Exit A1 Chiusi-Chianciano Terme, you turn left following the signs for Sarteano.

After about 6 Km you arrive in the main square of the village and you take Viale Amiata (on the left) following the signs for "Radicofani."

After about 7 Km you will see on your left a, rough dirt track "Fontevetriana," follow it for about 1 Km then turn left and go on for 50 m. you will be in the small square of this characteristic hamlet.

Have a good journej!!!
