If Mongolia's yin is its pristine countryside, then Ulaanbaatar (UB) conforms nicely to its yang. An enormous city of pulsating commerce, wild traffic, sinful nightlife and bohemian counter-culture, the Mongolian capital elicits as much shock as it does excitement. The contrasts within the city can be exasperating too: Armani-suited businessmen rub shoulders with mohawked punks and del-clad nomads fresh off the steppes. One minute you're dodging the path of a Hummer H2 and the next you're mystified by groaning Buddhist monks at Gandan Khiid. It's a wild place that bursts into life after slumbering through a long winder. This chaotic capital is not the easiest city to navigate, but with a little patience, traveller5s can take care of all their logistical needs, watch teaditional theatre, sample international cruisine and party till three in the morning. This ever-changing city may be the biggest suprise of your Mongolian adventure.
