On the road between Ulaanbaatar and Tsetserleg, near the border with Bulgan aimag, the lake Ugii Nuur is a wonderful place for birdlife – cranes and ducks, to name just few species, migrate to the area around late April.
The lake is also renowned for its fishing (and the bugs by the lake shore!). The lake and Khar balgas ruins can only be reached from the direct road linking Tsetserleg with Ulaanbaatar.
