The idea of a trail circumnavigating Baikal had been mentioned decades. Buryat and Irkutsk scientists, travellers, photographers dreamed of such a project. However, the project was officially presented only in 2000. From this moment, building a trail around Lake Baikal was started by volunteers from different countries. Volunteers carry out work on cleaning, marking, the building of roads, bridges and stairs. Path creation is not complete, but several routes already operate. According to the idea, the length of the trail will be about 1800 km, and it will connect three national parks and three nature reserves.
