Venice is said to have some 150 canals, and on top of that a lot of canals were interred in the 19th century for various reasons.
I was recently asked if I had paddled all the canals of Venice, and I haven’t. There are parts of Venice with unpleasant traffic or just run down places where you don’t go unless you have to, and even if I have been to many of those places too, there’s still a handful of canals I haven’t paddled through yet.
To get an idea of how much of Venice I’ve paddled I’ve marked in light red the waterways where I haven’t been, on this map.
Maybe half the unexplored canals are dead ends where you’d have to back out again because there’s no room to turn around. One is military and has a chain across to keep boats out. The canals near Piazzale Roma and Canale Scomenzera are places where I would never take anybody unless I was really certain of their paddling skills, because of the heavy traffic there. Those are the places where goods are loaded from trucks to cargo boats and vice versa.
