From the Walk, you can enjoy some glimpses of the Ravedis Dam, created to regulate the outflow of water from the Cellina stream. The catchment basin of the Cellina and Meduna is located in one of the wettest areas in Italy and this causes, especially in the autumn period, frequent flooding of the river. The history of this dam is very troubled, as the first plans for a dam near the narrows date back to the 1950s. The dam is currently still an open construction site, but visits can be arranged for small groups by contacting the Cellina-Meduna Reclamation Consortium. Going up the Cellina Valley, it is possible to discover the clear and transparent waters flowing in the Cellina Gorge, an incredible canyon formed by steep rocks that plunge vertically into the stream with crystal-clear waters, among the quiet and beauty of the Nature Reserve managed by the Friulian Dolomites Natural Park. The reserve covers the most significant part of the large incision that the Cellina stream carved in the limestone strata between Montereale and Barcis before its outlet into the upper Pordenone plain. The geomorphological aspect is typical of a large canyon, the largest in the region and undoubtedly one of the most spectacular in Italy.
