Rospuda: the wild river of Suwalszczyzna

Rospuda: a wild river and a famous valley

The Rospuda is one of the most natural rivers of Suwalszczyzna. It flows through a chain of narrow, post-glacial lakes and a marshy, meandering valley in the buffer zone of the Augustów Forest, and its lower reach became famous across Poland as the scene of a loud defence against a road being built. For the paddler it is a demanding trail and, at times, utterly deserted.

Where the Rospuda flows and how long the trail is

The Rospuda begins on the Suwałki Lake District and flows south down a chain of nine narrow ribbon lakes – from Rospuda Filipowska, through Kamienne, Długie, Garbaś and the rest, all the way to Rospuda Augustowska. The whole river, counted together with the Netta into which its lower reach passes, is about 102 kilometres; the Netta itself flows on into the Biebrza. The kayak trail is shorter – the classic Supienie-Augustów stretch is about 65 kilometres and usually takes several days. The finish falls at Augustów, on Lake Necko, from where it is a short way to the Augustów Canal.

Is the Rospuda difficult? Who is this trail for

The Rospuda is among the demanding rivers. In the PTTK classification its difficulty is given as ZWB-ZWC – it is a two-natured river, in which calm lake sections with a gentle current alternate with almost mountain-like fragments: swift, stony, with a faster flow. In summer, at lower water, the gentler sections are within reach of less experienced paddlers too, best under an operator's care. Outside the season the current speeds up, and then the trail is rather for people with experience.

Safety on the Rospuda: the stretch with no way ashore

The most important thing on the Rospuda concerns the lower reach. There the river meanders through broad, marshy meadows, and on one stretch – about three to four hours of paddling – there is nowhere to get ashore, because the banks are completely inaccessible. This is not a ban, only the nature of the terrain: before this stretch you must attend to every need, carry water and food with you, and not count on a stop until its end. It is also worth checking the weather, because on a deserted marsh there is nowhere to shelter. There is more on preparing for tougher water in the guide to safety on the water.

A river in a protected land: what you need to know

The Rospuda Valley is under protection – it belongs to the Natura 2000 areas (Ostoja Augustowska and Puszcza Augustowska), and its most precious, peat-bog fragment is protected by the Rospuda Valley reserve. Trips run down the river itself to Augustów, and in the available sources there is no administrative ban on paddling the channel. The protection concerns above all the banks: unique peat bogs and mires, which must not be walked on. So you paddle the channel, do not step onto the marshes, and if you have to stop – only in places clearly meant for it. It is worth confirming the detailed rules within the reserve's boundaries before you set off, with the trip operator or with the regional directorate for environmental protection in Białystok. Sosnowsky's hogweed also occurs in the valley, so it is better not to go ashore at random, wild spots.

Portages and obstacles on the trail

There are two fixed portages on the route. The first falls at the mill in Bakałarzewo – the kayak is carried along the left bank for about fifty metres. The second is at the small hydro power station in Małe Raczki, along the right bank, for some sixty metres. Beyond them the Rospuda can be hard work on natural obstacles: the channel holds stony shallows where you sometimes have to get out and drag the kayak, fallen trees, and in places stakes driven into the bed. That is why you paddle here carefully, watching ahead of the bow.

Stretches of the Rospuda trip: Filipów-Augustów

The whole trail divides well into three days, marked out naturally by the portages and the change in the river's character. The upper stretch runs through the ribbon lakes, the middle through the most varied, stony channel, and the lower through the deserted, marshy valley all the way to Augustów.

The Rospuda Valley: wild nature and a loud defence

The Rospuda is widely known not only among paddlers. Its valley is a vast, well-preserved peat bog with rare plants and birdlife, and that is exactly why it became the scene of one of the loudest disputes over nature in Poland. A dozen or so years ago an expressway was to cross the bogs; the protests in defence of the valley echoed across the whole country, and the variant through the valley was ultimately abandoned. In 2024 the most precious fragment of the valley was made a nature reserve.

Where to start the trip and rent a kayak

The classic trip begins at the top of the chain of lakes, around Filipów and Supienie, and finishes at Augustów on Lake Necko. Kayaks are hired out by trip operators in Augustów – they usually deliver the equipment to the start, which is a great help on a one-way, multi-day route. How to match the stretch to the weather, the water level and the group, I explain in the guide on how to choose a trip route.
