The reserve is home to the Garrano, a primitive breed of small horse native to northern Portugal.
Over 100 Roman milestones are still visible along the ancient Via Nova road that cuts through the reserve.
The landscape features 'furaos' (ferrets) and golden eagles, species rarely spotted in more populated European regions.
It preserves a distinct cultural tradition known as 'comunitarismo,' where village resources like land and ovens are shared.
The park contains the highest concentration of megalithic monuments in the region, including numerous dolmens.
The botanical diversity includes endemic species such as the Gerês iris (Iris boissieri).
The border region has historically been isolated, which facilitated the preservation of ancient agricultural terraces.
Granite geological formations in the area exhibit unique 'tors' or mushroom-shaped rock outcrops caused by erosion.
The Gerês-Xurés Transboundary Biosphere Reserve spans approximately 268,000 hectares across the border between northern Portugal and the Spanish province of Ourense. It functions as a single protected ecological unit incorporating Portugal's Peneda-Gerês National Park and Spain's Baixa Limia-Serra do Xurés Natural Park. The terrain consists of granite massifs, high-altitude plateaus, and deep river valleys formed by the Limia and Cávado rivers. It remains one of the few places in Europe where Iberian wolves and Garrano ponies roam in semi-wild habitats. The area contains historical Roman ruins, including sections of the Via Nova, an ancient road connecting Bracara Augusta to Asturica Augusta. Traditional 'lagoeiros' and stone shepherd huts are scattered across the mountainous landscape. Vegetation is characterized by oak forests, scrublands, and peat bogs. The reserve is designated as a UNESCO Biosphere Reserve due to its high levels of biodiversity and cultural heritage preservation.

Bring offline GPS maps as cellular signal is highly intermittent in the deep valleys.
Carry waterproof gear even in summer, as the mountain microclimate causes rapid weather shifts.
Ensure your vehicle has sufficient fuel before entering the park, as service stations are sparse.
Attempting to drive on unpaved fire tracks without a 4x4 vehicle; assuming international roaming data will work throughout the reserve.
Stick to marked trails to protect sensitive peat bog ecosystems; keep dogs on a leash to avoid disturbing wildlife.
