The territory of San Giovanni d’Asso, reachable in 10 minutes by car from San Quirico d’Orcia, covers the central-southern area of the Crete Senesi, reaching the northern border of the Val d’Orcia. Here it is possible to visit the first Italian museum dedicated to the Truffle, of maximum naturalistic interest, is the Bosco della Ragnaia, a wood-garden that covers about 9 hectares, and is the work of the artist Sheppard Craige who, since 1996, continues to expand it and beautify it.
