It is hard to believe the conflict that once existed in the beautiful and now peaceful district of Cu Chi. Underneath the rubber trees in Cu Chi lies vast network of underground tunnels, extending from outskirts of Saigon all the way to the Cambodian border.

Cu Chi Tunnels

The Cu Chi Tunnels construction began in late 1940 by Viet Minh while fighting the French colonialists. They used the tunnels as a hiding place from the French air strikes. The communist guerrilla troops known as Viet Cong, continued construction of the tunnels into the Vietnam War, or the American War as it’s called in Vietnam.

Cu Chi district is part of the Iron Triangle, a 300 square km area supportive of the Communist regime, both during the French and American War. The area remained a stronghold of the National Liberation Front during the war.

Strategically, the Cu Chi Tunnels location was an important post in the Ho Chi Minh Trail which was used to transport troops and supplies from North to South.



By the end of the Vietnam War, the tunnel system is thought to have been close to 250 km, or 155 miles. Peasants and villagers from nearby villages dug the tunnels along with the Viet Cong. Excess mud had to be disposed off during night, either to the Saigon River or nearby rice fields.

The Cu Chi Tunnel system became a underground village. It would have kitchen, school, workshops, living quarters, meeting rooms, bomb shelters, weapon factory and even hospitals.

The Viet Cong, or the National Liberation Front used the tunnels to hide against the U.S. Military and South Vietnamese troops. They would transport communication, supplies and troops within the tunnel system as they moved closer to Saigon.

The Vietnam War Tunnels proof to be a strategic advantage for the Northern Vietnamese Army. The U.S. Military had built much of their military strategy around aerial bombing, which had forced the Viet Cong underground. Facing a much better equipped military, the Viet Cong turn to guerilla tactics. They would leave the tunnels at night for an ambush and make a quick return to the tunnels.

The U.S. Military and the South Vietnamese forces recognized the advantage of the tunnels and made several attempts to take over the area. Most of the attempts were unsuccessful. The 2 major attempts to take over the area was Operation Crimp in 1966 and Operation Cedar Falls in 1967.

Operation Crimp was combined effort of B-52 bombers and 8,000 U.S. and Australian troops. Despite the massive effort and extensive bombings, it was unsuccessful. In Operation Cedar Falls, the U.S. had 30,000 troops, including tunnel rats fighting the Viet Cong in Cu Chi. The carpet bombs and tunnel rats only brought short-term success as the Viet Cong took the tunnels over again few months later.

The well-built tunnels were an engineering masterpiece and the complexity of them is astonishing, specially considering they were mostly built by farmers using hands and shovels. The way they were able to dispose of any smoke from the kitchen, air ventilation and collection of water. They had escape routes and booby traps that made the tunnels very difficult to deal with for the U.S. troops.

The smoke from kitchen and weapons factory was ventilated through multi-chambered chimneys. The chimneys and ventilation holes were disguised through termite mud tubes and anthills.

After the country opened up in 1990s, the Cu Chi area was cleaned up and the tunnels have become a major tourist attraction.

Life in the Cu Chi Tunnels

The tunnels might have been strategically important and gained much advantage to the Viet Cong, but the life in the tunnels wasn’t easy. The tunnels were filled with insects, venomous centipedes, ants and rodents. Food and water were scarce and during the heaviest bombing, Viet Cong would have to remain in the tunnels for days on end.

Few places in Vietnam are as symbolic for the toughness of the Vietnamese people like the Cu Chi Tunnels.

Malaria plagued the people living in the tunnels. After battle wounds, malaria was the main cause of death of the Viet Cong. Some reports suggest that as much as half of all Viet Cong living in the tunnels were infected with malaria at any given time.

The Viet Cong would only come out at night to get supplies, mind the crops and make attacks. During the day, they would all have their tasks in the tunnels as it operated as any other village.

Tunnels were divided into 4 levels reaching down to 10 meters below the ground. 1st level was 3-4 meters down and housed ventilation and firing posts and was filled with booby traps. 2nd level housed kitchen and living quarters. 3rd level housed hospital and storage room for food and weapons. 4th level included a well for fresh water and underwater escape route to the Saigon River.

The Vietnam War Tunnel Rats

The Tunnel Rats were volunteer U.S., Australian and New Zealand servicemen that were specially trained to search and destroy the tunnels created by the Viet Cong. They would be tasked to navigate the booby traps, gather intelligence and kill enemy solders.

The Tunnel Rats were small figured solders but even so, they had a hard time crawling the tight tunnels which were only 2 – 2½ feet wide and 4½ feet tall.
