Bletterbach

Bearing in mind the enormous geological importance of the Bletterbach system, the Municipality of Aldino/Aldein created the Bletterbach Geoparc, a geological park within a natural monument.

There are no refuges in this system.

The Bletterbach system, covering just 271 hectares within the Province of Bolzano/Bozen, is the smallest of the UNESCO Dolomite systems. This natural monument is a narrow gorge running through the territory of the Municipalityof Aldino/Aldein, Monte Pausabella/Schönrast and Passo degli Oclini/Jochgrimm. Geographically separated from the other Dolomite chains, it is dominated by the summit of Corno Bianco/Weisshorn (2,317m). The enchanting landscape of the Bletterbach system is also a geological treasure-trove. The gorge was formed by the Bletterbach mountain stream eroding the rock formations of volcanic origin found in this area. The canyon narrows from a width of 200-300 meters at the top to 20-30 meters at its bottom and it is over 400 meters deep. The riverbed is punctuated in at least four places by spectacular waterfalls of dozens of meters in height. The upper part of the gorge opens up into a basin, 600-700m in diameter, over which the Corno Bianco/Weisshorn looms in all the immaculate glory of its white Dolomite rock. The 900m gradient between the Corno Bianco/Weisshorn peak and the bottom of the Bletterbach gorge is a journey in time, through the history of our planet. No other place in the Alps or Dolomites has such perfectly preserved rock strata visible to the naked eye, demonstrating in minute detail how the Dolomites were transformed in the time between the Early Permian Era and the extinction event of the Late Permian/Triassic Era.

Protecting the environment

Bearing in mind the enormous geological importance of the Bletterbach system, the Municipality of Aldino/Aldein created the Bletterbach Geoparc, stretching from Aldino/Aldein to Redagno/Radein, a geological park within a natural monument. The Geoparc is well equipped for educational activities and excursions, allowing visitors a hand-on experience of the processes that went into forming the Earth and the Dolomites in particular, and how life evolved therein. Among the excursions in the Geoparc are a geological trail, leading visitors to the very heart of the canyon, and a woodland path that is also suitable for pushchairs and wheelchairs. Along both routes there are plenty of information boards on the geological history and the flora and fauna of the Bletterbach. Next to the Geoparc there is Parco Naturale del Monte Corno/Naturpark Trudner Horn, a natural parkland covering some 6,800 hectares spread over the Municipalities of Anterivo/Altrei, Egna/Neumarkt, Montagna/Montan, Salorno/Salurn and Trodena nel parco naturale/Truden im Naturpark (www.bletterbach.info).
