"Olzy" Nature Reserve, Rudawka Rymanowska

The "Olzy" Nature Reserve is the youngest inanimate nature reserve in the Podkarpackie Voivodeship, protecting a unique geological formation in the Wisłok river valley.

Established on August 10, 2022, the reserve covers an area of 41.45 hectares in the Zarszyn municipality, near Rudawka Rymanowska.

The primary subject of protection is the so-called Olza Wall (Ściana Olzy)—the largest exposure of menilite shales in the Polish Carpathians, exceeding 30 meters in height, formed by the river's vertical erosion. This area is a fragment of the Carpathian flysch and preserves the natural character of a gorge landscape, complemented by a Carpathian beech forest stand.
