Go Zhuhai By Boat

 From Hong Kong: There are several ferries per day from Hong Kong International Airport, HK-Macau Ferry Terminal (港澳碼頭;  Hong Kong/Hong Kong Island), China Ferry Terminal (中港城碼頭; Kowloon) and Shekou Ferry Terminal (蛇口港; Shekou) arriving at the Zhuhai Jiuzhou Ferry Terminal (九洲港). There is a taxi rank and bus stops directly outside. You can take a free bus ride to GongBei by showing your ferry ticket. Visas can be purchased here for most nationalities (not American citizens). Payment is in RMB only and the ATMs are through immigration so plan ahead.

The HKIA-Zhuhai ferry is operated by Chu Kong [10], who charge HK$260/¥280 one-way to/from Zhuhai.

Getting to Zhuhai Airport from the Jiuzhou Ferry port that connects Zhuhai with Hong Kong, an Airport bus can be taken for about ¥30 and the last bus departs at 8PM. The journey takes about 2 hours.

From Macau: There is a ferry service operating from Macau's Inner Harbour's Pier 14 (澳門粵通碼頭) to Wanzai. Daily departures roughly hourly from 8am to 4pm.
