The Czarna Przemsza river flows through major cities of Zagłębie. For centuries, it has been used for water transport. Nowadays, we can encounter more and more kayakers on the river, who make use of it for recreational purposes. Kayakers can start their trips in the vicinity of the castle in Siewierz, and then cover the distance of the water reservoir of Przeczyce and Siewierz, and finally end in the picturesque area of the Będzin stronghold.
