Because the historic center of Venice is entirely car-free and composed of islands connected by canals, there are no "buses" in the traditional sense on the main islands. Instead, Venice offers a Hop-On Hop-Off Eco Boat (often called the "Batello" tour). In 2026, these boats operate on a specific circuit that includes major landmarks like St. Mark's Square, the Zattere, and the islands of Murano, Burano, and Torcello. A single ticket (typically valid for 24 or 48 hours) allows you to disembark at any of the designated stops and rejoin a later boat. While there are traditional hop-on hop-off buses in Mestre (the mainland part of Venice), they do not cross the bridge into the historic lagoon city. For the classic "floating city" experience, the boat tour is the equivalent service, providing panoramic views of the Grand Canal and the Venetian lagoon without the crowds of the standard "Vaporetto" public water buses.
