We love the Traghetto in Venice, it's easy and it is the best way to cross the Grand Canal enjoying a short gondola ride!!
We have 7 points along the canal between Train Station to St. Mark's Basin:
*The most important Traghetti for tourist - During The Feast of Madonna della Salute a temporary bridge is built on boats crossing the Grand Canal from the Traghetto of Santa Maria del Giglio to Salute so thousands of people can make the pilgrimage
Find the "Traghetto" sign, usually posted close the pier along the canal and stay in line waiting for the gondola, normally you shouldn't have to wait long if the service is running. When the traghetto arrives you can get on board and find a place to sit. Pay your fare to the oarsman as you board.
