The great wealth of this granite plateau are undoubtedly the peat lands accompanying mountain streams, habitat of many species of flora that only grow here. Cyclamen-flowered daffodil, the cross leaved heat, the matgrass and the marsh gentian are some of the species that characterize this rare ecosystem. Some dragonfly species, the european tree frog, western three-toed skink and the blue rock thrush are also frequent on this plateau. The S. Pedro Velho Castle Kopje – geosite from Arouca Geopark – is a residual granitic relief of the Freita mountain, and marks its highest point at 1077 meters. For its altitude, grandeur and position it occupies in the mountains, this point is well visible from practically all the Freita’s plateau and reaches, in a clear day, about half of continental Portugal, from the Gerês mountain to the Estrela mountain.
