The Gulf of Tonkin

The Gulf of Tonkin, located between the northern coast of Vietnam and southern China. While it is economically important to Vietnam, it is also the location of the spectacular UNESCO World Heritage site of Halong Bay and its world-famous karst landscape.



The Gulf of Tonkin is located in the Southeast Asia Sea (South China Sea), an important economic gateway for merchant ships.

The gulf is 500 kilometres long, 250 kilometres wide and up to 70 metres deep in places. The Red River flows into the Gulf, and the main Vietnamese ports of Ben Thuy and Hai Phong are situated there.


Spectacular Bays

As well as being the locale for many conflicts, Gulf of Tonkin is also the location of spectacular Halong Bay, Bai Tu Long Bay and Lan Ha Bay.

Positioned 170km east of Hanoi, Halong Bay and covers an area of around 1553km2 in the Gulf of Tonkin. It belongs to Halong City administration in the Quang Ninh province, in the north-west. Bai Tu Long Bay lies to the north-east and Lan Ha Bay are in the south-west.

The UNESCO World Heritage inscribed site of Halong Bay was first recognised in 1994 and again in 2000. Famous for its stunning landscape of 1969 majestic limestone pillars, islands and islets, Halong Bay also houses mysterious caves, caverns and grottoes, all waiting to be explored by travellers to the area.
