How can I get to Xiamen City if I took HSR and alight at the North Station?

You must refer to how to get from the north railway station to Ximen downtown area near the city center, right?

If so, you can take the bus No. 957 from the north train station to Sibei Gongjiaochang, which is near the Zhongshan Road. Zhongshan Road is located in the city center, it is one of the most prosperous street, where you can find accommodation and eating places easily.

By the way, the bus ride is about 1 hour.

Thank you Linda.

BTW, do you have any suggestions about the nearby sight seeing points of the North HSR station besides TuLou??
Thank you!

The Dongshan Island around 160km away is a good choice, but no train leads there. At local Hubinnan or Xinglin Long-distance Bus Station, you can take a direct bus to Dongshan County first. Then take a taxi to the island in 10min. Have fun there!
