Meanwhile, the Management Board, in collaboration with other relevantdepartments are calling on tourists, tour guides, and travel boat associationsto work together to protect the iconic islet.

All the water vehicles operating in the area of Trong Mai Islet must maintaintheir speed under 10km/h and keep a minimum distance of 70m from the islet.

The formation of Ha Long Bay dates over 500 million years and the limestonethat is found in the bay began forming around 340 million years ago. Overtime, the bay has gone through countless changes resulting in its today’smagnificent natural landscape. 

The core area, where has been recognised by the UNESCO as a World NaturalHeritage, is 434sq.km and comprises of 775 limestone islands and islets./.
