The Doberdò and Pietrarossa Lakes Nature Reserve Loop Trail

What makes the Doberdò and Pietrarossa Lakes Nature Reserve so truly remarkable is that it is characterised by two large depressions, partially filled with lakes and separated by a limestone ridge. Lake Doberdò is one of the few examples in Europe of a karstic lake-pond. Its water level changes constantly depending on the flow of the Vipacco and Isonzo rivers. Hikers will therefore have the opportunity to experience an area that features ever-changing views of the natural landscape over the course of the year, which makes it ideal for more than one visit. Along the route, it is also possible to recognise the remains of trenches dating back to the period of the Great War, which, together with the information panels along the route, will provide a unique insight into local history as well as the pleasure of walking through nature.
