Dau Dang Waterfall was formed from the Nang River, about 16km from the center of Cho Ra town, Bac Kan. Water flows under Lung Nham limestone mountain and forms Puong cave. When flowing to Hua Tang village in Nam Mau commune, they encountered hundreds of large and small rocks blocking them. The terrain in this position has a slope of about 500m, thus creating the majestic and impressive Dau Dang waterfall today.
