Vietnam is a country of tropical lowlands, rolling green hills, and densely forested mountains. Low-level land covers about 20% of the country.
The Red River delta is fronted by hills that rise gently into the high mountains of the northwest; the Annam Highlands cover much of the central landscape, and in the southern areas, the coastal lowlands and Mekong River Delta merge.
A fertile and narrow coastal lowland extends south from the Red River Delta to the Mekong Delta.
The Mekong Delta is a low-level plain, one inundated by hundreds of small rivers and canals. Thick jungles and mangrove swamps cover the far-southern areas of land.
The Red River (Song Hong), and the Mekong are the most significant rivers; both have numerous tributaries, and the latter is certainly among the great rivers of the world.
Vietnam's highest point is Fan Si Pan whose summit reaches 10,315 ft. (3,144 m); the lowest point is the South China Sea at 0m.
