Day 1: Hue - Vinh Moc Tunnels - Dong Hoi (L,D)
8am Hotel pick up by private car and local guide. En route to the tunnels at Vinh Moc we stop at Quang Tri. This town was once an important citadel city but was heavily damaged in 1972 during a spring offensive. Still, some of the original ramparts and gates remain. From here we proceed to Vinh Moc and the amazing 2.8kms of tunnels. Unlike their counterparts in Cu Chi in Southern Vietnam, the Vinh Moc tunnels remain unaltered and therefore offer an authentic view of underground life. We enter the tunnels and explore the subterranean passageways.
Later we drive on Ho Chi Minh Trail to Phong Nha  Ke Bang National Park for the night.
Overnight at Dong Hoi.
Day 2: Dong Hoi - Phong Nha National Park - Hue (B,L)
8am We take a boat trip to the famed caves at Phong Nha. The park has some beautiful limestone formations, grottoes and caves and forest. The park also contains the largest primeval forest in Vietnam and the biggest limestone mountain range on the planet. The most impressive cave - Phong Nha cave is probably the most beautiful with many fascinating rock formations with imaginative names such as The Lion, Fairy Caves, Royal Court and Buddha. Phong Nha also boasts underground rivers, large caverns and passageways and broad pristine sandbanks. Following our exploration of the caves we return to Dong Hoi for lunch before driving back to Hue arround 5pm
