Geotourism is one of the fastest growing tourism branches. Geoparks feature prominently in geotourism as well as geoeducation. Well-designed geotrails link local geology, geoheritage and geoeducation. Unfortunately many trails do not consider or insufficiently acknowledge recent didactic and touristic findings. As a result, they fail to interest a lay audience in geological phenomena, convey relevant information, and attract tourists to the region. A catalogue of state-of-the-art criteria for the evaluation of existing geotrails based on a case study of the UNESCO Global Geopark Swabian Alb (Germany) was elaborated by a comprehensive literature research and subsequently verified on the basis of selected model trails. Finally, recommendations for model geotrails were derived. The term “model” refers in this case to aspects of geoeducation as well as geotourism. Results showed considerable enhancements, but also the further necessity of improvements such as a stronger consideration of Education for sustainable Development (ESD), a better integration of the criteria of geo-interpretation as well as the opportunities and potentials offered by the to-date too scarcely used new technologies. Our surveys in the UGGp Swabian Alb largely coincide with the results of national and international research. Often it is merely small factors that differentiate an adequate and a model geotrail. Our checklist of criteria offers a good basis for these factors.
