Only 60 km from the heart of Ho Chi Minh City, this place is one of the most important historical tourist attractions in this city. The above 200-km-long tunnels were built and used as a shelter from U.S. troops by Vietnamese soldiers during the war in Vietnam. Hospitals, kitchens, food, weapon depots and working as well as meeting rooms were in the underground tunnel complex. Visitors can experience profound sufferings of the soldiers by discovering the tunnels. Before entering the Cu Chi Tunnels, visitors will see documentary films about the destination. Furthermore, they can even try shooting with machine guns with real bullets. Furthermore, visitors can book a bicycle or motorbike tour from the city center to the tunnels. It can be said that a one-day tour to the tunnels is a must-do thing.
