Nui Coc Lake
A reservoir among the Thai Nguyen tea hills, with a legend about two lovers turned into water and a mountain.
Updated 21 October 2026
Nui Coc was created in the 1970s by damming the Cong river for irrigation, and the reservoir now covers a couple of thousand hectares with dozens of wooded islands and the tea hills of Thai Nguyen around it. The name comes from a legend: a poor young man, Coc, and a mandarin's daughter, Cong, were separated, and her weeping became the river while he became the mountain that watches it - a story the resort has built heavily around. Boats run to the islands. The resort side has theme-park attractions, and the lake and the tea country around it are the heart of a visit.
