Đà Lạt or Dalat (pop. 206,105 as of 2009, of which 185,509 are urban inhabitants) is the capital of Lam Dong province in Vietnam. The city is located 1,500 m (4,900 ft) above sea level on the Langbiang Plateau in the southern parts of the Central Highlands (in Vietnamese, Tây Nguyên). In Vietnam, Da Lat is a popular tourist destination.
Da Lat’s specific sights are pine wood (forming the name: “City of thousands of pine trees”) with twisting roads and tree marigold (Vietnamese: dã quỳ) blossom in the winter. The city’s temperate weather stands in contrast to Vietnam’s otherwise tropical climate. Mist covering the valleys almost year-round leads to its name “City of eternal spring”.
Da Lat is also known as an area for scientific research in the fields of biotechnology and nuclear physics.
With its year-round cool weather, Da Lat supplies temperate agriculture products for all over Vietnam, for example: cabbage and cauliflower. Its flower industry produces two typical flowers: hydrangea (Vietnamese: cẩm tú cầu) and golden everlasting (Vietnamese: hoa bất tử). The confectionery industry offers a wide range of mứt, a kind of fruit preserve made from strawberry, mulberry, sweet potato, and rose.
According some sources, the name derives from the acronym of the Latin phrase 'Dat Aliis Laetitiam Aliis Temperiem' ("Giving Pleasure to Some, Freshness to Others"), which the French colonial government used in their official emblem of Đà Lạt. In reality, the name Da Lat derived from the language of the local ethnic group Lạt and its original meaning is "Stream of the Lạt," and the acronym above is in fact a backcronym.
Da Lat’s year-round temperate weather, standing in contrast to Vietnam’s otherwise tropical climate, has led it to be nicknamed the “City of eternal spring”. The average temperature is 18°C - 25°C. The highest temperature ever in Da Lat was 27°C, and the lowest was 6.5°C. Mist covers the adjoining valleys almost year-round. Its temperate climate also makes it ideal for agriculture. Indeed, Da Lat is renowned for its orchids, roses, vegetables, and fruits. There are nascent wine-making and flower-growing industries in the region.
There are two separate seasons in Da Lat. The rainy season lasts from May to October, and the dry season is from November to April. The average annual precipitation is 1,750mm.
Da Lat is home to the man-made, 5 km² Xuan Huong Lake. As of early 2010 the lake has been almost completely drained, due to some repair works on the locks and a bridge that control the flow of water into the lake. As of October 2011, the lake is completely filled and back to normal.
