Walk through the “underground village” of Vinh Muoc in the former DMZ (Demilitarized Zone) with multi-tiered levels of homes, schools—even a delivery room, with tunnels opening to the beach. Drive through the verdant DMZ that formerly resembled the face of the moon, with scarcely a blade of grass. Visit the Vietnam National Cemetery. Tour the famous Khe Sanh battlefield, site of an epic battle when the North Vietnamese Army besieged Americans forces in this key northern strong point in the former South Vietnam. Stay overnight in Khe Sanh town. The second day we head north along the spectacular Ho Chi Minh Highway West, a seldom traveled former artery of the Ho Chi Minh Trail network used by troops (no vehicles) heading south. Enjoy breathtaking views in this rugged range of the Truong Son mountains whose spine forms the Viet-Lao border. The scenery climaxes in Ke Bang National Park as you descend through the rugged karsts and and back into the plain of Dong Hoi and the Nam Long Hotels.
