The park contains the highest point in the Alentejo region, reaching 1,025 meters above sea level.
It acts as a biogeographical crossroads, hosting both cork oak forests and mountain vegetation atypical for the surrounding Alentejo plains.
The area hosts one of the largest colonies of bats in Europe, sheltered within its limestone caves and abandoned mines.
The medieval village of Marvão sits on a sheer granite cliff within the park boundaries, once serving as a strategic border fortress.
The Serra de São Mamede is home to the last known remnants of certain rare plant species that survived the last glacial period in this microclimate.
Parque Natural da Serra de São Mamede is a protected mountain range in eastern Portugal that features the highest altitude point south of the Tagus River. The landscape consists of a unique transition zone between the Mediterranean climate and the Atlantic influence, resulting in diverse biodiversity. It encompasses several granite and quartzite ridges, including the highest peak, Pico de São Mamede, at 1,025 meters. The area serves as a critical habitat for Iberian lynx and multiple bird of prey species, such as Bonelli's eagles and griffon vultures. Visitors can explore traditional schist and granite architecture in nearby villages like Marvão and Castelo de Vide. The park contains a network of official walking trails ranging from forest paths to rocky ridge ascents. It is officially managed by the Institute for Nature Conservation and Forests (ICNF).

Carry a physical map or offline GPS, as mobile signal is intermittent on the mountain ridges.
Wear sturdy, broken-in hiking boots due to the prevalence of loose quartzite scree on trails.
Pack a windbreaker even in summer, as temperatures drop significantly at higher altitudes compared to the valley floor.
Attempting steep ridge hikes without adequate water supplies or during high-heat alerts, which are common in the region.
Stay on marked trails to protect sensitive flora; observe wildlife from a distance without using flash photography.
