"HIGH WATER"

Generally Venice only has high water in Autumn and Winter and even then it is not every day that the streets are flooded. However when a higher than usual tide is expected in the city, sirens blare to warn the population so that they can prepar themselves. Maps as posted at the boat stops showing alternative pedestian routes around the city that are equipped with special footbridges to avoid the high water and to reach the main parts of Venice.
For further information call the Venetian Tides Service.
