The Bletterbach gorge - Dolomites UNESCO World Heritage

The Bletterbach gorge near Aldein/Aldino

The (hi)story of the Earth

The Bletterbach stream has carved its way deep into the foot of the mighty Weisshorn peak near Aldein. Since the last Ice Age, some 18,000 years ago, great rock walls have been formed here through weathering and erosion to create the Bletterbach gorge. You can today discover, admire and hike through a huge diversity of rock colours and forms – there are even ancient plants and animals to be seen here as fossils! Guided tours, themed trails, family hikes and a forest nature trail all open the gorge, a Dolomites UNESCO World Heritage Site, to adventurers large and small. And, after exploring the gorge or climbing the Weisshorn, the nearby alpine pastures are ideal for taking a rest.
