While a single day is not enough to explore Venice fully, It is a popular day trip from Milan as it takes only about 2-2.5 hours by high-speed trains like Frecciarossa or Italo. It is unlike any other city in the world, with its canals, historic palaces, and iconic landmarks such as St. Mark’s Basilica and the Doge’s Palace. Reserve train tickets, gondola rides, or guided tours in advance to save time.
