After lunch at nearby Campo Santa Margarita, take a "passegiata" (short walk) along the zattere overlooking the Canal della Guidecca. This wide promenade (a rarity in Venice!) was originally built as a landing spot for timber in the 1500's.
These days you can see Venetians running along the zattere or people sitting on benches enjoying the view of the outlying islands. You'll also pass by a lot of government owned offices (i.e. French embassy) or see people having lunches at one of the floating restaurants along the promenade. At its most eastern point where the Grand Canal and the Guidecca meet, you can view Piazza San Marco and also visit Punta della Dogana, a former customs office which now houses contemporary art. read more
