GeoTour Calw

On this circular hike, we will learn about the [GeoTour Calw](https://www.calw.de/Geotour) under the title "Where water turns into stone." Explore – discover – experience: Fancy a concentrated dose of geological knowledge? An extraordinary journey through 500 million years of Earth's history begins between Calw and Stammheim. Are there really desert and sea beds in the Nagold Valley? What effects do the different rock strata have on the flora and fauna and on us humans? Over a distance of 5.1 km, our Black Forest guide will explain incredible phenomena about the species-rich flora and fauna of the Nagold Valley in a clear and understandable way. **Registration with Black Forest guide, moor guide, and climate ambassador Nicolai Stotz (phone 0172 7385885, email hallo@schwarzwald-guides.de) is required!**
