A Sầu Valley

The A Sầu Valley, also known as the A Shau Valley, is a valley in Vietnam's Hue province, along the border of Laos. The valley runs north and south for about 40 kilometers and is a flat, 1.5 kilometer wide bottomland covered with tall elephant grass, flanked by two densely forested mountain ridges whose summits vary from 900 to 1,800 meters in elevation. It was one of the key entry points into South Vietnam for men and material carried along the Ho Chi Minh trail by the North Vietnamese Army and was the scene of heavy fighting during the Vietnam War; it is bisected lengthwise by Route 548, and the Ho Chi Minh Highway now runs along the valley floor.
