A kayaking trail on the Sidra river
The trail can be started from Water Sports Centre over the water reservoir, a place with a campsite, or in Siderka village, below the place where kayaks have to be carried, on 15,3 kilometre of the trail. The Sidra river can provide wonderful adventures before kayaking on the calm Biebrza river, as a tourist has to be exceptionally careful here – he or she will meet a lot of rapids. Other difficulties are low footbridges and tree boughs blocking the river or growing on its bed. Depending on the water level, it may be necessary to carry the kayaks in a number of places. If the water level is low, the 2-metre tall concrete blocks damming the river become an obstacle, while when the level is high they go unnoticed. There are also concrete valves (usually opened) with wooden pegs on the bottom, hiding behind them.
