There are 2 groups of settlements that is actually within the same area of 'tribe village/desa adat'. It is close to Sawah Lunto (another TWHS) so one can visit both in 1 go.

The villages consists of many traditional houses that's very well preserved. They're still in use for real. I happen to visit one of the houses and see the making of their traditional cloth. A 2 hrs visit is already OK to see all.
