To reach a broader public of people interested in geosites and human-environment interactions, the authors here add a geoguide about this mountain district in Ethiopia(13°30’ N, 39°10’ E; upto 2850 m high) which shows a varied lithology. A large team has carried out research in that district over the past 23 years, including long stays in the areas. Numerous viewpoints and geosites are only accessible on foot; hence the authors prepared the book as a trekking guide, which will enhance sustainable tourism in the same time. This edited work summarises the study results in the international literature into a comprehensive book, which comprises 35 thematic chapters, detailed description of 573 km of trekking routes to access the landscape and the most scenic excursion points, as well as the necessary logistical information. A state-of-the-art trekking map is included as a digital annex.
