Ba Be Lake sits within Ba Be National Park in Bắc Kạn province, approximately 230km north of Hanoi. The lake is actually three interconnected bodies of water - Pé Lèng, Pé Lù, and Pé Lầm, known collectively as Slam Pé in the Tày language - stretching 8km through a valley of karst limestone mountains at 125m elevation. The lake reaches 20-25m deep on average, 35m at its deepest.
It was recognised as one of 20 freshwater lakes globally requiring special protection at the 1995 World Freshwater Lake Conference, designated a national historical and cultural monument in 1996, and became a Ramsar Wetland site in 2011.
The Tày Legend of the Lake
According to Tày legend, the lake formed when the earth swallowed a village that had been cruel to an old beggar woman - who was a fairy testing their hearts. Two mothers and children who showed kindness were warned and escaped; the rest were swallowed by the rising waters. The three sections of the lake reflect the three valleys that filled.
Bản Pác Ngòi
The Tày communities around the lake - most notably Bản Pác Ngòi with its 80+ stilt houses - have maintained this landscape for generations.
