The Grand Canal is a canal in Venice, Italy. It forms one of the major water-traffic corridors in the city. Public transport is provided by water buses (Italian: vaporetti; Venetian: vaporeti) and private water taxis, and many tourists explore the canal by gondola. One end of the canal leads into the lagoon near the Santa Lucia railway station and the other end leads into Saint Mark Basin; in between, it makes a large reverse-S shape through the central districts (sestieri) of Venice. It is 3.8 km long, and 30 to 90 m wide, with an average depth of five meters (16.5 ft).
