For those interested in Vietnam War history, taking a day trip from Hue to the DMZ (Demilitarized Zone) is a poignant and educational experience. This area, straddling the former border between North and South Vietnam along the Ben Hai River, was the site of intense conflict.

Guided DMZ tours typically visit key historical sites like the Vinh Moc Tunnels (an underground village), the Khe Sanh Combat Base, the Hien Luong Bridge (the symbolic dividing line), and Rockpile Hill. It's a sobering but important journey offering insights into the hardships and resilience during the war.
