Location: Streaming through a valley between Huyen Dinh and Yen Tu mountains, Mo Spring is located in Nghia Phuong Commune, Luc Nam District, Bac Giang Province. This beautiful attraction is about 90km from Hanoi and 40km from Bac Giang City.

Characteristics: due to geological structure, Mo Spring has lots of huge rocks formed in different shapes. These stones are positioned in tiers to make different levels of slopes within the stream bed, which creates various falls of different sizes. Consequently, there appeared many natural bath tubs. Along both sides of the stream are luxuriant trees looking into the clear water.
