Visited the Kunming Waterfall Park yesterday and was fairly impressed-beautiful views, clean & upkept grounds, lots to see & people watch. Update from the earlier gokunming article profile: the viewing bridge and path behind the waterfall are both now open and definitely enhance the experience. Bring an umbrella unless you want to get soaked going behind the waterfall.
To get there, I took metro line 2 to 司家营 and bus #Z65 to 天宇澜山小区. The 司家营 bus stop is almost directly outside exit B.
Tip: the #Z65 bus runs in a loop to and from the waterfall park, so on the return trip you'll catch the same Z65 bus at the same stops you departed from. Make sure the return bus shows that it's headed back to 司家营 (the characters will show on the ticker outside the bus, or you can ask)；occasionally a Z65 bus will drive a different return route through residential.
