However, the main international airport is Chinggis Khaan International Airport, located approximately 20 km (12 mi) from downtown Ulaanbaatar.

There are paved roads from Ulaanbaatar to the Russian and Chinese borders, from Ulaanbaatar east- and westward (the so-called Millennium Road), and from Darkhan to Bulgan.
