The Luga, the Svir, the Volkhov, and the Neva are all navigable and heavily user for cargo transport, however, there is no scheduled passenger navigation within the oblast, with exception of seasonal leisure river cruises from Saint-Petersburg. The Onega Canal, shared with Vologda Oblast, serves as a bypass of Lake Onega from the south. Similarly, the Ladoga Canal bypasses Lake Ladoga from the east, from the Svir to the Neva. It is a part of the Volga–Baltic Waterway. In contrast, the Tikhvinskaya water system, connecting the Syas and the Mologa, which provided access from the Ladoga to the river basin of the Volga, is disused. The trans-border Saimaa Canal connects Lake Saimaa in Finland with the Gulf of Finland, has special status, and is occasionally used for passenger navigation.
