Abstract: Community-based tourism is not only a tourism industry that aims to bring maximum profits to investors. Instead, it pays more attention to the impact of tourism on communities and environmental resources. Agrotourism has become an inevitable trend worldwide and is regarded as a potential gold mine for the development of tourism in southern Vietnam. Sơn Islet has initially been the residence of a few gardening and cage fish farming families. Until recently, the residents of the small island began to develop one of the earliest and most popular community-based agrotourism models in Cần Thơ City. As an emerging type of tourism that has recently grown in Vietnam, agrotourism has not yet considered much by researchers, and there are few studies on agrotourism, or only economic impact has been mentioned. This article aims to learn more about the overall effect of agrotourism on local communities in order to have some recommendations on making community-based agrotourism more effective. Qualitative research with observations and 22 in-depth interviews have been conducted to collect research data. This article discusses both the positive and negative effects of agrotourism on local communities. The elements of success have also been observed, and some suggestions have been made to develop agrotourism, maintain the success of this community model based on agrotourism on Sơn Islet, and achieve breakthrough growth in the near future.
