The name Sobral says it all. Its the land of the cork oak trees (here normally known as sobreiras), some of which around the village are of huge dimension. The vegetation cover of lower lands is potentially of cork oak and as understory, the Mediterranean scrublands, where the strawberry tree is ever-present.

A large part of the relief is very rugged, in a succession of hills and cliffs increasingly high and deep. This morphology did not intimidate its inhabitants who over centuries built walls and terraces in schist, conquering metre by metre arable land and creating ingenious systems of water conduction. The schist is a very present reality throughout the territory of Sobral and is therefore rightly integrated into the network of Schist Villages.

The toponym of the charismatic peak of the parish, Gondufo peak, brings us the Germanic and magical reminiscences. Besides the magnificent landscape, it is a place that, due to its botanical interest, is part of the Natura 2000 Network Site designated as the Açor complex.
