Geology and landscape constitute a form of natural area tourism known as geotourism. Features of this form of tourism include cave, rock shelter, waterfall, among others. Geotourism attractions are visited because of their scenic geological formation, unmodified vegetation, water resources, among others; and are developed due to their valued contributions to community development, income generation and employment opportunities. Mmaku and Achi on Nsukka-Okigwe Cuesta are endowed with caves and rock shelters that can be harnessed for geotourism. This paper is aimed at examining the potentials of caves and rock shelters in the study areas with a view to harnessing them for geotourism. The study uses ethnographic research instruments to elicit useful information and data collected were analyzed descriptively. The study argues that Mmaku and Achi communities' Standard of living can be enhanced if these natural resources are harnessed for geotourism.
