We will be staying in Siena for three nights amd want a tour that goes to wineries amd is possible a hill town. All the tour options seem to be private amd more than 125 euro per person! We would like to spend half of that and dont mind a shared tour. Any other options ( without a car simce we want to drink)? Are there wineries we can take the bus to? Anyone know of an expensive, good tour? Thanks!
