The document discusses visiting the Cu Chi Tunnels in Vietnam. Located 70 km from Ho Chi Minh City, the Cu Chi Tunnels can be reached by bus, motorbike, or car rental. Visitors purchase tickets and then explore the tunnels either on foot or via electric bus. They see a temple and watch an introductory video before crawling through some of the 200 km of tunnels, getting a sense of what life was like for soldiers during the war. Other attractions include an outdoor museum and spike traps. A day trip to the Cu Chi Tunnels offers a more fascinating experience than expected.
