Fairy Stream - Suối Tiên - is a shallow freshwater stream that flows from inland dunes and forest to the sea through a narrow sandstone canyon, between Võ Nguyên Giáp and Huỳnh Thúc Kháng streets, about 1km west of Mũi Né town centre. The canyon walls rise a few metres in layered red, orange, and yellow sandstone - the colours produced by varying concentrations of iron oxide in the compressed sand - interspersed with sections of bamboo overhanging the water and open dune gaps where the sky appears above.
The stream itself is now quite shallow, typically only ankle-deep, and sandy-bottomed, waded in water shoes or sandals (rather than barefoot, given sharp rocks and debris underfoot) toward a small waterfall and pool at the upper end, roughly 1.8-2km from the entrance.
According to some long-time locals, the stream was considerably deeper and more scenic 10-15 years ago - old Vietnamese fairy-tale films and TV shows were reportedly filmed here in that era - but construction of Road 706B near the stream's source is said to have reduced its flow over time, with dune sand gradually silting up what remains; some locals now rarely visit themselves, even as it stays popular with tourists.
The walk is simple and requires no special equipment, which makes it an accessible, low-key stop - though, like several popular spots in Mũi Né, it also attracts some unofficial fee collectors and pushy touts, so it pays to know the real entrance situation in advance.
