Cu Chi Tunnels are located approximately 70km northwest of Ho Chi Minh City center in Cu Chi Rural District. Cu Chi Tunnels consist of more than 200km of underground tunnels. This main axis system has many branches connecting to underground hideouts, shelters, and entrances to other tunnels. Cu Chi District is known nationwide as the base where the Vietnamese mounted their operations of the Tet Offensive in 1968.The tunnels are between 0.5 to 1m wide, just enough space for a person to walk along by bending or dragging. However, parts of the tunnels have been modified to accommodate visitors. The upper soil layer is between of 3 to 4m thick and can support the weight of a 50-ton tank and the damage of light cannons and bombs. The underground network provided sleeping quarters, meeting rooms, hospitals, and other social rooms. Visiting the Cu Chi Tunnels provides a better understanding of the prolonged resistance war of the Vietnamese people and also of the persistent and clever character of the Vietnamese nation. For a place that’s physically invisible, the Cu Chi Tunnels have sure carved themselves a celebrated niche in the history of guerrilla warfare. Its celebrated and unseen geography straddles – all of it underground – something, which the Americans eventually found as much to their embarrassment as to their detriment. They were dug, before the American War, in the late 1940s, as a peasant-army response to a more mobile and ruthless French occupation. The plan was simple: take the resistance briefly to the enemy and then, literally, vanish.  Now the unseen and undeclared No Man’s Land is undergoing a revival, saluted as a Relic of National History and Culture with its Halls of Tradition displaying pictures and exhibits. The nearby Ben Duoc - Cu Chi War Memorial, where the reproduced tunnels have been built, stands as an-above ground salute to a hidden war.
