Ulaanbaatar is located on the bank of the Tuul River and surrounded by four sacred mountains with dense pine forests on the northern slopes and grassy steppes on the south. Mostly described, as sunny, peaceful and open, Ulaanbaatar is a city of contrast where modern life comfortably blends with Mongolian traditional lifestyle. Wide streets are flocked by modern cars, while horsemen and cattle are still common scene. Though modern buildings characterize the city center, visitors arriving either from the Buyant-Uhaa airport or by train to the main railway would not fail to notice thousands of traditional Mongolian "Gers" in the vicinity, an area referred to by locals as "ger district".
