Most tours of Dalat will take in a tea plantation, as one of Dalat’s staple products. Cau Dat, around 20km from Dalat and 1,650 metres above sea level, is where the Vietnamese tea industry originated, with the Dalat Cau Dat Tea Company. Tea plantations from Holland and France were planted in 1922, and the French brought in the tea processing machines. Tea trees cover 230 hectares of Cau Dat, marginally less than Bao Loc, the other major tea producing region. Cau Dat grows high quality black tea and Oolong tea varieties, but the specialty is the green tea, said to take on the flavour of the morning dew. It is possible to arrange a tour of the Cau Dat Tea area, through any of the tour operators in Dalat.
