There are 39 species of animals, including nine precious species such as languor, Tibetan bear, chamois, Loris, and red-face monkey. There are nine reptiles listed in Vietnam’s Red Book such as grass-snake, varan, slow and harmless boas, and gecko.

Kenh Ga is a remarkable place, not only because it is surrounded by the same massive rocks that dominate Hoa Lu, but also because for most of the year the entire community lives on the water itself. The floating village of Kenh Ga receives relatively few visitors compared to nearby Hoa Lu and the peoples' aquatic way of life has changed little over the centuries.
The principal reason for its lack of visitors is that the village is accessible only by boat. Gliding along the river and canals, weaving one's way through the boathouses and fishing vessels of Kenh Ga is a unique experience for there is no other place in Vietnam that combines the stunning backdrop of the limestone cliffs with an authentic floating village
