We are planning to spend 5 days in Florence/Siena region during Easter March 28 - April 1. The plan so far is -
day 1 - Take train to Florence, siteseeing
day 2 - full day bike tour to Chianti region
day 3 - siteseeing in Florence, take train to Siena
day 4 - undecided
day 5 - siteseeing in Siena and train back to Zurich.
We are looking for some suggestions for things to do on day 4 from Siena - cycling or walking day tour or siteseeing by bus. We prefer not to drive unless there are not-to-miss sites we cannot do without car. We have already been to Florence once, and cinque terre etc, so do not want to spend time in that region.
