The Garhwal Himalaya has numerous geographical and geomorphological features (geo-sites) that can be developed for promoting geo-tourism. This study aims to examine the potential of geo-tourism in the Garhwal Himalaya and its role in fostering rural sustainability. The region has an agricultural economy with low output; however, a large number of people are engaged in traditional farming practices. Meanwhile, the development of geo-sites can enhance rural livelihoods, conserve the environment, and integrate these sites into educational curricula. This study is empirical in nature, employing a qualitative approach. In addition, the observation method was properly used to identify the geo-sites of the region through extensive field visits conducted by the author. All geo-sites were listed, mapped, and explained. These geo-sites are distributed throughout the region, though they are more concentrated in three districts – Uttarkashi, Rudraprayag, and Chamoli – mainly situated near highland sacred sites. The study suggests that the sustainable development of geo-sites can increase income, improve livelihoods, and provide valuable educational resources. It further recommends that suitable policy measures involving local communities and policymakers can pave the way for sustainable geo-tourism.
