The development of tourist communication of the five Caspian region countries is considered one of the most relevant in the region's strategic aspects of economic development. This article deals with tourist resources and what functional mechanisms will develop tourism in the region. The article offers an overview of the state of tourism infrastructure of Russia, Azerbaijan, Kazakhstan, Turkmenistan, and Iran over the past five years. The prospects of cruise tourism cooperation are considered. Opportunities for the development of cross-border tourism are analysed. The article raises the problems of ecology in the Caspian region, which is also a factor in the development of the tourist sphere.
