We will be traveling by train to Bologna in mid-October and plan to stop in Modena for a day on our way there. What are the highlights you recommend seeing or doing during a day in Modena. Also, is there a place convenient to the train station to check bags for a day?
Ferrari museum is a must see. Next to the train station.
RadicalStorage.com for luggage storage. We really liked the convenience. Download the app.
If you are into art and architecture, the Duomo and the Galleria Estense.
If you are coming for the basalmic vinegar, I would schedule a cellar/attic lunch tour. Otherwise, the options mentioned are good.
