The Pieprzowe Mountains being as old as around 500 million years owe their name to the colour of their rocks [“pieprzowe” meaning “pepper” in Polish]. The so-called argillaceous schist oxidised under the influence of atmospheric conditions and then crumbled to resemble pepper.
Now they constitute a unique on the European scale geology and nature reserve dominated by wild rose and junipers with their navy-blue berries. A beautiful view over the Vistula Valley and the Old Market located on the escarpment stretches from the reserve.
