Bóbr: a wild valley and the gorges of Lower Silesia

Bóbr - a wild valley and the gorges of Lower Silesia

The Bóbr is one of the most beautiful and most varied kayaking rivers in south-western Poland, regarded as the flagship waterway of Lower Silesia. It is about 272 km long and one of the longest left-bank tributaries of the Oder. Over a relatively short distance it changes character like few other Polish rivers: it begins as a mountain stream in the Krkonoše, squeezes through rocky gorges, spreads out into dammed lakes, and in its lower reaches flows calmly through forests and lowland plains.

Its popularity comes from the landscape - the incised valley, sheer slopes, castles and dams - and from its closeness to Jelenia Góra and the whole Sudeten tourist base. The Bóbr is not, however, a river for everyone all year round: the upper reaches can be demanding, and along its whole length you have to reckon with numerous portages at dams and weirs. That is why kayakers most often pick specific, well-tried stretches - from the gentle valley below Wleń to longer, multi-day expeditions.

Where the Bóbr rises and where it flows

The Bóbr rises in the Czech Krkonoše, at the foot of Mount Bobrowy Stok, at about 780 metres above sea level. After a few kilometres it flows into Poland and heads north, leaving the mountains around Jelenia Góra. From there, through Wleń, Lwówek Śląski, Bolesławiec, Szprotawa and Żagań, it flows all the way to the mouth on the Oder near Krosno Odrzańskie. The whole river measures about 272 km, and its basin covers nearly 5,900 km².

Most of the river is open to kayakers, though paddling all of it is a multi-stage expedition. The most written-about and most scenic part is the mountain and foothill stretch - from Jelenia Góra, through the Bóbr valley, to Bolesławiec. Below that the river becomes lowland and calmer, passing the Lower Silesian Forest.

The Borowy Jar gorge and the dammed lakes

The most dramatic stretch of the Bóbr lies just above Jelenia Góra. This is the Borowy Jar gorge - here the river forces its way through a deep valley with sheer, rocky banks, on the edge of the Rudawy Janowickie. It is reckoned one of the most beautiful river gorges in the Sudetes.

Below it the Bóbr flows into a chain of dammed lakes. The largest of them, Lake Pilchowickie, is held back by the mighty dam at Pilchowice - built in 1902-1912, 62 metres high and considered the largest stone dam in Poland. The reservoir holds about 50 million cubic metres of water. Right beside it stands the historic railway bridge of 1906, thrown across the river valley. For a kayaker the dam means the end of the stretch: you may not come closer than 200 metres to its crest. The descent down the right bank is steep and some 800 metres long, so the guidebooks advise against that portage and recommend landing on the left bank by the jetty and carting the kayaks overland below the dam, to Nielestno. At the barrages in Wrzeszczyn and Bobrowice a simple portage is enough.

The Bóbr Valley Landscape Park and its wildlife

The river's middle reaches, between Jelenia Góra and Lwówek Śląski, take in the Bóbr Valley Landscape Park, established in 1989. It protects one of the loveliest stretches - the river flowing through a deeply incised valley, between wooded slopes, old forests and rocky outcrops.

It is also a good place for watching wildlife. Along the water you can spot kingfishers, dippers and herons, and in the valley the traces of beavers - after which, as the name itself suggests, the river is named. Deciduous woods and forests cover the steep slopes, and in spring the Bóbr valley is one of the greenest corners of Lower Silesia.

Wleń and Lenno castle - one of the oldest in Poland

The heart of the valley is Wleń, a small town crowned by Wleń castle, known as Lenno. It is reckoned one of the oldest stone castles in Poland - its stone construction was begun back in the late 12th century, on the initiative of Duke Bolesław the Tall. The Romanesque walls have stood here for about 850 years.

The stretch of the Bóbr valley around Wleń is also the most popular with kayakers. Routes such as Wleń-Lwówek Śląski are easier than the mountain start and best suited to a one-day trip - which is why family and beginner outings are most often organised here.

Bolesławiec and the lower reaches among the forests

Below Lwówek Śląski the Bóbr flattens out and flows into the Lower Silesian Forest, a vast woodland complex. The current becomes calmer and the river wider. The natural end of the flagship trail is Bolesławiec, a town known the world over for its distinctive, hand-decorated Bolesławiec pottery.

Beyond it the Bóbr flows on for a long way yet - through Szprotawa, Żagań and Nowogród Bobrzański - before giving up its waters to the Oder near Krosno Odrzańskie. This lower stretch is already typically lowland and is paddled less often.

Stretches of the Bóbr trip: from Jelenia Góra to Bolesławiec

The Bóbr is best explored in stretches. The upper stretch, from Jelenia Góra through the Modre and Pilchowickie lakes, is the most mountainous and ends at the dam in Pilchowice, from below which the kayaks are carried overland to Nielestno. From Nielestno, through Wleń to Lwówek Śląski, begins the most beautiful and easiest part - the picturesque Bóbr valley below Lenno castle. The lower stretch, from Lwówek Śląski to Bolesławiec, is already calmer and leads through the Lower Silesian Forest. You can see every stretch on the map below - in "Take it easy" mode, with facilities and water levels along the way.

Obstacles and portages on the Bóbr

The Bóbr is sometimes called a demanding river, and that is mainly down to logistics. Along its course there are many dams, hydro plants and weirs where the kayak has to be carried overland - the main barrages stand at Wrzeszczyn and Bobrowice. The Pilchowice dam has to be treated separately: you may not come closer than 200 metres to the crest, and the portage down the right bank is steep and about 800 metres long, so the sources don't recommend it. Instead the kayaks are carried overland below the dam. That is why many kayakers begin the trip only at Nielestno - the traditional starting point, below the dam and below the weirs of the upper reaches. In the upper reaches, above Jelenia Góra, there are drops and mountain-style rapids on top of that.

Much also depends on the water level. The best time is spring, when meltwater comes down from the Krkonoše, and rainy spells in summer; at low water the mountain stretch can be too shallow. Before you set off it is worth checking the current water level at the nearby gauges. The Nysa Kłodzka, further east, with its Bardo gorge, has a quite different, much harder character.
