This paper aims to present results of the preliminary
detailed inventory of the geoheritage of Doukkala-Abda
region. Thirty-six geosites have been classi
strategies for the protection, the sustainable management of
the inventoried geosites and the development of proposals
for geotourist trails in the region.
The inventoried sites are classi

consideration their scienti

degree of vulnerability and the nature of conservation required,
through to proposals for various geotourist trails, in order to
offer visitors other activities in addition to enjoying the natural
and cultural heritage that exists in the vicinity of the sites.
