||Barguzinsky Nature Biosphere Reserve is the first protected area in Russia, most of human activities are strictly forbidden here. Established on the northeastern shore of Lake Baikal in 1916, it has gone through functional and territorial changes. During the past decade, educational tourism has become a priority. After historical and geographical analysis of conservation efforts, this function can be justified in certain areas. The research goal is to demonstrate tourism possibilities from perspectives of long-term management. Objectives are analysis of territorial changes, mapping of infrastructure and routes, assessment of visitor preference, justification of new recreational sites. We used the map and results of 1914-15 Doppelmayer Expedition as the basis because they contained original assessments of cultural and biological resources, full area description, materials on reserve foundation and infrastructure distribution. We analyzed five stages of boarder changes in 1916, 1937, 1951, 1957 and 1987, reserve visitation during the Soviet period and recent years. Next, we created an integrated map of infrastructure by overlapping modern maps with the Doppelmayer’s map. Thus, coastal educational tourism sites received full description including primary vegetation, forest vegetation of Barguzinsky ridge, original toponymical names and cultural constructions. Davsha Bay could become the main educational tourism center, despite of boarder changes it had always been a part of the reserve. Tourists had visited the area since 1970s, recently their annual number reached approximately 500. Two proposed trails here were a part of a historical route; their creation would have both environmental and historical meanings. Assessment of anthropogenic load over past decades allowed constructions additional trails and demonstration sites and reconstructions of traditional housing. Deep analysis of historical and geographical features supported educational tourism development by determination of priority sites and provision of supplementary information. Centennial management of Barguzinsky Nature Reserve showed possibilities for educational tourism in certain areas.
