Ba Bể Lake

Ba Bể Lake (, Ba Bể meaning "Three Lakes" in the local Tay language) is the largest natural fresh water lake in Vietnam, stretching about 8 kilometers in the north-south direction. The surface area of the lake fluctuates between 3 and 5 km2 between dry and wet season. Unlike many lakes in

areas, Ba Bể Lake never falls dry. Its average depth varies between 17 and 23 meters, the maximum depth is 35 meters. The lake lies about 150 meters above sea level, making it also Vietnam's highest lake. The name "Three Lakes" refers to the three parts of the lake named Pe Leng, Pe Lu, and Pe Lam. All these three parts are connected into a single continuous body of water, however. The Ta Han, Bo Lu, and Leng Rivers feed into the lake from the south and the west. During the dry season, water is drained from the lake northwards into the Nang River. During high floods in the wet season, the latter flow is reversed however, and the lake takes up water from the Nang River thereby acting as a buffer regulating flooding.


Flora and fauna

The vegetation in Ba Bể National Park mainly consists of limestone and evergreen forest. The former covers steep mountain slopes on which the soil cover is thin. The latter depends on thicker soil cover and has a higher species diversity. The dominating tree species of the limestone forest are '' Burretiodendron hsienmu'' (

Scenic landscape features

Puong Cave is a large cave in the north of the park through which the Nang River flows. The main cave is up to 50 meters high and about 300 meters long. It is inhabited by a population of 5 to 10 000 bats belonging to 18 species. The "Fairy Pond" is rock basin filled with clear water which seeps through the surrounding limestone rock. The Dau Dang Waterfall is formed by the Nang River. It consist of a sequence of rapids which stretch over a length of almost one kilometer. Widow Island is a small, cone-shaped islet near the center of the southern lake. According to the local legend, the islet was once the home of an old widow who was spared from a flood through divine intervention.
