The Vistula Lagoon, Żuławy and the Spit
Sea water at the mouth of the Vistula: the Vistula Lagoon is a shallow, brackish body of water behind the Vistula Spit - a different element from a river. A demanding route for the aware: wave, wind and weather decide, with the Żuławy and the Żuławy Loop in the background.
The Vistula Lagoon - sea water at the mouth of the Vistula
The Vistula Lagoon is a completely different world from a river. It is a broad, brackish body of water at the mouth of the Vistula, separated from the open Baltic by the narrow Vistula Spit. It covers 838 km², of which 328 km² lie on the Polish side - the rest belongs to Russia, to the Kaliningrad Oblast. The state border runs through the lagoon, and it is at the same time the external border of the European Union - crossing it is illegal. The border is not marked on the ground in any way visible from a kayak, so when planning a route in the eastern part of the lagoon, keep to the map and well clear of the border line. It is about 91 km long and from 6.8 to 13 km wide, but it is also very shallow: the average depth is a mere 2.7 m, and the water level can change by as much as a metre and a half in a day, because the wind pushes it in and drags it out, while the greatest depth on the Polish side is about 5.1 m. The bottom is muddy, and the water brackish - the salinity rises towards the sea, from about 2.2 per mille off Krynica Morska to over 5 per mille closer to the strait.
The lagoon connects with the open sea in two places. For centuries this was the Strait of Piława on the Russian side, at Baltiysk. Since 17 September 2022 there has been a second connection - the Vistula Spit Canal (Przekop Mierzei Wiślanej), a shipping canal with a lock, cutting across the spit near Skowronki and giving Poland its own route from the lagoon to the Baltic.
Paddling the lagoon - how it differs from a river and what to watch for
This is the most important thing to understand: the lagoon behaves like the sea, even though it lies inland. On a river the current carries you, and your worst enemy is a fallen tree. Here there is practically no current - everything depends on the wind. And on shallow, open water the wind can, in a quarter of an hour, build a short, steep and tiring wave that is far more dangerous for a kayak than the calm flow of a river.
On top of that come the shallowness and the muddy bottom. The southern part, Zatoka Elbląska (the Bay of Elbląg), is in places barely 1-1.5 m deep, while the marked shipping channels used by larger vessels are at least 2.2 m. A kayak has one advantage here - it will go where a boat would run aground or get stuck in the reeds - but you have to keep track of where you are.
Put on your life jacket and adjust it while still on the shore. The rules on the lagoon are simple and absolute: check the wind forecast before every outing and do not set out in a stronger wind. Keep close to the shore and paddle along it, not across the open water. The lagoon is water for people with experience, ideally in a sea or touring kayak, not a light river one. Beginners will feel safer on the sheltered rivers of the Żuławy Loop, described below.
An important note about the trail: the Vistula Lagoon has no marked, waymarked kayak trail divided into stretches, like the rivers in our atlas. You plan the route yourself - along the shore, between the ports at Tolkmicko, Frombork, Kadyny or Krynica Morska, always depending on the weather. The only waymarked water route in the area is the Żuławy Loop, but it runs mainly along the rivers and canals of the Żuławy and is designed more for motorboats and sailing boats than for kayaks. That is why the map below shows the water itself and its shores, with no route drawn in.
Where to stay and logistics
Here too it is different from a river. On the lagoon there is no "wild camping on the water" - you plan your overnight stops in ports, marinas and moorings, of which there are plenty in the region, because the whole area is tied together by the tourist route of the Żuławy Loop. You will find jetties and marinas in Elbląg, Tolkmicko, Kąty Rybackie, Krynica Morska and Nowa Pasłęka, among others, while campsites and resort lodgings operate on the Spit. So you plan the trip from port to port, checking the weather in advance - more like a sea voyage than a spontaneous paddle.
Nature
The nature here is absolutely top-flight, and it is often the main reason to come. The Vistula Spit is protected by the Vistula Spit Landscape Park, created in 1985, in which almost everything is dunes and coastal pine woods - forests make up about 90 percent of its area. Within the park lie two reserves - Buki Mierzei Wiślanej and Kąty Rybackie - and in its buffer zone, Mewia Łacha.
The most famous is the Kąty Rybackie reserve, protecting the largest colony of great cormorants in Poland and one of the largest in Europe, and beside it the second-largest grey heron colony in the country. During one count more than 11,000 nests were tallied here. The sight and sound of thousands of birds in the treetops is enormously impressive - though the trees, under the weight of the nests and guano, gradually die off, creating a bare, "lunar" landscape. The Mewia Łacha reserve at the mouth of the Vistula, in turn, is famous for its gulls, terns and the growing numbers of grey seals hauling out on the sandbars.
The lagoon itself is one of the most important refuges for water and marsh birds in this part of Europe, covered by the Natura 2000 network. The shallow, overgrowing water, the reedbeds of Zatoka Elbląska and the mouth of the Nogat are a paradise for swans, cormorants, geese, ducks, grebes and terns, and in spring and autumn thousands of migrating birds stop here. A separate treasure is nearby Lake Druzno by Elbląg - a shallow, deltaic lake, a reserve where about 200 bird species nest; it is covered by the Ramsar Convention as a wetland of international importance.
