Especially recommended with kids:

Feeding pigeons on Piazza San Marco: a fun activity for all.

Vaporetto down the grand canal: while your children will have fun riding the boat, you will be able to take in the breathtaking scenery of the palaces bordering the grand canal.

Doges Palace secret itinerary: your guide will captivate you with the story of Casanova's daring escape.

Glassmaking demonstrations: Beware of pushy salespeople who will trick you into a "free" boat ride to Murano, but fail to mention that it is only free if you buy something from their shops. However, make sure to visit one of the fascinating furnaces in either Venice or Murano.

Murano Glass is one of the trademarks of Venice. Since the 12th century, they have been making glass on the island of Murano. Originally it was made in Venice but they moved to spare Venice the danger of fires. You can get to Murano by vaporetto or by private water taxi. There you can go to the Museo Vetrairo, or Glass Museum. The Museum is a 17th century palace and a wonderful place to see the rare and beautiful glass works of art. In the entrance of the Museum, is a glass sculpture made by the American artist, Dale Chihuly. You can wander the rooms and gardens for hours looking at breathtaking works of glass art and you can spend some time in the gift shop, too.

Burano: this small island has rainbow-colored houses, and  makes a fun day trip.

Lido di Venezia: the beach can provide a restful moment away from the bustle of the city and give children a chance to have some fun.

Gelato--Kids of all ages enjoy stopping for gelato!

Campanille--Located in the Piazza San Marco, ride the elevator to the top for amazing views.  If your children have sensative ears, bring some ear plugs in case the bells toll.  Be sure to bring the camera.
