From Pingyao to Mt. Mianshan

If you want to take the high-speed train to Jiexiu, you need to go to the Pingyao Gucheng Railway Station, which is quite far from the ancient town. So I suggest you take the normal speed train from Pingyao Railway Station, which is just walk distance from the north entrance of the ancient town.
The train ride is about 25 minutes, so it would be a good choice. Upon arrival in Jiexiu, you can hire a taxi to the Mianshan Scenic area, and the fare would be CNY50 – 60.
