The 60-year-old tourist was traveling with a group to the top of the mountain when she slipped while taking photos.
She was taken by local tourism staff and family members to Lam Dong General Hospital but succumbed to multiple severe injuries.
There are warning signs posted in the area where she slipped.
Langbiang is located in Lac Duong District, 12 kilometers away from tourism hotspot Da Lat. It is more than 2,100 kilometers above sea level and tourists either walk or travel by car to the top.
On Tuesday four South Korean tourists died when a flash flood swept their jeep away in Lac Duong District.
Lam Dong authorities have demanded that officials and tourism companies tighten safety measures.
