In the midth of a thinly populated wildness lies the foremost natural wonder - lake Baikal.It’s the oldest lake in the world - its age is about 25-30 million years.About 30 uninhabited isles are scattered throughout the lake.It’s the world's largest reservoir of drinking water.It occupies the territory of 12000 m2 and 400 km long.Most of the coastline lies in an environmentally protected area.The most numerous of the indigenous people are Buryats.A feeling of tranquillity settles over the coastal village in long summer afternoons.A vehicle driving along the village’s mainstreet is a rare sight.It lies in the border area between the Siberian forests and the grassy steppes.
