Zbojnícky Castle's ruins were once a castle that guarded the region's salt mines. Its name "zbojnícky" from the word "zbojník" comes from times when the castle was inhabited by bandits. Although there's little to nothing left of the castle, its surrounding nature makes for a nice hike. The marked trail starts in the village Ruská Nová Ves below.
