Daily guided hike | Start at 10:30 am
Walk between steep rock walls, experience rushing waterfalls, and discover vividly coloured rock layers. Our guided adventure tour through the Bletterbach Gorge takes you right into millions of years of Earth’s history.
In the narrow section of the porphyry gorge, impressive rock formations, sandstone layers, and a unique natural landscape in the UNESCO World Heritage Dolomites await you. Together, we set out in search of traces from the past: plant fossils, fossilised dinosaur tracks, and fascinating mineral deposits make the history of our planet tangible and easy to understand.
Shared discovery and experience are at the heart of this tour. Our trained guides present geology and Earth’s history in a clear and engaging way, while also sharing interesting insights about the region and the people of Aldein.
