The heroic history of Commander Cave Museum on Victory Road 20
The Truong Son Route, also known as the Ho Chi Minh Trail, served as a strategic transport network during the American War. It transported thousands of tons of supplies, weapons, and food from the North to the southern frontlines. Among the Truong Son road system, Victory Road 20 was one of the most important routes. It was also one of the fiercest “fire coordinates,” heavily bombed during the war.
Located at Kilometer 12 on this historic route, Commander Cave Museum was also known as NH Warehouse, NH Cave, or the Seven-Level Cave. It served as an important logistics base for Station 14 under Command 559. Active from 1967, this natural cave stretched 150 meters long and 100 meters wide. Soldiers and engineers reinforced it into a seven-level structure inside the limestone mountain.
The history of Commander Cave Museum is closely linked to many vital military functions. It served as a secure shelter and hosted important secret meetings for battlefield commanders. The cave also worked as a frontline warehouse storing food, weapons, ammunition, fuel, and military equipment.
The cave also operated as a field hospital, treating wounded soldiers along the frontline. In addition, troops used the site as a mechanical station to repair transport vehicles before crossing difficult routes.
During the years of war, more than 8.000 soldiers, youth volunteers, and workers served on this frontline. They carried rice, ammunition, and supplies through steep forest trails to keep the transport route open. The Truong Son Commander Cave remains the strongest reminder of their courage and determination.

What you can see and do at Commander Cave Museum
The special appeal of Commander Cave Museum lies in how it recreates history. The site combines untouched landscapes with modern technology to tell authentic stories.
1. Unique VR 9D experience
The VR driving experience features advanced 9D technology and VR360 systems. It is one of the most popular attractions at the site. Visitors can sit inside a recreated Zil-130 military truck model.
After wearing the VR headset, guests begin a multi-sensory journey back to wartime Vietnam. The experience takes visitors to one of the country’s most intense battle zones.
Mechanical motion systems work together with realistic sound, lighting, and vibration effects. These recreate bomb explosions and B52 air raids in vivid detail. Visitors feel as if they are driving through the dangerous Truong Son route. The experience ends with the peaceful green forests of present-day Phong Nha.
To maintain quality and safety, visitor numbers remain limited for each full tour. This experience offers more than visual effects. It brings history to life, especially for younger visitors who only know Truong Son through books.
2. Road K and the road-building exhibition area
Before entering the cave, visitors walk through the hidden K Road beneath the dense forest canopy of Phong Nha – Ke Bang National Park. Along the route, visitors can explore displays of tools used to build Victory Road 20.
These simple tools represent the strength of over 8.000 workers and soldiers. Youth volunteers and transport teams created a remarkable achievement. They completed the 125 km strategic route in only 77 days and nights. The road connected Phong Nha in Vietnam with Lum Bum Junction in Laos and opened supply access to the South.
3. Bombshell battlefield and anti-aircraft weapons display
Another must-see area is the bombshell exhibition beneath the forest canopy. The site displays bomb fragments and artillery shells dropped by the US military on Victory Road 20.
In contrast, restored anti-aircraft guns stand ready in defense positions. The limestone mountains protected the cave from aircraft approaching from the sea. The terrain also helped soldiers build defensive lines against enemy planes.
4. Discover the seven levels inside the cave
Inside Commander Cave (NH Warehouse), visitors will be amazed by the giant natural chamber. The cave stretches 150 meters long and reaches 100 meters wide. Since 1967, it was transformed into a seven-level military complex. Today, reconstructed displays and statues recreate its original functions:
- Level 1: The field surgery and initial first aid station. It received wounded soldiers from the Truong Son frontline for emergency treatment before moving them to the rear. Visitors can still see original cement platforms used for stretchers and old medical tool traces.
- Level 2: The strategic logistics warehouse. This level specialized in storing weapons, ammunition, grenades, medical supplies, and essential equipment to promptly supply advancing troops.
- Level 3: The communication center. Serving as the vital lifeline of battlefield operations, it was responsible for receiving, processing signals, and maintaining 24/7 communication between the main headquarters, station outposts, and transport convoys.
- Level 4: The command head office. Key commanders stationed here 24/24 to process battlefield intel and direct the movement of troops and supplies. This level also marks where General Dong Sy Nguyen lived and worked during strategic operations.
- Level 5: The long-term reserve and heavy weaponry storehouse. Large artillery pieces, high-grade explosives, and neatly arranged stacks of rice and ration boxes were kept here to supply other stations in the network.
- Level 6: The mini-museum exhibition area. This level carries unique historical value, displaying authentic artifacts recovered during the cave’s restoration, such as bombshells, military batteries, old penicillin bottles, fountain pens, and rubber sandals.
- Level 7: The living and meeting area. Located at the highest and widest section of the cave, it provided space for meetings, strategy planning, and relaxation where soldiers shared stories from the home front to maintain morale.
