There are many hydrodynamics here, visitors can walk on the road while can take a boat ride on the river. When entering the caves, the feeling of mystery and excitement is wonderful. The entrance of the cave is small, but dozens of boats enter. Inside, sparkling stalactites flow on the walls of the cave creating vivid wonders. The caves also have very unique names such as Tran cave, Brewery cave, Ba Giot cave ... the largest is Tran cave. They are interconnected and can be up to nearly twenty kilometers long.

Located within Ninh Binh Province of North Vietnam near the southern margin of the Red River Delta, the Trang An Landscape Complex (Trang An) is a mixed cultural and natural property contained mostly within three protected areas; the Hoa Lu Ancient Capital, the Trang An-Tam Coc - Bich Dong Scenic Landscape, and the Hoa Lu Special-Use Forest. The property covers 6,226 hectares within the Trang An limestone massif, and is surrounded by a buffer zone of 6,026 hectares, mostly rural land with rice paddy fields. There are about 14,000 residents, the majority of whom are families involved in subsistence agriculture, but much of the property is uninhabited and in a natural state. Trang An is of global significance as an outstanding humid tropical tower-karst landscape in the final stages of geomorphic evolution. It is composed of a variety of classical karst cones and towers and a network of enclosed depressions connected by an intricate system of subterranean waterways, some of which are navigable by small boats. The area is unique in having been invaded by the sea several times in the recent geological past but is now emergent on land. The blend of towering mountains draped in natural rain forest, with large internal basins and narrow cave passages containing quietly flowing waters, creates an extraordinarily beautiful and tranquil landscape. Archaeological deposits in caves reveal a regionally significant, continuous sequence of human occupation and utilization spanning more than 30,000 years. There is convincing evidence showing how early human groups adapted to changing landscapes in the massif, including some of the most extreme climatic and environmental changes in the planet’s recent history.
