Barreiro is a picturesque inverneira located on the west slope of the Laboreiro Valley at about 850 meters above sea level. It is set in a uniquely scenic landscape where the settlement is surrounded by water meadows and these in turn by the superb Barreiro oak woods.

Families from the brandas of Adofreire, Antões, Falagueiras, Outeiro, Queimadelo and Rodeiro came here to spend the winter in Barreiro. Nowadays, there are few families that still use the inverneira as a seasonal dwelling. Despite this, the place is relatively well-maintained and the fields reasonably cared for.
