The museum is housed in an attractive stilt house with a static exhibit upstairs which runs uninspiringly through the history of the Sapa region before moving on to some slightly more engaging exhibits about the culture of the ethnic minorities.
It's like the Ethnology Museum or Women's Museum in Hanoi, but far smaller and dustier.
On our last visit, downstairs was home to a sponsored exhibit about the crafts and customs of the Hmong and Red Dao people. It specifically focuses on their handicrafts as part of the Sapa Fair Craft project to promote these traditional crafts and help provide new economic opportunities. Entry is free but a stall is located inside so you may end up paying more than you expect; it's not a hard sell though.
