Once inside the lagoon speed
limits come into force which unless otherwise
signposted are as follows:
a) General speed limit for the lagoon taken as
a whole : 20 km/h
b) General speed limit for the city of Venice
and it's historic centre: 11 km/h
c) Speed limit for more sensitive areas such
as the Grand Canal and smaller canals: 7 km/h
or even 5 km/h (Off-limits for non residents
anyway)
We recommend proceeding slowly and taking special
care when transiting the St. Mark's basin which
can be heavily congested. A map illustrating
the speed limits in the lagoon can be found by
