Day 2: The Walls and the Castle

Morning: Walk around the Venetian Walls, a UNESCO World Heritage Site. They're a suspended park offering stunning views of the lower city and the plain, especially on clear days. It's one of the most romantic walks in northern Italy.
Lunch: Try the famous Polenta Taragna (polenta with melted local cheeses), perhaps accompanied by braised meat or mushrooms.
Afternoon: Take the second funicular (San Vigilio) to ascend even higher to the Castle of San Vigilio. Here you're at the highest point in the city: explore the ruins of the fortress and enjoy the tranquility and breathtaking view.
