Tunnels Of Củ Chi, Ho Chi Minh City, Saigon, Vietnam

The 75-mile (121 km)-long complex of tunnels at Củ Chi has been preserved by the government of Vietnam, and turned into a war memorial park. The tunnels are a popular tourist attraction, and visitors are invited to crawl around in the safer parts of the tunnel system. Some tunnels have been made larger to accommodate the larger size of Western tourists, while low-power lights have been installed in several of them to make traveling through them easier and booby traps have been clearly marked. Underground conference rooms where campaigns such as the Tết Offensive were planned in 1968 have been restored, and visitors may enjoy a simple meal of food that Viet Cong fighters would have eaten.
Above-ground attractions include caged monkeys, vendors selling souvenirs, 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.
