The Fontanone Barman spring, situated on the northern side of the Musi mountain range, is a spring of Karstic origin which produces a delightful waterfall. This is the source of the Barman river, which flows along the narrow valley and, after a brief course, empties into the Resia river.
The spring can be reached via an easy forest track, ideal for young children too. Just above the spring is the Uragano cave, formed by a long underground tunnel which is the destination of many speleological expeditions.
