I spent a week staying on the Lido over a decade ago. This is where many of the locals live and you will find department stores and supermarkets here, even a movie theatre. Quite different to the sestieri of Venice.
The Lido is Venice’s barrier island, forming the southern border of the Venetian Lagoon and protecting Venice from the waters of the Adriatic. It forms the beach of Venice, and is home to a series of bathing establishments, both public and private, covering the sand with row upon row of beach chairs. Some are luxurious and elegant extensions of expensive hotels and others quite simple, catering to Venetian families and their children. When the sun is shining the Lido beach is full of people of all shapes and sizes tanning their skin with Italian confidence and style - unforgettable.
The other attractions here are more architectural and include modernist villas dating from the early 1900s and also several art nouveau hotels, as well as Venice's Jewish cemetery.
