This fortress was built during the Venetian rule in the city. Even if the climb to it is not easy, it is nice to climb to the Venetian fortress on foot, through the stairs leading to the summit. The bonus for the effort is a pass through the ancient Teatro Romano, a Roman theater that is still used for performances and concerts.
You can also reach the Castelo San Pietro with the funicular, which gives a nice experience, especially for children.
You can enjoy the magnificent view from the fortress, and you can also enjoy the coffee shop and the restaurant next to it. In any case, Castel San Pietro will probably give you the most spectacular pictures of Verona and they will be right above, like a bird.
