The World Heritage Site

The Gulf of Tonkin is a saltwater bay in between Vietnam and China, a north-west section of the East Sea and part of the Pacific Ocean, covering an area of approximately 126km². The Bay has two gates to the ocean; the main gate is in the area of Con Co Island in Quang Tri Province, Vietnam while the other is situated in China.  

The Gulf is comprised of three bays, Halong bay, Bai Tu Long Bay and Lan Ha Bay. The area characterised by thousands of limestone islands, formed by millions of years of erosion and tectonic processes creating breathtaking scenery, with beautiful caves and spectacular seascapes. Its aesthetic and geological value was recognised when Halong Bay, a part of the Gulf of Tonkin, was listed as a UNESCO World Heritage Site.

A limited area of the Gulf is open for public visit. Many areas still remain untouched, their hidden charm waiting to be explored. 

Biking on Cat Ba Island
"Cat Ba archipelago can be compared with the World Heritage Puerto-Princes Subterr anean River National Park (Philippine) and Thungyai - Huai Khaeng Wildlife Sanctuaries (Thailand)". That is how UNESCO describe the exceptional values of the site.
Breath-taking view of Lan Ha bay
Situated south of Halong Bay, Lan Ha Bay features the same beautiful limestone karsts that define its neighbours, in addition to many white sandy beaches. The Bay covers an area of more than 7,000 hectares; 5,400 of which belong to Cat Ba National Park.
Bai Tu Long Bay
Bai Tu Long Bay is located east of Halong Bay. Bai Tu Long is as beautiful as its famous neighbour but less traveled. As an off-the-beaten-track destination, Bai Tu Long Bay promises a unique experience.
Scenic beauty of Halong bay
Halong Bay, located in the Gulf of Tonkin, in the north-east of Vietnam, is about 160 km from the capital, Ha Noi. Featuring nearly 2000 islands and islets, Halong Bay covers a total area of 43,400 hectares.
