Cu Chi, 65km northwest of Ho Chi Minh City, became internationally famous during the world for the network of tunnels over 250km in length. The tunnel network is not only the shelter for a community like other villages but also the significant revolutionary base in the anti-French and anti-U.S wars. Tourists will be astounded by discovering that the 250km tunnels are designed by Cu Chi guerrillas but not by any architect with 3 levels including meeting halls, kitchens, field hospitals, living areas, storage facilities and commanding centers.
