Covering an area of nearly 2,000 hectares, the Trang An scenic landscape complex is divided into five areas, which are a special conservation area (ancient capital of Hoa Lu), the core area, a cave area, tourism service areas, and the spiritual tourism area of Bai Dinh pagoda mountain.
The complex is home to 47 historical relics with numerous caves inside stunning limestone karst mountain ranges. The picturesque landscape of Trang An is a harmonious combination of mountains, valleys, and a system of lakes.
Sitting on a small boat floating in the green lake, visitor will be amazed by the shades of mountain range reflected in the clear water, various kinds of wild flowers and some grazing goats under trees.
The labyrinth of caves in Trang An appeals to visitors thanks to its mysterious features. The caves have stood the test of time and the elements. They are decorated with stalactites and stalagmites in unique shapes.
Around 50 submerged caves act as gateway leading to other valleys with a total length of 20km. Some caves are big, such as Hang Toi (Dark cave) which is 315 m long and 60m high.
Discovering the cave system of Trang An scenic landscape complex, visitors can see with their own eyes why Trang An is called “Ha Long Bay on land”.
Moreover, Trang An owns a rich and diverse ecological system. The area is surrounded by primeval forests with a large number of fauna and flora species. There are 500 different types of plants, 73 species of birds, 41 species of animals and 31 reptile species within the complex.
The Trang An scenic landscape complex was recognised as a World Cultural and Natural Heritage site by UNESCO in 2014.-
