Guided hike on the saurian trail every Saturday at 2:30 p.m.
The Saurian Trail takes you on a journey to the Permian, about 260 million years ago, a time during which the rocks and fossils of the Bletterbach Gorge and the Dolomites were formed.
Families with children, senior citizens, individuals with disabilities, people out for an easy stroll, and also more adventurous hikers are invited to explore these footprints from the dim recesses of time and learn more about the creatures which created them.
They can compare ancient plants with modern-day species, and even study micro-fossils.

Orchid hiking tour
“Some are small and inconspicuous, while others are brightly colored or have a captivating fragrance: the many protected plants and special flowers that can be found in and around the GEOPARC Bletterbach. Wild orchids like the elegant lady’s slipper and the diverse spotted orchids, the fiery fire lily and the tall Turk’s cap lily, gentian, cotton grass, and sundew – those who look closely can discover a surprising variety of endangered plants. On our hikes under the motto ‘What’s blooming there?’ our GEOPARC guides make sure that none of these rarities go unnoticed and know many special stories to tell about each unique plant.”

My personal tour
The next family outing should be something special? A day that children and their parents, grandma and grandpa, aunts and uncles will remember for a long time?

Then take the opportunity to book your very own GEOPARC guide for your private tour. You are among yourself, so we can specifically address your wishes: What do you really want to see? Which topics are of particular interest to you? How long should the tour last? Do the children need an incentive to explore the gorge?

This offer is of course not only for families, but also for you and your partner, your friends, your employees …

For your personal tour you can contact us here.

Outlook into the past
After the musical opening of a very special evening in the GEOPARC Bletterbach, we will walk to the panoramic point above the Visitors Centre. There, we however won’t call your attention to the deep gorge, but invite you to look at the dark sky: thanks to two telescopes you will see the planets Saturn and Jupiter as well as some of the most beautiful constellations… and maybe – with a bit of luck – also some falling stars.
The astronomer David Gruber and the geologist Benno Baumgartner from the Nature Museum South Tyrol will explain you the origins, the characteristics and the particularities of stars and planets.

Start 9 pm from the Visitor Centre.

Scientific Excursion with the Director Hannah Pomella
During this guided excursion, geologist and Director of GEOPARC Bletterbach, Hannah Pomella, leads you through the impressive gorge in the southern part of South Tyrol, between Aldino and Redagno. She explains why this place is of great importance to the international scientific community and offers insights into her work within the UNESCO World Heritage Dolomites.

In a clear and accessible way, she shows how researchers use rock layers and fossils to reconstruct the history of the Earth and its climate hundreds of millions of years ago and why this knowledge is still highly relevant today.

Hannah Pomella has been Director of GEOPARC Bletterbach since 2025. Previously, she was Associate Professor of Geology at the University of Innsbruck. For more than 20 years, she has focused on the formation of the Alps, with special attention to the geology of South Tyrol.
