Lake Wdzydze: paddling the Kashubian sea

The Kashubian sea - four arms of water laid out in a cross, a narrow strait beyond which the big water opens up, and a quiet you don't expect.

Wdzydze - the lake that flows four ways

Wdzydze is five connected waters with a total area of about 1,450 hectares, stretched along two perpendicular troughs: Jelenie to the north, Wdzydze to the south, Radolne to the west, Gołuń to the east. On the map those four arms form a cross, and that is what people in Kashubia call it - the Cross of the Wdzydze Lakes; the fifth lake in the complex is Słupinko. The water here reaches about seventy metres deep, which for a post-glacial lake is exceptional.

The name "the Kashubian sea" is no brochure trick - the landscape park itself uses it, and once you paddle out into the middle it is hard to argue with. A vast sheet of water, a shore slipping away into bays, islands on the horizon. It is also called the Great Water and the Szerzawa.

How to paddle a kayak on Wdzydze

The strongest impression comes from paddling onto the lake from the river side. The Wda flows down here from Lipusz to Radolne, that is, to the western arm of the cross. From there, through the narrow strait between the Niwka and Kozłowiec peninsulas, you paddle out onto the big water - and that is the moment worth coming here for. The tight passage opens suddenly onto a huge expanse.

The whole stretch of the trail from Lipusz through the lakes all the way to Borsk is rated easy and accessible to beginners. You will find put-in points at Wdzydze Kiszewskie, Gołuń, Wdzydze Tucholskie, Lipa and Borsk. On the trail itself, within the park, rest stops have been laid out near Schodno and Loryniec.

Where to go: peninsulas, islands, viewpoints

Wdzydze has seven islands with a total area of over one hundred and fifty hectares: Ostrów Wielki, Glonek, Ceronek, Sorka, Przerośla, Mielnica and Sidły.

It is better not to land on the islands. Contrary to what you can read in guidebooks, they are not a reserve - a reserve covering them is only proposed, and the only one established in the park remains Krwawe Doły. The reason for restraint is different and just as concrete: the islands have owners, and many species of bird live there. Paddling round these places brings more pleasure than stepping ashore.

A quiet with a legal basis

On Wdzydze you won't hear a motorboat or a jet ski. Within the landscape park, the use of motorboats on open water bodies is banned, introduced by a resolution of the provincial assembly. The exception is craft with an electric drive of up to five horsepower - the kind that cannot pick up enough speed to build a wave.

It is worth naming this precisely, because most descriptions of the lake speak of a "quiet zone". A quiet zone is something else - a separate legal institution, established by the county council, and there is none on Wdzydze. The effect for the kayaker is the same, but the source of the ban is different.

Safety: big water and the west wind

The greatest danger on Wdzydze is not obstacles in the water but the surface itself. In windy weather paddling across the lake can be dangerous because of the high waves. Westerly winds prevail over the lake, and the open water gives them several kilometres of fetch.

The practice is simple: in a stronger wind keep to the shore rather than cutting across the lake, and in a bigger wave point the bow of the kayak into it, not the side. Before you set off, check the weather forecast and the current water level.

The open-air museum by Lake Gołuń

By Lake Gołuń stands the Kashubian Ethnographic Park - the oldest open-air museum in the Polish lands. It was founded in 1906 by Teodora and Izydor Gulgowski, starting from an eighteenth-century cottage bought from a local farmer. Today it is twenty-two hectares and nearly fifty buildings from Kashubia and Kociewie.

The qualifier "in the Polish lands" matters here: the museum was created before independence was regained, under a different state, and that is precisely what makes it the first such place in this part of Europe.

The outflow at Borsk and on down the Wda

The Wda flows out of the complex at Borsk, at the southern end, and runs on towards Czarna Woda and Tleń. Right at the outflow there are weirs and a portage waits, so the end of the lake section means getting out onto the bank. Anyone who wants to link the big water with the river has a natural crossing here - and the whole Wda ahead of them.

Where to start
  • Wdzydze Kiszewskie (marina) - the main base on the lake - marina, rentals and the Wdzydzkie Oko viewing tower
  • Wdzydze Tucholskie - a marina on the eastern shore; from the viewpoint here you get the best view of Sorka island
  • Borsk (Wda outflow) - the southern end of the complex - this is where the Wda leaves the lake. A portage waits by the weirs
Route ideas
  1. 01
    The narrow passage onto the big water

    Here the lake narrows to little more than a hundred metres, and just beyond the neck it opens to its full width. It is the best moment of the whole trip - worth paddling through this way rather than taking a short cut.

  2. 02
    Sorka island

    Paddle right around it. From land it is best seen from the viewpoint at Wdzydze Tucholskie, but from the water it makes a better impression. You don't land on the islands - they have owners and nesting birds.

  3. 03
    Glonek island

    A smaller island in the middle part of the lake, a good turning point for a shorter loop from Wdzydze Tucholskie.

  4. 04
    Ostrów Mały island

    The southernmost of the islands, on the way to Borsk. It is convenient to combine it with a paddle out towards the Wda outflow.

  5. 05
    Sidły island

    The northern part of the lake, close to the neck - a natural target for a trip out from the marina at Wdzydze Kiszewskie.

  6. 06
    The middle of the big water

    This is where the name "the Kashubian sea" comes from - the shore is far off on every side. In wind, return along the shore rather than cutting straight across the lake.

How to paddle a kayak on Wdzydze? You plan the route yourself - it is a complex of five connected lakes in the shape of a cross, so there are several directions to choose from. You won't meet motorboats here, because within the park motorised craft are banned. Watch out for the wind, though: on such big, open water a wave builds fast, and the winds here blow mostly from the west.

Frequently asked questions about Lake Wdzydze:

How big is Lake Wdzydze?
Wdzydze is made up of five connected lakes with a total area of about 1,450 hectares. Four of them form the shape of a cross: Jelenie to the north, Wdzydze to the south, Radolne to the west and Gołuń to the east, and the fifth is Słupinko. The water here reaches about seventy metres deep.
Can you paddle a kayak or SUP on Lake Wdzydze?
Yes, and it is one of the more popular kayaking waters in Kashubia. The Wda trail from Lipusz through the lakes to Borsk is rated easy and accessible to beginners. What decides the difficulty here is the weather: this is big, open water.
Are there motorboats on Wdzydze?
No. Within the Wdzydze Landscape Park, the use of motorboats and jet skis on open water bodies is banned, introduced by a resolution of the Pomorskie provincial assembly. Only electric drives with a power of up to five horsepower are allowed. It is worth knowing that this is not a legal "quiet zone" - that is a different institution, which has not been established on Wdzydze.
Is Wdzydze safe for families?
In calm weather and close to the shore, yes. But bear in mind that in windy weather paddling across the lake can be dangerous because of the high waves, and westerly winds prevail over the water, with several kilometres of fetch here. With children it is better to paddle along the shore and give up crossing the big water when the wind is stronger.
Can you land on the islands of Lake Wdzydze?
Better not to. Contrary to a common belief, the islands are not a reserve - a reserve covering them is only proposed. The islands do, however, have landowners, and birds nest there, so it is wiser to paddle round them. The largest of them is Ostrów Wielki.
What is worth seeing while paddling on Wdzydze?
Paddling out onto the big water through the narrow strait between the Niwka and Kozłowiec peninsulas, rounding Ostrów Wielki, the Lipa peninsula and the Wdzydzkie Oko viewing tower at Wdzydze Kiszewskie. By Lake Gołuń lies the Kashubian Ethnographic Park - the oldest open-air museum in the Polish lands, founded in 1906 by Teodora and Izydor Gulgowski.
