If you’re looking for a general overview of the DMZ, we’d usually include the main sites, the bridges, the Vinh Moc and the Truong Son National Cemetery. Possible sites could be La Vang Church, the Quang Tri Citadel, the Ai Tu Base and Airfield, Camp Carroll, The Rockpile, the Khe Sanh Marine Combat Base, Lang Vay Special Forces Camp, Con Thien Firebase, the McNamara Line, the Dak Rong Bridge, and the Doc Mieu Base. The Ben Hai River and the Hien Luong bridge would also feature. The river runs about 100km from its source to the sea, but was catapulted onto the international stage when the 1954 Geneva Convention designated it as the demarcation line between the communist North Vietnam and the South (not the ‘17th Parallel’ often mentioned in guide books).
