The tunnels were originally dug by hand using simple tools, often at night to avoid aerial detection.
The ventilation systems for the underground kitchens were designed to vent smoke away from the exit points to prevent discovery.
US forces utilized 'tunnel rats'—soldiers specifically trained to enter and clear the narrow, dark passages.
The tunnels were located on multiple levels, with the deepest level reaching up to 10 meters underground.
The Cu Chi base included decentralized underground command centers that allowed for coordination of the Tet Offensive in 1968.
A specialized type of sandal made from recycled rubber tires was worn by combatants to leave misleading footprints.
The tunnels housed specialized 'hospital' chambers for treating malaria, which was a constant threat to those living underground.
The Cu Chi Tunnels consist of an immense network of connecting underground passages used by Viet Cong soldiers as hiding spots and supply routes during the Vietnam War. Located in the Cu Chi District, the site features preserved segments of the original labyrinth, including living areas, weapon factories, and field hospitals. Visitors can traverse portions of the tunnels, which were widened in certain areas to accommodate international tourists. The site displays original booby traps, bunker systems, and a decommissioned tank to illustrate guerrilla warfare tactics. The soil in this region is made of laterite, which provided the structural integrity necessary to prevent the tunnels from collapsing. The network expanded to cover hundreds of kilometers, reaching as far as the Cambodian border during its peak usage.

Maintain a respectful demeanor as this is a memorial site; wear modest, breathable clothing.
