Abstract The Ida-Outanane hinterland of Agadir, in the Western High Atlas, harbours remarkable geodiversity – karst caves, travertine waterfalls, paleontological sites and tectonic structures – which has so far received little systematic documentation. This study presents an inventory and quantitative assessment of ten geosites using Brilha’s (2016) methodology, analysed according to four criteria: scientific value (SV), educational potential (PUE), tourism potential (PUT) and risk of degradation (RD). The results indicate high to very high scientific values (average 3.51), with the Win Timdwin cave leading the way (SV = 3.8), followed by the Alma Ammonites and the Imouzzer Idaoutanane Fault (SV =3.7). The educational potential (PUE = 3.52) and tourism potential (PUT = 3.415)confirm the multifaceted value of these sites. However, the risk of degradation(average RD = 2.1) remains a cause for concern, particularly for the MoulayAbd Allah Dam (RD = 2.5) and the Alma Ammonites (RD = 2.45), due to theiraccessibility and the lack of appropriate protective measures. A 224 km georoute over three days is proposed tostructure sustainable geotourism combining heritage promotion andthe involvement of local communities, thereby contributing tonational and international geoconservation initiatives. thereby contributing to initiatives of national and geoheritage importance. This study constitutes the first quantitative inventory of geosites in the hinterland of Agadir Ida Outanane, a region where only descriptive or purely geological studies existed previously.
