Colleen, I imagine the island of Burano would be great, although quite a vaporetto ride from Venice. Away from the couple piazzas with lots of shops and restaurants, it is really a quaint fishing village, with small lanes, canals, lots of boats, with small houses all painted in various pastel colors -- pink, turquoise, pale blue and green, yellow -- and a very small town, neighborhood feel. Supposedly the tradition of colored houses started so that fisherman could spot their own homes from the water. Lots of great food there at a variety of restaurants too. From Burano, it is just a 5 minute vaporetto ride to the island of Torcello, which is basically very rural, with a 10-minute path leading from the vaporetto stop to the church complex, the oldest church where Venice was initially founded. Also from Burano, right by the vaporetto stop, there is a pedestrian bridge across to the island of Massorbo, which is also quite rural and to which almost no one goes.
