This paper aims to shed light on the significant contribution of tourism development in the geopark area, particularly through the concept of geotourism. The Ranah Minang Silokek geopark area in Sijunjung Regency is a treasure trove of attractions and developed destinations in geodiversity, biodiversity, and cultural diversity. While tourism, in general, can foster a sustainable life, cultural tourism, and cultural heritage can have a significant positive and negative impact on people's lives. Therefore, it is crucial to understand the extent of the contribution of sustainable tourism development through geotourism in Silokek Geopark. This research, conducted through qualitative methods and a narrative approach, aims to develop the objects in Silokek as geotourism based on sustainable tourism development. Data collection was carried out through interviews with management and the observation of geological objects and FGDs with stakeholders. Data analysis was done through a Stepwise Forward approach. The findings reveal that the development of geotourism can have a profound positive impact, not only supporting economic growth for the local community and government but also serving as a foundation for efforts to preserve and protect landscapes and geology, the main essence of the Silokek geopark. This research aims to shift the perspective that geotourism is the antithesis of mass tourism, and instead, highlight its contribution to the principles of geoparks (Unesco Global Geoparks Network).
