Birds among rocks, forests and vineyards
Practically since its entry into Galicia to its confluence with the Miño, the Sil river opens from the east to the west embedded in a deep valley that separates the provinces of Lugo and Ourense. Much of this section is dominated by large walls and granite crags that plummet over the waters of the now-dammed Sil river.
The south-facing slopes enjoy significant sunshine that for centuries has enabled the cultivation of vineyards, many of which on small farms that have practically opened between the rocks. The natural vegetation growing on these sunny slopes consists of oaks, cork oaks, strawberry trees and other Mediterranean species, while the north-facing slopes are home to well-preserved oak (occasionally mixed with chestnuts) due to its vertiginous drop. At the edges, small villages surrounded by fields and pastures complete the general setting of an area of great environmental diversity
