The Brda – paddling artery of the Tuchola Forest

The Brda is one of the best-documented and most-paddled kayak trails in Poland. It runs 238 km from the Bytów Lakeland through the heart of the Tuchola Forest to Bydgoszcz, and the waterway open to kayaks is about 233 km, from Świeszyn to Brdyujście. It leads through pine forest and a chain of ribbon lakes, along the boundary of the 'Bory Tucholskie' National Park and through the Tuchola Landscape Park – giving you a route you can paddle in a single day on a chosen stretch, or spread over a week with camp stops.

The Brda route: from where to where, and how to split it

The classic trail starts on the upper course near Świeszyn and ends in Bydgoszcz, where the Brda flows into the Vistula at Brdyujście. The river is well set up and divides naturally into day-long stretches of 15–25 km, marked out by campsites, water stations and villages with access to the water. The most popular part is the middle course in the heart of the Tuchola Forest – between Swornegacie, Męcikał, Rytel, Woziwoda and Tuchola – where the river is narrow, clean and winding. Below Koronowo the Brda flows into the Koronowo Reservoir and becomes wider and more 'lake-like', while the final stretch runs through Bydgoszcz.

How long does the Brda take? Which stretches for a single day

For a single day, the stretch most often recommended is Rytel-Woziwoda (about 17.6 km) – reckoned by many rentals to be the finest fragment of the whole river – and Woziwoda-Rudzki Most (about 20.5 km) near Tuchola. Both fit into a few hours of relaxed paddling with breaks. Those with more time link the stretches into a multi-day expedition; paddling the whole trail takes about 10–12 days. The upper course above the Forest is less frequented and can be demanding, so for a first trip it is better to choose the marked middle stretches.

Is the Brda difficult? Who the trail is for

The middle Brda in the Tuchola Forest is moderate water, open to beginners and families too – especially the Rytel-Woziwoda and Woziwoda-Rudzki Most stretches, recommended for people with little experience. The river is lively here: in places it speeds up over riffles, fallen trees can lie in it, and through the first kilometres of the upper course (for example Nowa Brda-Przechlewo) it runs through a narrower, more dynamic channel that sources describe as harder and meant rather for the experienced. Below the Koronowo Reservoir comes open, lake-like water, where wind and waves matter. In short: matching the stretch to the group's level is more important here than on an easy lowland river.

Obstacles and portages on the Brda

There are several places on the Brda trail where the kayak has to be carried. The most important is the dam at Mylof – the oldest water dam in Poland, built in 1849 – where kayaks are carried around along the left bank (the forest district provides a trolley for moving the gear). Further down there are portages at the hydro plants: at Samociążek (about 200 m), at Tryszczyn (a short one, about 60–80 m) and at Smukała (about 100 m); on the upper course there is sometimes a short portage at Stara Brda too. In Bydgoszcz the trail is closed off by the historic Municipal Lock. Apart from that, you have to reckon with fallen trees and narrow riffles, typical of a forest river. At portages the same rule applies as everywhere: you carry the kayak, you do not lead it through the obstacle.

The Tuchola Forest: what you'll see along the way

The Brda is the axis of one of the largest forest complexes in Poland. The trail skirts the 'Bory Tucholskie' National Park and leads through the 'Brda River Valley' reserve, and along the way it passes a chain of ribbon lakes: Charzykowskie, Karsińskie, Witoczno and – on the lower course – the vast Koronowo Reservoir. The whole region lies within the Tuchola Forest Biosphere Reserve, inscribed on the UNESCO list. It is a landscape of pine forest, clear lakes and sandy banks, with rich birdlife – one of the reasons the Brda is regarded as a route 'close to nature'.

The Grand Brda Canal and the aqueduct at Fojutowo

One of the country's more interesting hydro-engineering structures is tied to the Brda – the Grand Brda Canal. It was built in the mid-19th century (around 1849) to irrigate the sandy land around Czersk, and it is several dozen kilometres long. Its most famous feature is the aqueduct at Fojutowo: the canal flows above the Czerska Struga, forming a crossing of two watercourses on two levels. It is a recognisable regional attraction and a frequent destination for family trips along the canal itself, calmer than the river.

