I have been shown www.mapbar.com for the Kunming bus routes, but does anyone know if there is a place to view the bus routes in English? Thanks!

maps.google.com

Just beware that some of the bus stop names and sometimes even bus numbers/routes are not up-to-date on maps.google.com, so you may end up at a bus stop without a clue how to get to the desired destination. Happened to me quite a few times. For more up-to-date information look at Baidu...but it's in Chinese.
