Geological nature trails provide a wonderful opportunity for young and old alike to learn about stones, rocks and one million years of geological history. With a wide variety of typical rocks and depictions of how they were used the geological nature trail, Geologische Lehrpfad Hochstetten-Dhaun, illustrates individual periods of geological history in this region. The Geologische Lehrpfad Gemünden, another geological nature trail, also highlights geological history. Rock groupings line a four-kilometre path, each with a plate explaining name, origin, formation, specificity and age of the rocks. Living geological history can also be experienced along the one kilometre Geopark Krahloch with 14 explanatory stations.
