Cu Chi Tunnels are an immense and remarkable network of 250km linking underground tunnels, located in Cu Chi District , around 40km to the northwest of Ho Chi Minh City and stretched from the city to the Cambodian frontier.
During the French occupation in the 1940s, the tunnels were dug with simple tools and bare hands, and further expanded during the Vietnam War in the 1960s to facilitate Vietnamese soldiers control over a large rural area, supply hospitals, food and weapons. It also provides a safe refuge for the Cu Chi people: their daily lives continued as usual underneath the soil.
About 120km of this narrow underground community has been preserved and kept in the original condition to be a war memorial. Now there are two sites open for visiting: one near the village of Ben Dinh and the other at Ben Duoc.
Both sites have displays of different booby traps used during the war time.
There are also above-ground attractions including caged monkeys and a shooting range where visitors can fire a number of assault rifles, such as the M16 rifle or AK-47, as well as a light machine gun like the M60.
A trip to Cu Chi tunnels starts daily by bus from Ho Chi Minh City, and often includes a stop at the Great Cao Dai Temple in Tay Ninh.
