What is the best way for a day trip from Hong Kong to windows of the world?

1. You can easily have a round-trip between Hong Kong and SZ. You can pass the custom from Luhohu Port. Then take subway Luobao Line to WOW Metro Station, Exit I. After arriving, walk south 250 yards (230 meters) to find the destination. The return way is the same.

2. Although you are eligible to apply for VOA at Luohu Port, there is no guarantee that you can get it successfully. Thus you are suggested to apply for it in advance in your country.
