Biebrza: a wild land of marshes and elk

Biebrza - a wild land of marshes and elk

The Biebrza is the wildest lowland river in Poland and one of the most naturally valuable places in this part of Europe. It is about 165 km long and along almost its entire length flows through Biebrza National Park, surrounded by the largest natural marshes and wetlands in the country. Its current is very slow, and every year sweeping floodplains cover the valley, so the river resembles a moving lake spread among the reeds more than an ordinary river.

For a kayaker the Biebrza is an experience apart. The water is easy and forgiving, with no rapids or portages, but the route is long, remote and takes preparation. This is not a trail for a quick outing - it is a several-day expedition for those who want to see wild nature up close and don't mind the lack of comforts.

Where the Biebrza rises and where it flows

The Biebrza rises south of Nowy Dwór, in Podlaskie Voivodeship, close to the border with Belarus, and flows in an arc to the south-west. Along the way it passes Lipsk, Sztabin, Goniądz and Osowiec, until near Wizna it joins the Narew. The whole river measures about 165 km, and its basin covers more than 7,000 km².

Kayakers divide the Biebrza into three basins: Upper, Middle and Lower. The classic trail runs from Lipsk to Wizna and is about 140 km, which makes it a 7-9 day trip. The further down you go, the wider the valley becomes and the larger the floodplains - the lower reach is already vast, boundless wetland.

Biebrza National Park - the largest in Poland

Almost the entire river lies within Biebrza National Park, created in 1993. With an area of about 592 km² it is the largest national park in Poland. It protects above all the marshy Biebrza valley - the best-preserved and largest complex of peat bogs and wetlands in the country, and one of the most valuable in Europe.

It is precisely this wildness that makes the trail so special. The valley has hardly been altered by human hands: there are no embankments, no regulation and no development, and the river still meanders freely and spills over in spring. In return, the park imposes rules you need to know before you set off.

Elk, beavers and a bird paradise

The Biebrza is famous above all for its wildlife. It is home to the largest elk population in Poland - with a little luck you can see these huge animals wading among the reeds right beside the paddling route. Beavers, otters and wolves also live in the valley, and the water holds pike, tench and perch.

But it is the birds that have made the Biebrza most famous. The marshy meadows are one of the most important breeding grounds in Europe for the aquatic warbler - a small, vanishing bird for which the valley is of international importance - as well as the ruff, the black-tailed godwit and many species of water birds. In spring, during migration and courtship, thousands of birds gather over the valley, which is why the Biebrza is a destination for watchers from all over the world.

Floodplains, basins and Osowiec Fortress

The Biebrza's character changes with the season. In spring, after the thaw, floodplains reaching to the horizon cover the valley - the best time for watching wildlife, but also the hardest to navigate. In summer the water drops, the channel grows narrower and the paddling more comfortable, though in the heat the shallower stretches can be a nuisance.

In the Lower Basin, at Osowiec, the river passes beside Osowiec Fortress - a mighty tsarist fortification from the turn of the 19th and 20th centuries, still partly in military use today. Along the valley also runs the famous Tsar's Road (Carska Droga), a route laid out across the marshes from which elk and birds are easiest to spot.

Stretches of the Biebrza trip: from Lipsk to Wizna

The Biebrza is best planned in stretches. The upper stretch, from Lipsk to Sztabin, still leads through a wooded valley near the Augustów Canal - a calm introduction to the land of marshes. The middle stretch, from Sztabin to Goniądz, opens the first broad floodplains and the best birding grounds. The lower stretch, from Goniądz to Wizna, is the wildest part of the trail: boundless wetlands, Osowiec Fortress and the mouth at the Narew. You can see every stretch on the map below - in "Close to nature" mode, with facilities and water levels along the way. And if you'd rather plan the trip your own way, you can draw your own route in "Your own way" mode.

Entry rules and preparing for the Biebrza trip

Paddling the Biebrza takes some preparation. Because the river flows through a national park, a water-trail entry card is required for paddling, and you must keep to the marked trail. During the breeding season some stretches are additionally protected - on the Osowiec-Brzostowo stretch a separate permit is required from 1 January to 30 June. It is worth checking the current rules and fees on the park's website before you set off.

The valley's international importance is confirmed by the Biebrza's listing under the Ramsar Convention - the register of the world's most valuable wetlands. Every spring the valley becomes one of the most important stopovers in Europe for migrating water and marsh birds.

You also have to remember that the valley is remote: it can be a long way between villages, and supplies and places to stay must be planned in advance. The best times are spring, when the valley teems with life, and summer, more comfortable for camping. Before you set off, check the current water level. Near Wizna the Biebrza gives its waters to the Narew - a river you can also paddle, described in the article on the Narew in Podlasie.
