Murano and Burano are two smaller islands that are part of the Venice archipelago and historically, Morano is where the glass-blowing factories are located and Burano was where the fishermen lived. Because of this, they are both much simpler in terms of architecture, the working class neighourhoods, so to speak, and quite a contrast to the sumptuous regality of Venice proper. Burano in particular is very pretty and colourful and, to our relief, much less crowded. People actually still live here, the fountains have water, the pace is much more laid-back and we spent a blissful afternoon wandering the tiny lanes and sitting with our feet in the water.
Murano and Burano are both easily accessible with the vaporetto public transport system, if you get a 2 or 3 day pass you can then travel as much as you like during the time period, its definitely the cheapest way to do it. Italy is also very dog friendly, like most of Europe (Portugal being a notable exception… 😦 ) and dogs are more than welcome on public transport as long as they are well behaved, so travelling with Zé was no stress.
