Du Già Waterfall - known locally as Thác Ba Tiên (Three Fairies Waterfall) for the way the water cascades down in stepped tiers resembling the flowing hair of fairies - sits in a narrow valley in Yên Minh district on the eastern Ha Giang Loop. The falls drop 6m over a 2m-wide face into a clear green pool, peaceful rather than powerful.
The water originates from the forest above, passing through mountain rock crevices before reaching the pool at the base. This is not a waterfall that impresses with scale or drama - it's a swimming hole with a cliff jump and cold clear water, which in the context of the dusty, physically demanding Ha Giang Loop is exactly what it needs to be. Cliff jumping here became popular with foreign visitors from around May 2023 - two levels are available, at 3.5m and 6m above the water.
