Suoi Mo Stream is situated in Nghia Phuong commune, Luc Nam district, Bac Giang province, about 90km from Hanoi. It was recognized in 1988 as a historical relic by the Ministry of Culture and Information of Vietnam.
Due to geological tectonics, there appeared many large stones which are placed in tiers, making different levels of slopes within the stream bed, and results in various falls of different sizes. As results, many natural bath tubs have been formed. Along both sides of the stream are luxuriant trees looking into the clear water.
There are Suoi Mo Temples consist of Den Thuong (upper temple), below along the spring are Den Trung (middle temple) and Den Ha (lower temple) which were built during Le Dynasty.
