Bayan Nur (prefecture)
There are flights that leave from Beijing (PEK) several days a week at 7:30 am, and arrive at around 10:00 am at the Bayan Nur Airport (RLK). The airport is about half an hour outside of the city by taxi.
Unless you are coming from the airport, most things are within in a two hour walk in the old city of Bayan Nur, Lin He. Taxis are very cheap and can get you to anywhere in the city for often less than 10 RMB
You can travel to other cities in Inner Mongolia by long distance bus. Cities like Baotou and Ordos are two or three hours away if you take the highway. A train to Hohhot takes about 4 hours from Bayan Nur.
