Is 2 days enough in Venice? Two days is enough to see the main sights and get out to the islands without rushing. This 2-day Venice itinerary covers the centre on foot on day 1 and uses the water bus (vaporetto) on day 2.
Day 1 is iconic Venice: St Mark's Basilica, the Doge's Palace and the Bridge of Sighs, the Rialto Bridge over the Grand Canal, then an evening in Dorsoduro. It's about 2.2 km of walking between stops.
Day 2 is the islands and hidden Venice: Murano for glassmaking, Burano for its colourful houses, back to the city for Libreria Acqua Alta, then cicchetti and wine in Cannaregio.
