Southeast Chongqing, as an ethnic minority gathering area in China, boasts rich traditional village resources with great potential and value for tourism development. Taking 75 traditional villages in Southeast Chongqing as the research objects, this study systematically explores the spatial patterns, accessibility characteristics, and tourism development strategies of traditional villages by using methods such as the nearest neighbor index, kernel density analysis, buffer analysis, and overlay analysis. The results show that the traditional villages in Southeast Chongqing are unevenly distributed among counties. Two high-density agglomeration areas are mainly formed in the Apeng River Basin in the northwest of Youyang County and the You River Basin at the junction of Youyang County and Xiushan County, and a sub-high-density distribution area is formed in the southwest of Xiushan County. The overall spatial location conditions of traditional villages are relatively weak, and most of them are located far from major transportation nodes and trunk lines such as airports, railway stations, and expressways. The spatial distribution of traditional villages in Southeast Chongqing highly overlaps with cultural and tourism resources such as scenic spots and intangible cultural heritages, which provides good resource support for the tourism development of traditional villages. Considering that some traditional villages have significant spatial correlations with ecological resources such as nature reserves, water systems, and altitudes, it is recommended to explore an ecological tourism development model of “traditional villages+ecological resources” in tourism development strategies to promote the combination of traditional village protection and sustainable utilization.
