The numerous vaporetto lines can be bewildering, too, and often the only option for getting where you want to go is to walk. Yellow signs, posted on many busy corners, point toward the major landmarks—San Marco, Rialto, Accademia, and so forth—but don't count on finding such markers once you're deep into residential neighbourhoods. Even buying a good map at a newsstand—the kind showing all street names and vaporetto routes—won't necessarily keep you from getting lost. To make matters worse, map apps on smart phones, for some reason, give frequently erroneous results for Venice.
Fortunately, as long as you maintain your patience, getting lost in Venice can be a pleasure. For one thing, being lost is a sign that you've escaped the tourist throngs. And although you might not find the Titian masterpiece you'd set out to see, you could wind up coming across an ageless bacaro (a traditional wine bar) or a quirky shop that turns out to be the highlight of your afternoon. Opportunities for such serendipity abound. Keep in mind that the city is self-contained: sooner or later, perhaps with the help of a patient native, you can rest assured you'll find your way home and have a story to tell.
