yes, you are right.the highest cable car for snow mountain is still on construction. there are total three cable car, so you also can choose one of others two to visit. the lowest one is 3200m to Yunshan Meadow, other one is 3700m(Yak Meadown). when you go there to visit, you needn't special snow boots, because you will not walk on much snow. for the Yak Meadow, if you walk all around the meadow costs about 2~3hours. For Yunnan Meadow will be less.hope this is helpful for you!
