How about discovering Tours like a real local? Let your guide walk you through and he will show you the essentials of course but also the little details that no one notices.
While walking you will have all the opportunity to see the people of Touraine live, in particular by passing in front of the Saint-Gatien Cathedral (built in the 12th century), the rue Colbert (or "the street of the restaurants") or the Place Plumereau (elected most beautiful place in France to have an aperitif).
A gourmet stop will allow you to taste Touraine specialties (cheeses, charcuterie, wines, etc.).
A morning you won't soon forget!
