Pena Corneira

Pena Corneira is a nature reserve featuring granite formations that spread across roughly 1,000 hectares through three municipalities in the O Ribeiro region. The terrain is characterized by steep cliff faces and rolling landscapes crossed by several hiking paths.

The site received official protection as a natural monument in 2008, establishing its formal conservation status. The presence of a 12th-century Romanesque church on the grounds shows that people have inhabited this area for many centuries.

The area displays traditional rural architecture through six old mills and thirty granaries scattered across the landscape, reflecting how people once lived and worked here. These structures form part of the everyday heritage that shapes the character of the reserve today.

Visitors can explore the reserve using marked hiking trails, with the main access point at A Ponte das Poldras in Leiro. Good footwear and proper equipment are important since the terrain is steep and rocky throughout.

The reserve is a climbing destination with more than 500 routes established on the granite cliffs, ranging from beginner to expert level. These vertical rock formations are among the most impressive climbing areas in the region.
