Although Venice is the city of canals, there is much to see just walking around the streets and lanes of Venice. With no cars, walking is easy and safe, but take note of your bearings! It would be easy to get lost!
There are many small shops off the main tourist path, including one we found that sold the clay masks typically associated with Venice. The Murano glass factory and showroom can also be found on a walk around Venice. (When I walk with my wife, I hold her hand. If I let go, she SHOPS!)
Some of the lanes/walkways take you past canals, and others lead to small footbridges across the canals. In many of these side streets there are magnificent views of the old canals and the historic buildings. It is also the key to finding a nice restaurant with reasonable prices. Those near the square are expensive and busy.
The hotel Danieli (a favourite haunt of the much honeymooned Liz Taylor) can be found by walking along the edge of the main waterway. Go inside for a peek at the ultimate in romantic luxury, but don't bother asking for a drink list. If you need to know the prices, you can't afford it! (This hotel is seriously expensive!)
We found a nice little takeaway selling foccacias with a good variety of fillings and for a reasonable price. For those who lack culture and refinement, there is a McDonald’s. We did not go all the way to Venice to eat burgers! The only problem with finding a small takeaway is finding somewhere to sit and eat!
So, if you are visiting Venice, leave the main square. Explore the side streets and laneways, and marvel at the old buildings set amongst the canals.
