The waterfalls are a favorite side trip for tourists in Luang Prabang, and begin in shallow pools atop a steep hillside.
The water flows and falls in three cascade waterfalls over white limestone rocks into aquamarine turquoise (color) pools[9] surrounded by tropical trees.
The source of Nam SI is located at the foot of the mountains where the Hmong people and Lao Theung, Khmu hill tribes once lived.
Due to slash-and-burn rice farming in the mountains and valleys by Hmong and Khmu farmers, the Nam Si River experienced drought.
After 1975, the Lao government relocated the hill tribes to other places in the area to restore natural resources.
