The Equator Pasaman Geopark area, with its natural beauty and cultural diversity, is a potential destination to be developed. Equator Pasaman Geopark is a geopark located in West Sumatra, Indonesia, which combines geological, biological, and cultural diversity. In addition to being an attractive tourist destination, this geopark also plays a role in the preservation of nature and culture, as well as sustainable local economic development. The uniqueness of the geopark, such as its location on the equator line, national history with the figure of Tuanku Imam Bonjol, and biodiversity, make it a valuable asset for tourism promotion and environmental education. Service activities were carried out at the National Cross Tourism Competition (LAWNAS). The purpose of this community service activity is the promotion of geoparks, environmental promotion, cultural preservation, local economic development, increasing tourism, and external party partnerships. The research method is to identify service to the integrated tourism system, then organize competitions, as well as promotion and marketing of geotourism and finally environmental education and conservation. The parties involved in this activity include local governments, communities, and community service teams. The results of this community service activity show that all contribute and are actively involved in this activity, thus making a positive contribution to the development of local tourism
