The Hoczewka river – the Bieszczady river, which runs from Jabłonki to Hoczew where it falls into the San river. In Hoczew its bed is crossed by the rocky thresholds. The riversides are built here with Carpathian sand stone whose layers go perpendicularly in the race of river. The rocky thresholds in Hoczewka are one of the nature monuments in the Bieszczady mountains.
