A lovely sunny day in Verona:
Start your day with a cup of cappuccino:
If you are coming from the train station probably the first thing you are going to see is the Arena:
It will be hard to miss the house of Juliet. Even if it's normally very crowded it's worth visiting it.
Enjoy the lovely view from The Lamberti Tower, It's the best way to see all the city from above.
Don't try to see everything, it's hardly possible. Instead leave something for the next time, so there will be a reason to come back again :)
