As magnificent as Venice is, there are a lot of options, if you would like to take a day trip away from La Serenissima. First of all, there are all the islands in the lagoon. many of them are visitable with a tour company or even with Vaporetto. Murano, Burano, Torcello, etc. is very easily accessible with a simple water bus ticket.
Many of the other islands can be visited but require a bit of planning. You might have to use a private company, or the public transport only goes there a few times a day, or even a few times a week.
And lastly, there is a world to discover inland. Italy is a very rich country when it comes to cultural heritage. No country in the world has as many as many sites on the UN world heritage list as Italy. And if you have more than just a few days in Venice, it could be a very good idea to check out some of the other cities, or towns nearby. Or you might use a different strategy. Avoid the crowds in Venice, stay in one of the alternatives to the overheated touristic metropolis, and just come in for the day.
Many stay at Cavallino in summer and combine Venice with a few days at the Adriatic Sea to work on the tan. Others chose Lido di Venezia for the same reason, or Chioggia, which has many of Venice’s features but at a lower cost and with fewer tourists.
This section is about everything that surrounds Venice, in the lagoon, towards the Adriatic Sea or inland.
