The tour takes place on the Preguiças River, starting from the centre of Barreirinhas and rowing for about an hour and a half to the community of Tapuio, where Casa da Farinha is located. A place that keeps the tradition of that people, the manufacture of cassava flour, during our visit, we watched a presentation on the local cassava culture, then we returned to the city of Barreirinhas, after enjoying a good dip in that region.
