Transfer by car along the Ho Chi Minh trail to get to the Phong Nha - Ke Bang National Park. This site presents a landscape of karstic plateaus and tropical forests, which are diverse from a geological point of view and offer spectacular phenomena including numerous caves and underground rivers. It is home to a high level of biodiversity and many endemic species. The National Park ensures a more intact ecosystem, providing additional protection to watersheds of vital importance to the integrity of karst landscapes. We will take a cruise along the Son River to visit Phong Nha Cave (the most famous in the national park) then check in at your hotel. 

This morning, we head to Paradise Cave (or Dong Thien Duong), in the Phong Nha – Ke Bang National Park, UNESCO World Natural Heritage Site. Discovered by local man; Ho Khanh in 2005, Paradise Cave is a 31.4km long cave, but only the first kilometre has been opened to tourists (since 2010). You will have the chance to see one of the largest and most impressive accessible caves in the area. After climbing the 524 steps, you will be welcomed generously by cool breezes blowing from the small open door of the cave. Overnight in hotel.

After breakfast at the hotel, we will drive to Hue via Quang Tri. There will be some visits and short breaks en route. The first visit is to the DMZ, where some of the bloodiest battles took place during the War against America. In the late morning, we will take the impressive tour of the Vinh Moc tunnels, preserved as a monument to the determination of the Vietnamese to continue living in their traditional village areas. The whole village was moved below ground and the people lived in these subterraneous tunnels and caverns. Our next stop is to visit Hien Luong bridge and Ben Hai River, two "historical witnesses" who carried the pain of being the point of separation between North and South Vietnam for more than 21 years. The nearby museums tell a hard story of the resistance war against the US, full of sacrifice and hardship for the Vietnamese army and people. We continue driving to Hue with a stop at a small church still bearing the scars of a mortar attack in the area.
