The Rieca stream, flowing from northeast to southwest starting in Luico (Slovenia) and joining the Alberone stream near Savogna, has carved a spectacular gorge in the carbonate rock over many millennia, downstream from the village of Cepletischis. A prime observation point of this geomorphological phenomenon is the bridge on the road descending from Cepletischis to Grimacco. At this point, the gorge is very narrow (just a few meters wide) and about 12 meters deep.
You can descend to the stream via a path that branches off the road near the bridge and quickly leads to the water. The overhanging rock walls sculpted by the stream, combined with the shade and coolness of the area, give the Rieca gorge high naturalistic and landscape value. The vegetation has adapted to these specific climatic conditions, forming a characteristic gorge forest, dominated by hornbeam, followed by wild lime and mountain elm. The undergrowth, rich in geophytes, boasts numerous ferns, notably the hart's tongue fern.
Cepletischis was once the only village reached by a paved road, built by soldiers during World War I. It had three fountains, a dairy farm, and several mills, one of which is now restored and open to visitors.
