Located where the Clay Hills of Siena meet the Orcia Valley, San Giovanni is a centre for truffle-hunting: if you love truffles, you must visit for the truffle festival. The calendar is published at https://www.tartufodisangiovannidasso.it/

In San Giovanni d’Asso you can also visit the Bosco della Ragnaia, a wooded park and garden created in 1996 by American artist Sheppard Craig, who still maintains it: an enigmatic wood that can be interpreted a thousand different ways. More information at http://www.laragnaia.com/EN/
