Cat Ba National Park covers 17,362 hectares, and is recognised as the UNESCO Biosphere Reserve.
The Ang Rang area located in the park’s core zone is among the areas hardest hit by the typhoon.
Travelling along the 21-kilometre road in the park, it's easy to spot trees damaged in the aftermath of the typhoon.
Authorities have assessed that it would take 3-5 years or even longer for Cat Ba National Forest to fully recover. Meanwhile, the time for the vegetation to return would be between six months and a year.
The park is home to many valuable tree species and large trees that are several decades old.
Cat National Park accommodates 282 plant species and nearly 800 animal species along with lots of archaeological sites here, showing that humans have inhabited the area for millennia.
Cat Ba has many stunning caves and karst valleys such as Trung Trang, Hung Son, Gia Luan and Tai Lai.
