Terme Grotta Giusti in Monsummano

Nestled in the hills of Valdinievole, Monsummano Terme holds a true natural spa paradise that is Grotta Giusti.

First referred to by Maestro Giuseppe Verdi as the “8ᵗʰ wonder of the world,” the millennia-old cave stretches more than 656 feet (200 meters) underground, creating subterranean labyrinths adorned with stalactites and stalagmites along with spacious caverns that evoke the Dantean atmospheres of Hell, Purgatory and Paradise.
 
At the base of the cavity lies a crystal-clear mirror of hot thermal waters at a temperature of around 97 °F (36 °C), emitting a healthful and therapeutic steam that envelops guests in a beneficial and detoxifying “sauna.” Temperatures here experience very limited seasonal variations, going from 82 °F (28 °C) to 93 °F (34 °C).

Diving enthusiasts can plunge into a thermal cave under the guidance of experienced instructors.

Located within the century-old park of the 19ᵗʰ-century villa of poet Giuseppe Giusti’s family, today the Grotta houses a resort and spa with an outdoor swimming pool where the thermal waters reach 95 °F (35 °C), equipped with the highest level of technology, with an 8072-square-feet (750-square-meter) mirror of water, a scenic waterfall and 40 whirlpool spots.

Grotta Giusti is a unique and rejuvenating experience for the mind and body, just a few miles from the major art cities of Tuscany.