There is plenty going on in the water too. The lagoon is home to pikeperch, bream, roach, perch and eels, and migratory fish such as the vimba enter it too, while herring look in from the sea. It has been a fishing water for centuries - hence names like Kąty Rybackie ("Fishermen's Corners") - and to this day you can still meet traditional boats on it.
The Żuławy delta - land wrested from the water
To the south and west of the lagoon stretch the Żuławy Wiślane - the great, flat delta of the Vistula, some 1,700 km² in area. It is one of the most extraordinary landscapes in Poland, because a large part of it lies below sea level. This is where the country's greatest depression is: the lowest point in Poland is in the village of Marzęcino, 2.2 m below sea level (until 2022 the record belonged to Raczki Elbląskie, 1.8 m below). Much of this land was once the bed of the lagoon and emerged only thanks to the work of pumps.
The Żuławy is a landscape created entirely by human hand - a network of canals, dykes, locks and pumping stations that drain the depressed polders and protect them from flooding. Without this constant work the region would simply return underwater.
Behind it lies an exceptional settlement history. From the 16th century settlers came here from the North Sea - from today's Netherlands, Frisia, Germany and Denmark - known as Olędrzy, among them Mennonites. They brought with them the art of draining and cultivating waterlogged land: they dug canals, raised terps - artificial mounds protecting farmsteads from the water - and built the characteristic arcaded houses. The finest surviving examples of these 18th-century houses can be seen in Trutnowy, Różyny, Koszwały and Miłocin. The Mennonites also left quiet country cemeteries. This heritage gives the Żuławy an atmosphere found nowhere else in Poland - part Dutch, part all its own.
The Vistula Spit - dunes, pine woods and resorts
The Vistula Spit is a narrow, sandy bar of land separating the lagoon from the Baltic. In all it is about 96 km long, of which 59 km is in Poland, at a width of 1-2 km. On one side you have the sea, on the other the lagoon, and in between dunes and fragrant pine woods.
Several places worth remembering lie along the spit. Krynica Morska is the most popular resort, with a port, a lighthouse and beaches. Kąty Rybackie is famous for its cormorant reserve and its former fishing trade. Sztutowo is a difficult but important place - the German concentration camp Stutthof operated here, today a museum and place of remembrance that cannot be passed over when speaking of this region. Further east, by Piaski, the spit reaches the border with Russia. To the west it is closed off by Sobieszewo Island with the Mewia Łacha reserve at the mouth of the Vistula. Through the middle of the spit runs today's Przekop canal, from 2022.
The nearby rivers and the Żuławy Loop
For a paddler, the most interesting thing is that the lagoon is only part of a larger world of water. The whole region is tied together by the Żuławy Loop - a tourist water route of about 303 km, part of the International Waterway E70. It links the waters of the Vistula, the Dead Vistula (Martwa Wisła), the Szkarpawa, the Vistula Królewiecka, the Nogat and the Vistula Śmiała with the lagoon itself, forming a network of routes for every taste.
A few of these rivers are worth knowing by name. The Nogat is the old, main arm of the Vistula - it leads straight to Malbork and flows into the lagoon, and on its bank stands the largest brick castle in the world. The Szkarpawa and the Vistula Królewiecka are calm, quiet rivers for those seeking closeness to nature away from the bustle. The Elbląg river, in turn, has an urban feel, with drawbridges, and links the lagoon with Lake Druzno and the famous Elbląg Canal. From the east, from the Warmia side, the Pasłęka and the Bauda also flow into the lagoon.
The Elbląg Canal deserves a sentence of its own - one of the most extraordinary monuments of hydro-engineering in the world. Designed in the 19th century by Georg Jacob Steenke, it carries ships across a system of five slipways, on which vessels overcome the difference in levels on trolleys running on rails - they literally sail over land. The whole waterway is 127.5 km long and reaches deep into the lake district.
Towns worth visiting
The great advantage of this region is that paddling is easy to combine with visiting places of the first importance.
Elbląg is the natural gateway to the lagoon - a city with a rebuilt old town, a port, the start of the Elbląg Canal and Lake Druzno next door. A good place to start or end a trip.
Frombork lies right on the lagoon and is one of the most important addresses in the history of science. This is where Nicolaus Copernicus lived, worked and was buried - in the 14th-century Gothic cathedral on Cathedral Hill. Today the Copernicus museum, a planetarium, a Foucault pendulum and the famous organ music festival, held since 1967, await here.
Malbork, though it lies not on the lagoon itself but on the Nogat, is a compulsory stop. The Teutonic castle, raised from the 13th century as the order's capital, is the largest brick fortress in the world and a UNESCO site. You can reach it up the Nogat and stay overnight at its marina.
Also within reach are smaller but charming places on the eastern shore - Tolkmicko, Kadyny or Braniewo in Warmia - and Gdańsk to the west.
In summary
The Vistula Lagoon, with the Żuławy and the Spit, is a region where water means something completely different from a river. It is a sea-like sheet of water instead of a current, land wrested from the sea instead of a wild valley, Mennonite houses and Teutonic castles instead of forest fastnesses. You paddle here more carefully and with an eye on the wind, but in return you get one of the richest bird refuges in Poland, an exceptional settlement history and the chance to reach, from the deck of a kayak, the walls of Malbork or Copernicus's cathedral. This is water for those who want something more than a paddle.
