Venice is expensive and crowded with tourists, but even that can't ruin the magic of its atmosphere and charm--there's just nowhere else like it. Exploring is best done by wandering on foot, allowing oneself to be "lost with purpose" in the labyrinthine network of small alleyways and canals and to stumble upon hidden gems. Local restaurants and hole-in-the-wall wine shops are enjoyed away from the crowds of tour groups and aggressive vendors hawking bizarre toys and selfie sticks.
Insider Tip:The unlimited public transit pass will pay for itself if you are here for more than even 36 hours. Water taxis are useful and an easy way to get a gorgeous sightseeing ride without paying for a gondola. Avoid the crowds in the main square and seek out quieter, more authentic restaurants on streets further into the labyrinth.
