You visit caves that were used in primeval times for burial rituals and for cult purposes. An archaeological educational trail was also created. Part of a Bronze Age village has been reconstructed, with life-size huts and areas for craft activities. The two sectors are connected by a route in the woods and along the rocky outcrop above the Belverde Caves, from where you can enjoy a wide panorama of the Valdichiana. A room for simulating archaeological excavations has been set up in a special area.

Great small thermal pools with 40 degrees hot water invite you to linger. Don't forget your bathing suit. Be careful not to stay too long in the pool when it's hot, as you could get circulatory problems. So drink a lot too!
