Commence today's tour early at 7:30 am with the authentic drive to historic Hien Luong Bridge- a bridge cross over Ben Hai River located in 17 parallel during Vietnam War. The famous Ben Hai River was the boundary of North Vietnam and South Vietnam from 1954 until the war ended.

Arrive at Hien Luong Bridge around 10:00 am, take a walk on the memorable bridge with a well-informed guide, and learn more about the Vietnam War in DMZ, Quang Tri. Stop and spend more time at Hien Luong Museum. Then the further drive takes us to Vinh Moc tunnels. Locals build the tunnels to hide from the intense bombing in Gio Linh, Quang Tri Province in the Vietnamese Demilitarized Zone, and it was also used as the military headquarters with meeting room. Built in 1966 and used until early 1972.

The tunnels consist of kitchens, food storage, healthcare rooms, and bomb shelter. Around sixty families lived in the tunnels; as many as 17 children were born inside the tunnels. Lunch en route before the last 3.5 hours drives on Highway 1A to Phong Nha.
