During your stay in Venice try to be Venice friendly. To believe in and to contribute to a sustainable tourism it is really important for us.
Take a guide
Visit Venice with a qualified local guide: in addition to to having been fully examined on her/his knowledge of the city, she/he will be able, as a local, to help you immerse yourself in city culture and to describe traditions, costumes, gastronomy and lifestyle of the Venetians. She/he will help you in being part of it all.
And now a few rules in order to enjoy Venice 100%
Inside churches one must dress in an appropriate way with shoulders covered and skirts or bermudas to the knees.
Inside St. Mark’s Basilica
Backpacks are not allowed and photos are prohibited in the Basilica. Furthermore it is forbidden to sit down and picnic anywhere in the whole square.
In the whole town your legs are the only mean of transport allowed (apart from public boats). Bicycles, motorbikes and cars are forbidden.
It is severely prohibited to feed pigeons (it is also a bad idea as they cause several diseases)
