How Do I get From the Chongqing north railway station to the Yangtze river cruise pier?

You can take the local subway line 3 from the north railway station to reach Niujiaotuo Station where you can transfer to line 2 to reach Linjiangmen Station. Then hire a local taxi to reach your dock. In this way, the taxi fare is about 15RMB.

If you take a taxi directly from the north railway station to the dock, the taxi fare is around 30RMB.

How long of a drive is it to just take the Taxi from the CQ north railway station?

The taxi takes about 20 to 30 minutes.
