They are part of a larger network of tunnels stretching over 250km from Ho Chi Minh City to the borders of Cambodia . Initially, the tunnels were dug by the Vietnamese Communist guerrilla troops - Viet Cong - during the Indo-China War but the network of tunnels expanded during the Vietnam War in 1960s. The guerrillas and North Vietnamese troops dug the tunnels using their bare hands. The tunnels were used for various purposes including as hideouts, a place to store food, medical supplies and weapons as well as a place to discuss strategies against the enemies and to plan traps and ambushes. The natural environment was ideal to conceal the entrances of the tunnels as well as traps and land mines. When the American military heavily relied on aerial bombings, Cu Chi Tunnels provided safe haven for the guerrillas because the tunnels were built using soil known as laterite clay, thanks to the close presence of the Saigon River, which was a source for the material . During rainy seasons, the soil was very soft and therefore, guerrillas were able to dig and shape the interior pathway without extreme difficulty . However, during dry seasons, the soil turned extremely hard, thereby providing stability to the tunnels. Over time, the tunnels grew to house an entire underground village and even had artillery factories, bomb shelters, hospitals, living areas and kitchens .
