red, pairs with slow-cooked boar in farmhouse trattorias.
