Pu Luong is a nature reserve in Thanh Hoa province, known for its stunning terraced rice paddies, valleys, rivers, and waterfalls. It is a popular destination for ecotourism, trekking, and cultural immersion, as it lies within the Thai ethnic village area and has remained relatively untouched by mass tourism. It is located approximately 150 km southwest of Hanoi and about 125 km northwest of Ninh Binh.
