Serra da Enciña da Lastra Natural Park

Serra da Enciña da Lastra Natural Park lies in the municipality of Rubiá, in the Valdeorras district of the Ourense province, Galicia, right on the border with the Bierzo region of Castile and León. The park was declared a protected natural area on April 4, 2002, and covers a little over 3,000 hectares — precisely 3,151.67 ha. It is one of Galicia's smaller natural parks, but one of its most distinctive in landscape terms.

What makes this park different from other parks in Galicia?

The park's centerpiece is a limestone valley with steep slopes and rocky cliffs, an unusual geological feature in a region otherwise dominated by granite and slate. The highest points of the mountain range are O Piornal, at 1,529 meters, and Pena Tara, at 1,089 meters. This limestone base is what allows for the park's surprisingly Mediterranean character in an area normally associated with an Atlantic climate.

What kind of vegetation grows here?

Serra da Enciña da Lastra holds the largest area of holm oak forest in all of Galicia. Alongside the holm oaks (encinas), the park features chestnut woodlands and meadows fragrant with wild thyme — vegetation more typical of Mediterranean Spain than of the humid Atlantic Galicia most visitors expect. More than 450 species of vascular flora have been recorded in the park, at least 40 of which are endemic to the Iberian Peninsula. The park is also notable for its orchids, with over 25 species identified, making it one of the region's most important sites for orchid diversity.

Where does the park's name come from?

The name comes from a single, large holm oak (encina) that, according to local tradition, served travelers for generations as a landmark to avoid getting lost in this rugged, mountainous terrain. That tree eventually lent its name to the entire protected area.

What other protection status does the area have?

Beyond its natural park designation, the area is also part of the Natura 2000 network: it holds status as a Special Protection Area for birds (ZEPA) and as a Special Area of Conservation (ZEC), reflecting its ecological value for both plant life and bird populations.

How can visitors explore the park?

A network of ten hiking routes runs through the park, ranging from 1.5 to 8.6 kilometers in length and covering a range of difficulty levels, so visitors can choose a route that fits their fitness level and available time. The trails wind through limestone gorges, holm oak forests, and viewpoints overlooking the Valdeorras valley and the neighboring Bierzo region.
