Sidra Water Trail

Sidra River, left bank tributary of Biebrza, 32,8 km length.

The trail leads through spectacular valley 1 to 2 km wide, partially swampy, largely meliorated, used as pasture and meadow. Trail length from Sidra village Biebrza river mouth is 20 km.

The best option is to start the trail at Water Sports Center (Ośrodek Sportów Wodnych) near the bay, where a campsite exists, or in Siderka village below the portage on 15,3 km of the trail. Sidra river can be a remarkable experience before slow Biebrza trail since visitors should be very cautious here due to lots of riffles. You also have to watch out for low footbridges, tree branches and encroached river bed. There will be portages which depend on water levels. When the level is low, 2 concrete steps are an obstacle – invisible when the levels are high – and concrete floodgates (usually open) with wooden poles behind it.
