Countless pages of glossy magazines and breathless travelogues have been devoted to Tuscany, and with good reason: This section of central Italy remains one of the loveliest places on the planet. Especially for those interested in wine, this itinerary encompasses the best this region has to offer: the Renaissance glories of Florence, the storied hill towns of Tuscany and the unspoiled countryside of Maremma. Just as important, it affords insider access to top wineries.
