The first person to explore this region was Mr. Nguyen Thong. Approximately 25 years later, in 1893, Dr. Yersin, a French immunologist discovered Dankia high lands while on an expedition to the Langbian high lands. Dankia is 10 km from the
city of Da Lat. This region reminded Dr. Yersin of his homeland, and particularly the similarities between Da Lat's evergreen forests and those in the Swiss Alps. He made the recommendation to the government to form a resort town with health spas for government officials and foreign dignitaries in Dankia.
Not long after, Dr. Tardiff, also a French citizen, had an expedition through this region and visited Dankia and Da Lat. He recommended Da Lat to the government due to the favorable water source and locale. At the time, South Vietnam was under French rule, and was known as Cochinchina. The Governor of Cochinchina personally visited Dangkia and Da Lat and decided to take Dr. Tardiff's recommendation.
