Nho Que River
The Nho Que River is a scenic river flowing through Meo Vac District in Tuyen Quang Province (formerly Ha Giang), northern Vietnam. It runs at the foot of Ma Pi Leng Pass and through Tu San Canyon, the deepest canyon in Vietnam. Notable for its emerald-green water and dramatic karst limestone cliffs, the river is a central feature of the Dong Van Karst Plateau UNESCO Global Geopark and is primarily visited via boat tours.
