50 kilometres (31,07 miles) towards South of Ölgii, in the centre of the province of Bayan-Ölgii, there is Tolbo Lake, ”stain lake”. It extends on 185 square kilometres (71,43 miles) in the heart of the Altai range, at more than 2000 metres (1,24 mile) above the sea level. Tolbo Lake’s water is particularly clear. The road that leads there passes along glaciers and, in Winter, it’s possible to move on the iced lake.
The lake was the witness of the battle of Tolbo lake (1921) during the Russian civil war, when the Bolsheviks allied to the Mongolians defeated a White Russians army. You can spot by the lake a couple of memorial plaques.
