Hi, what is the best way to happy valley if you are coming from Hong Kong ?

It is suggested to take the East Rail Line to reach Lo Wu Station. Then you need to pass the border to reach Luohu District in SZ. Upon reaching SZ, you can find the Luohu Subway Station, where you can take the Luobao Line to reach Window of World Station. Get out of the station, you can easily find the park directly.
