Here, 14 caves have been discovered in primeval forests on limestone mountains, forming an original landscape.

Within the park, there are three peaks: Voi (1,387m), Ten (1,244m) and Can (1,144m). Most of caves in these mountain ranges are the habitat of bats. Entering the caves, you can be shocked by various strange-shaped stalactites and stalagmites. Many caves, despite their narrow entrances, are very large, housing hundreds of people. There are some caves running 7-8km inside the mountains.
