Italy's grand tour route exists because it works — Rome's ruins, Florence's Renaissance art, and Venice's canals are each worth a trip on their own, and seeing all three in sequence shows how dramatically the country changes character every few hundred kilometres. This itinerary builds in proper time in each city rather than treating them as checkpoints.
Ideal for travelers who want history, art, and food in roughly equal measure, with a relaxed Tuscan countryside stop to slow things down.
