Thac Mu Waterfall is located in Mu Hamlet, Tu Do Commune, Lac Son District, Hoa Binh Province, not directly inside Mai Chau Valley. However, the waterfall is only around 40–50 km from Mai Chau and is often included in Mai Chau package Tours and Northwest Vietnam travel itineraries. From Hanoi, travellers usually drive to Mai Chau via National Highway 6 before continuing toward Lac Son District to reach the waterfall. Famous for its crystal-clear water, peaceful mountain scenery, and natural emerald pools, Thac Mu Waterfall is an ideal destination for swimming, trekking, camping, and discovering the authentic beauty of Hoa Binh’s highland landscapes.
