Ferries can shorten your path across the Vltava river. All ferries in Prague are included in the Prague Integrated Transport (PID) system, therefore passengers can use PID tickets. Currently there are 6 lines: P1, P2, P3, P5, P6 and P7.
Ferries P1 and P2 are operated for the whole year, ferries P3, P5, P6 and P7 only during season (April to October). Timetables are available on-line.
