The bay, twice recognised by the UNESCO for its landscapes and geological values, is in Group G, which includes sea landscapes and beaches.

In the voting launched by NOW at the website http://www.New7wonders.com, a total of 260 national and international sites are divided into seven groups from A to G. The voting is divided into three phases.

Twenty-eight finalists will be announced by the organisers on July 21 at the NOW headquarters in Zurich, Switzerland.
Later, the campaign will continue to vote for New Seven Wonders of Nature, which will be unveiled in 2011.

During the first phase of the campaign, which took place between July 2007 and December 2008, three of Vietnam’s famous tourist attractions were nominated, including Halong Bay, Phong Nha-Ke Bang National Park and Mount Fansipan.
