The Vistula Lagoon is part of the IWW E70 and, at the same time, is classified as sea waters. It stretches over an area of 838 sq km, of which 328 sq km are on the Polish side of the border. Along the Polish coast, there are 10 ports and marinas.
Navigation on the Jagielloński Canal is possible without major problems. The banks are largely overgrown with reeds and there are long stretches where the banks are reinforced with a wooden palisade. Past the flood gates, at the entrance to the Jagielloński Canal from the direction of the Nogat (km 51.6), there is sandy clearing convenient for mooring.
Along this nearly 140 km long section of the Vistula, mooring sites are scarce. One can stop on sandy beaches between groynes but one must be watching out for fishing nets and protruding stony revetments.
The pleasant sandy and green banks of the Warta may tempt us to make a stop, but the washed out and, in many cases, invisible groynes can make it impossible. Therefore, it is more advisable to use yacht club marinas, small harbours or loading wharves.
The Oder does not abound in harbours or sports club marinas which would encourage to leisure activities on the water. From all the harbours along this section of the river, only the marina in Kostrzyn at the Warta River confluence (km 617.6) is worth mentioning.
Travelling on the Nogat, we pass through four canal locks. At the entrance to the Nogat, we find the modern 'Biała Góra' marina (km 0.5), built in 2012 as one of the investments of the Żuławy Loop Project.
Past the lock in Przegalina (km 936) on the Martwa Wisła, there is a dock for the Regional Water Management Board in Gdańsk, and a little further on, a modern marina in Błotnik, built as one of the key investments of the Żuławy Loop Project.
