Hang Chi Huy (also known as Hang NH) used to be a strategic logistics warehouse of Command 559 in the resistance war against the US. The cave is 150m long, 100m wide, with 7 floors, now restored into a lively exhibition space, associated with stories about the historic Truong Son road.
This is a destination that has just been put into operation in the "Legendary Truong Son Road - Hang Chi Huy" Eco-tourism Area on July 5.

On the first day of launch, this experience attracted nearly 500 visitors, including foreign tourists.
At the beginning of the tour, visitors cross Road K - a winding road under the forest canopy, to enter the journey opposite the flow of time.
At the exhibition area, visitors can witness with their own eyes the road opening tools, logistics goods, bomb and bullet shells, and especially the recreation of the operating space inside Hang Chi Huy with 7 functional floors: from the medical treatment area, cargo warehouse, command communication to the soldier's resting place.
The special highlight of the tour is the virtual reality show with 9D technology, allowing visitors to "transform" into soldiers driving Zil-131 to cross Road 20 in the rain of bombs and bullets. With 360-degree images, wind effects, gun smell and movement, each segment will bring an emotional and realistic experience.

According to the leader of the People's Committee of Quang Tri province, this is a new tourism product in the ecotourism, resort, and entertainment project of Phong Nha - Ke Bang National Park for the period 2021 - 2030 approved by the Provincial People's Committee.
Therefore, Phong Nha - Ke Bang National Park Management Board needs to continue to coordinate with relevant departments and branches to improve management quality, ensure safety for tourists, focus on the conservation of natural resources, historical relics and environmental landscape conservation.
Thereby, bringing visitors impressive multi-sensory journeys, contributing to honoring the majestic and unlimited beauty of the Phong Nha - Ke Bang cave system.
Mr. Nguyen Chau My - General Director of T20 Quyet Thang Company Limited, the unit that built this product, reviewed the tour as bringing a new experience at a "red address" in Phong Nha - Ke Bang National Park. The journey helps domestic tourists have the opportunity to visit one of the historical relics considered a legend from a very different perspective.
This is a tourism product combining historical education and nature conservation, aiming at sustainable development, while creating a new highlight in the local tourism ecosystem.
