The South — Southern Vietnam, called Nam Bo, is home to Vietnam’s largest city, bustling Ho Chi Minh City, also known as Saigon. Vietnam’s largest cosmopolitan area is like a region unto itself, with a population of more than eight million spreading out over a wide area of urban and suburban sprawl. Tay Ninh is a town just to the north and west of Saigon that’s home to the unique Cao Dai sect and the end of the Ho Chi Minh Trail at the Black Mountain. Some of the heaviest fighting during the war took place here, much of it planned from the tunnels of Cu Chi. The south is hotter, in climate as well as cuisine.
South of Ho Chi Minh City is the Mekong Delta, where, after a 4,500km (2,790-mile) journey from the mountains of Tibet, the mighty Mekong splits into nine smaller branches and a wide alluvial plain as it deposits its silt on the way to the South China Sea. The well-irrigated delta is the most agriculturally productive region of Vietnam, where most of the country’s rice is grown, and where the population has swelled in recent years with increased productivity and industries like fish farming and shrimp cultivation. The climate of the delta is tropical; the lower delta is untamed swampland. The region shows the influences of ancient Funan and Khmer cultures, as well as the scars from recent wars (the Viet Cong used the delta as a secret base) and battles with neighboring Cambodia.
