Day Trip from Wroclaw to Erran Rocks "Błedne Skały": The name of a unique rock labyrinth comprising the Skalniak Ridge (915 m above sea level) carved in Upper Cretaceous sandstones by water and winds, using their uneven resistance to weathering. They are located in the Góry Stołowe National Park. The 21.14 hectares created on the area form a several hundred meter tourist route with a unique charm, which we often literally squeeze in between narrow narrow cracks.
