Kunming Travel Guide

Known in China as the City of Eternal Spring, Kunming is at an almost-tropical latitude but 2000 m (6600 ft) altitude which gives it a very temperate climate. The air is also quite clean compared to other Chinese cities, even though the traffic congested streets still emit more than their fair share of pollution. However temperate it may be, in winter it has been known to snow, so if visiting in December-February, pack warm. When it rains - it's cold. In addition to its own charms it serves as a hub from which to explore Yunnan province. If you do not have a lot of patience with miscommunications then it's best to have a translator. The city has a population of around 3 million, the prefecture near 6 million. Both are growing fairly rapidly; the prefecture is predicted to hit 10 million by 2010.
