Tran Hung Dao Forest Special National Monument is located at the foot of Slam Cao mountain in Tam Kim and Hoa Tham communes (Nguyen Binh district, Cao Bang province) and about 50km southwest of Cao Bang city. This is the place to keep a system of relics associated with a particularly important historical period of the Vietnamese revolution and has now become a red address on the journey to the source of Cao Bang.
