There are also some near Qingliu Temple in Anning. Behind the Golden Temple, there are several places in Shuanglong, including Wild Duck Lake, Shaoshao, Turkuan and Baiyi.
If you want to play or go to a crowded place, you can go bungee jumping on the water near Kunming.
Anyway, bungee jumping still needs to find a place with good environment and beautiful scenery nearby.
Are you interested in going east around the city? On those bridges, the height is absolutely enough. For safety, you can find an outdoor sports club as a coach.
These places are not too far from Kunming, and the driving distance does not exceed1h. There is no through train, so you can only charter a car or take a "black face" bus.
