The area is crossed by the 'Geira', an ancient Roman road that still retains original stone milestones known as 'miliários'.
It is considered one of the best-preserved examples of oak forest in Europe.
The forest serves as a vital refuge for the European Roe deer, which was previously on the brink of extinction in this region.
The presence of unique 'carrilheiro' paths indicates the historical usage of the forest for cattle movement between summer and winter pastures.
Certain sections of the forest remain strictly off-limits to vehicles to prevent habitat fragmentation.
The forest ecosystem acts as a critical natural water filter for the Vilarinho das Furnas reservoir.
Mata de Albergaria is a protected core area within the Peneda-Gerês National Park, representing one of the most important remaining patches of ancient deciduous forest in Portugal. The region is characterized by old-growth stands of pedunculate oak (Quercus robur), which are remnants of the original vegetation cover of the Iberian Peninsula. It functions as a strict biological reserve, restricting human activity to ensure the preservation of its ecosystem. The area contains historical elements including the remains of the Geira, a Roman road that once connected Bracara Augusta to Asturica Augusta. Visitors traverse a landscape defined by mountain streams, granite boulders, and a high concentration of endemic plant species. The forest is a key habitat for the Iberian wolf, the Roe deer, and various birds of prey.

Bring sturdy, waterproof hiking boots as the terrain is uneven and often damp.
Carry all waste out with you, as there are no trash collection facilities within the protected core.
Check the local weather forecast before arrival, as mountain conditions in Gerês can shift rapidly.
Do not attempt to drive through restricted paths that require special authorization, and do not remove any botanical or geological samples.
Access to specific interior paths can be restricted during high fire-risk periods in summer.
Strictly remain on marked trails to protect the forest floor and sensitive vegetation; noise must be kept to a minimum to avoid disturbing wildlife.
