The regional nature park of the Serrai of Sottoguda or ” Serai ” is among the beauties of the Dolomites, a two-kilometer gorge, with walls extending to some 400 meters. In some way they are not far .
The erosion of the Pettorina stream, flowing down the gorge and formed over millions of years , shaped rocks with caves and crevices. The width of horror ( in geology deep throat ) is little less than 10 meters. Streams and waterfalls – as the Pisa of Franzei – are flowing along the walls. During the Winter season, they form ice walls known and visited by mountaineers – coming from all over the world – who practice ice climbing.
