Topography
Three quarters of Vietnam's territory consists of mountains and hills. Vietnam is divided into four distinct mountainous zones.
The Northeastern Zone (Viet Bac)
This zone stretches from the Red River Valley to the Gulf of Tonkon. The mountainous area of Viet Bac is scattered with famous sights: Dong Nhat Grotto, Dong Nhi Grotto, and Tam Thanh Grotto in Lang Son Province; Bac Bo Grotto and Ban Gioc Waterfall in Cao Bang; Ba Be Lake in Bac Kan; Yen Tu Mountain and Halong Bay in Quang Ninh; and Tay Con Linh, the highest mountain peak in the region reaching 2,341 meters above sea level.
The Northwestern Zone
This zone is comprised of mountains that run from the north of the Sino-Vietnamese border to the west of Thanh Hoa Province. This magnificent mountain range is nationally known for its resort town of Sapa in Lao Cai Province, which is perched 1,500 meters above sea level. Several ethnic groups, such as the H'mong, Dao, Kinh, Tay, Giay, Hoa, and Xa Pho, still reside in this region.
The northwestern zone is also famous for the historical site of Dien Bien Phu and Fansipan Mountain, which measures 3,143 meters above sea level at the peak.
The North Truong Son Zone
This zone runs from the western part of Thanh Hoa Province to the Quang Nam-Da Nang Mountains. This region is known locally for its picturesque Phong Nha Grotto and its two breathtaking passes, the Ngang Pass and the Hai Van Pass. It is also known worldwide for being the location of the legendary Ho Chi Minh Trail constructed during the second great resistance war.
The South Truong Son Zone
This zone is located to the west of the south central coast provinces. Behind these huge mountains is a vast area of red soil known locally as "Tay Nguyen" (the Central Highlands). There are numerous legendary accounts of the flora and fauna and of the lives of several different ethnic minorities living in the Central Highlands. Dalat, established during the 19th century, is a popular resort town in this part of Vietnam.
Vietnam has two major deltas, including the Red River Delta in the North and the Mekong River Delta in the South.
