Start your day early in St. Mark's Square with a visit to the stunning St. Mark's Basilica. Marvel at the golden mosaics and ornate façade of this magnificent Byzantine cathedral. Afterward, head to the nearby Doge's Palace, the former home of the Doge of Venice and seat of the Venetian government. Explore the opulent rooms and learn about the palace's history and significance. End your day with a walk along the Riva degli Schiavoni, taking in the views of the lagoon and nearby islands.
On day two, immerse yourself in the art and culture of Venice. Start at the Gallerie dell'Accademia, home to some of the finest examples of Venetian art from the 14th to 18th centuries. Afterward, head to the Peggy Guggenheim Collection, a modern art museum located in a former palazzo overlooking the Grand Canal. Admire works by Picasso, Pollock, and other famous artists. End your day with a stroll along the picturesque streets of the Dorsoduro neighborhood, which is home to many galleries, shops, and restaurants.
On your final day, experience the culinary and visual delights of Venice. Start with a visit to the Rialto Market, where locals buy fresh produce and seafood. Sample some of the local delicacies, like fried calamari or grilled sardines. Afterward, take a vaporetto (water taxi) or gondola along the Grand Canal, the city's main waterway. Marvel at the beautiful palaces and churches lining the canal, including the famous Rialto Bridge. End your day back in St. Mark's Square, where you can enjoy a spritz (a classic Venetian cocktail) and watch the crowds and street performers.
If you have more time, consider visiting other islands in the lagoon, like Murano (famous for its glass-making) or Burano (known for its colorful houses). You can also take a day trip to nearby cities like Padua or Verona. If you have less time, prioritize the top sights like St. Mark's Basilica and the Doge's Palace, and skip some of the museums or markets. Remember that Venice can be crowded, especially during peak season, so plan accordingly and book tickets in advance if possible.
