What is the terrain and geography like in Vietnam?
Vietnam’s northern terrain is mostly mountainous or hilly, with some highland areas covered by a thick green blanket of jungle (about half the total land area). The Red River Delta and coastal plains in the lowland part of the North are heavily populated and intensively cultivated (almost entirely by rice fields). Although much of this Delta Region is seasonally flooded, a complex network of dikes and levees helps to prevent serious flood damage.
The southern part of Vietnam is dominated by the estuary of the Mekong River system and is low, flat, and frequently marshy. The rich soil in the Mekong Delta is the most fertile in the country. Areas immediately north and east of Ho Chi Minh City in the Mekong Delta are much more varied with low-lying tropical rain forest, upland forest, and the rugged Annamite Mountain chain.
In the south, Ho Chi Minh City and the Mekong Delta experience a year-round tropical climate with daily temperatures normally exceeding 88°F. The rainy season in Danang and Hue in the center of the country lasts from October to March.
