Supported by a sophisticated cross-boundary transport network, many Hong Kong residents are choosing to travel to cities in the Greater Bay Area. Shenzhen, Guangzhou and Zhuhai ranked the top three cities among the 10 destinations Hong Kong travelers are most willing to visit. Foshan, grabbed sixth spot.

Other popular mainland destinations include Shanghai, Beijing, which ranked fourth and fifth, respectively, as well as Chengdu, Hangzhou, Changsha and Sanya, who were also on the top 10 list.

As this year’s Easter holiday overlaps with the Qingming festival, or the tomb-sweeping holiday, which together form a long break of five days from April 3 to 7, outbound tourism in Hong Kong is also expected to grow.

A report from online travel agency Trip.com shows that Hong Kong’s outbound bookings increased by 50 percent on a yearly basis.