Where to rent a kayak and how to get back

The Brda is one of the best-served trails in Poland – rentals operate in Rytel, Swornegacie, Męcikał, Woziwoda and around Tleń and Koronowo, among others, usually delivering the gear to the start and collecting it at the finish. This makes it easy to plan a 'point-to-point' trip without your own kayak and with no trouble getting back. Overnight stops along the route are mainly campsites and water stations, including PTTK stations by Lake Charzykowskie and by Witoczno.

When to paddle: water level and season

The Brda is a relatively stable river – it is fed by lakes, so it does not dry out as easily as small lowland rivers, and the season runs from late spring to early autumn. Even so, before you set off it is worth checking the current water level at the nearest gauge: a very high level speeds up the current and floods the portages, while a very low one exposes the riffles. It is most pleasant to paddle in summer, at a settled, average level.

  1. 01
    Stara Brda-Swornegacie~64 km

    The upper course through the Bytów and Krajna Lakelands – a narrower, in places more dynamic channel, less frequented. Higher up, from Świeszyn, fallen trees and shallows appear in the river, past which the kayak has to be towed.

  2. 02
    Swornegacie-Rytel~27 km

    Entering the Tuchola Forest: Lakes Charzykowskie and Karsińskie, Męcikał, a clean forest river. Beyond Mylof, a portage at the hydro plant, about 200 m.

  3. 03
    Rytel-Woziwoda~18 km

    The most often recommended day-long stretch – a narrow, winding river in the heart of the forest, below the dam at Mylof.

  4. 04
    Woziwoda-Rudzki Most~20 km

    A picturesque stretch near Tuchola, within the 'Brda River Valley' reserve, which is open to paddlers. From Rudzki Most it is still about 2 km overland to Tuchola itself.

  5. 05
    Rudzki Most-Bydgoszcz~76 km

    The longest and most demanding fragment: first Piekiełko below Świt, where the river speeds up between boulders, then about 25 km of open water on the Koronowo Reservoir, then portages at the hydro plants at Samociążek, Tryszczyn and Smukała, and finally locking through in Bydgoszcz.

Frequently asked questions about paddling the Brda:

How long is the Brda?
The Brda is 238 km long, and the kayak trail marked along it is 233 km, from Świeszyn to Brdyujście in Bydgoszcz. Nobody paddles it in one go: the river divides naturally into stretches of 15–25 km that can be covered in a single day.
Which stretch of the Brda should you choose for a single day?
The most often recommended is Rytel-Woziwoda, about 18 km of a narrow, winding river in the middle of the forest. The neighbouring Woziwoda-Rudzki Most, which leads through the 'Brda River Valley' reserve, is praised just as much. Both have good access and rental support.
Is paddling the Brda difficult? Who is it for?
The PTTK classifies the trail as ZWB, meaning without major technical difficulty. The upper and middle stretches are calm and suit beginners and families. It gets harder below Świt, at Piekiełko, where the river narrows and speeds up between boulders - there the level of difficulty depends on the water level. The lower course, in turn, means long paddling across open water.
What portages are there on the Brda?
Five: Stara Brda (about 100 m), Mylof (about 200 m), Samociążek (about 200 m), Tryszczyn (from 80 to 100 m - sources give different figures) and Smukała (about 100 m). In Bydgoszcz you do not carry the kayaks but lock through the Municipal Lock. Higher up, on the upper course, there are also fallen trees and shallows.
Can you paddle the Brda through the 'Bory Tucholskie' National Park?
No, and there is no need to. Water sports, swimming and sailing are banned in the park, and it is visited only along marked land trails. The Brda kayak trail runs along its boundary and buffer zone, through the Tuchola and Zabory Landscape Parks, so the trip takes place outside the national park.
What will you see while paddling the Brda?
The 'Brda River Valley' reserve below Woziwoda, which is open to paddlers, Piekiełko near Świt, a chain of ribbon lakes including Charzykowskie and Karsińskie, and on the lower course the Koronowo Reservoir - a body of water covering 1,560 ha and 36 km long, created between 1956 and 1962. The whole region lies within the Tuchola Forest Biosphere Reserve.
When is the best time to paddle the Brda?
The season is long, and the Brda is one of those rivers on which even winter trips are organised. In summer the water can be warm and clear, in spring higher and faster. Before you set off, check the current water level - on the upper course, at low water it is easy to hit shallows.
