The formation of a competitive tourist space in the Arctic regions is expedient from the standpoint of diversification of predominantly single-industry local economies and increasing the socio-economic sustainability of local communities. However, it is extremely important that the measures aimed at achieving these effects are correlated with the ecological and social context of the territories and, fully using their existing potential, do not lead to an aggravation of ecological and economic risks. The purpose of this work was to assess the prerequisites for the development of eco-tourism in the example of the Arctic region and economically related territories and consider the possibilities of forming ecotourism zones. Based on statistical data, cartographic materials, and content analysis of semi-formalized interviews of experts, this work investigated the current level of socio-economic development of the Karelian Arctic, the existing tourist infrastructure, natural, and cultural-historical objects. Strengths and constraints of eco-tourism development are emphasized. A number of innovative tools and approaches for the development of ecological tourism in the Karelian Arctic were proposed, the introduction of which will increase the tourist attractiveness of the territory, and ensure its sustainable development by reducing negative environmental impacts and depopulation.
