Jerzwałd is home to the Zespół Parków Krajobrazowych Pojezierza Iławskiego i Wzgórz Dylewskich (Iława Lake District and Dylewo Hills Landscape Parks Authority). The Iława Lake District Landscape Park, established in 1993, covers more than 25,000 hectares, and around half of its waters belong to the Jeziorak complex – Jeziorak being the longest lake in Poland at 27.5 km. We created an audio guide in the form of a mobile app that takes visitors around the educational exhibition at the park authority's headquarters. The recordings introduce the nature and landscape of the region, and the exhibition can be visited at your own pace. The audio guide is available in Polish, English and German.
