Khuisiin Naiman Nuur literally means 8 lakes of Khuis, is the best destination for horse riding, and walking trails. The Naiman Nuur (Eight Lakes) were formed by volcanic eruptions centuries ago. The park is located at 2400 metres above sea level, between towering mountains of Khangai mountain range, the Eights Lakes are only reachable by horse or foot trekking. There are literally eight lakes in the distance of 500 m to 3 km from each other. Locals say all of them are connected underground.

The national park is located in a high mountains area comprising alpine meadows and forests of conifers (Siberian pines and Siberian larches). In the North of the protected area, we can see entire valleys strewn with volcanic stones. The peaks of the mountains are arid.

The place is very cool and there can be snowstorms in June or August. In the heart of Summer, temperatures rarely go until 20°C during the day. 400 to 500 millimetres (16 – 32 inches) of rain fall each year.
Inside the national park, we can see 50 species of birds, such as the black-throated loon, great cormorant, bar-headed goose, or whooper swan.
