Abstract: Enshi is a mountainous ethnic tourist area with rich resources. In recent years, the promotion of pro-poor tourism policies has provided new opportunities for the development of the tourist industry of Enshi. A proper understanding of the size, direction and mode of tourist flows in this area is of great significance for government and tourism enterprises to make scientific decisions and rational plans. Drawing on the information offered by online travel notes, this paper investigates the spatial network structure and the transportation mode of the tourist flows in Enshi using social network analysis and ArcGIS spatial analysis. The results reveal: (1) The network structure of the tourist flows in Enshi is dispersed with a rather weak mobility of tourists between various tourism nodes. （2) Enshi, Lichuan and Hefeng are three tourist transportation hubs in the area, and the Enshi Grand Canyon is the assembling center of the network of tourism flows in this area. (3) The Enshi Grand Canyon, the Tusi City, the Tujia Girls’ town and the center of Enshi City are four core nodes, which are well connected with each other, of the tourism flows in Enshi. （4) There exist obvious seasonal variations in the tourist flows of Enshi, with the major flows concentrated in summer and autumn. (5) Bus and self-driving are the major transportation modes of tourist flows in Enshi. The tourist traffic lines are well developed in the area, but the public transportation system is still unable to satisfy tourists’ demands. （6) The character of mismatch of supply and demand has been found. The spatial mobility of tourists is rarely influenced by the level of tourism nodes.
