It's true that Venice not only seems to be sinking under its own weight in the sands of its lagoon, but also under the weight of the overflow of tourists it welcomes, day after day... But there is a remedy for that, if you don't like crowds: it's the quartier of Cannaregio.
Far from the pomp and bustle of St Mark's Square, Cannaregio is not in the centre of Venice: this _sestiere _(district) occupies the entire north-eastern part of the city. This sprawling district is not a must-see in the strict sense of the word, but rather a place to stroll, get lost and enjoy the atmosphere of a more authentic Venice.
Cannaregio itself has many facets, from the tall buildings of its former Jewish Ghetto to the bustling shops of its main shopping street, the Strada Nova: an exciting district, where you'll be happy to find a hotel!
