7. A'er Mountain, Inner Mongolia Autonomous Region

Do you know where China's smallest city is? It is A'er Mountain where you could enjoy the beauty of four seasons. Located at the foot of southwest Daxing'anling Mountains in North China's Inner Mongolia Autonomous Region, A'er Mountain is famous for its mineral springs, abundant volcanic lakes, and beautiful forest. A'er Mountain means 'hot magic spring'.

Standing on the borderline between Mongolia and China, you could see the road and mountains in Mongolia, enjoy volcanoes and the lake around, and have the opportunity to see a "snow cloud" when you have the sun over your head but a cloud is snowing nearby.

The peak season for A'er Mountain is July to September. However, the four seasons at A'er Mountain have their unique beauty waiting for tourists to discover it. There are now direct flights from Beijing.
