Ba Be, a sprawling expanse covering 10,048 hectares, earned its status as a National Park in 1992 and later secured its place as an ASEAN Heritage Park. Enshrined within the park's heart, Ba Be Lake comprises three smaller lakes orignally "slam pe" in the local Tay language. The three lakes - Pe Leng, Pe Lu and Pe Lam - are indeed three sections of the same water body. Ba Be Lake is Vietnam's third Ramsar site as listed by UNESCO, elevating its status as a vital global wetland. Nestled at 145 meters above sea level, with an average depth of 20 to 25 meters and a maximum depth of 35 meters, Ba Be Lake reigns as Vietnam’s largest tectonic lake created by the collapse of the late Cambrian karst formation. The majestic karst limestone massif harbors captivating caves within their depths.
