Hố Bò woods are located in Bình Dương Province 20 km north of Củ Chi, 4 km to the west of the Iron Triangle and the Saigon River and some 56 km northwest of Saigon. The woods consist of rubber plantations, sparse to dense woods, and open rice paddies with some extremely large dikes, some 1–2 metres high. The woods were used by the Viet Cong (VC) as a base area during the Vietnam War.
