As the largest seaport in Vietnam’s northern region, Hai Phong city boasts huge potential for tourism development, especially sea-based tourism. Featuring a coastline of 125 km with more than 400 islands and islets, Hai Phong boats its potential for developing sea-based tourism which contributes over 42 percent to the sector’s revenue annually. Locally, Do Son and Cat Ba are the two major attractions in its tourism development plan. Of the two, Cat Ba, a world biosphere reserve, has much room for investment. According to Hai Phong’s department of tourism, Cat Ba island has become a more and more popular destination of many tourists, attracting one third of tourists to the city. Catching the rising demand, local tourist agents have been paying attention to developing unique products. The city approved a resolution on tourism development in 2017-2020, with a vision to 2030. Accordingly, the city will direct its resources into turning tourism into its spearhead economic sector and attract investment in sea tourism, along with other types such as ecotourism, spiritual, community-based, entertainment and resort tourism.
