In the well-equipped Parque de Espinhel, there are walkways over the waters of Pateira de Fermentelos that lead us to two wooden viewpoints, whose structures are reminiscent of a bandstand. From here we can enjoy wide views over Pateira, as well as the village that gives it its name, Fermentelos, on the opposite bank. On the edge of the lagoon, in addition to reeds and bunho, we find dense swampy willows, a refuge and habitat for numerous species of fauna, among which the avifauna stands out. In this place it is common to observe Moorhens (Galinula chloropus) and Coots (Fulica atra). The attentive observer finds an abundant and diversified biological diversity throughout the year, partly due to the occurrence of summer and winter migratory species, such as: Garçote (Ixobrychus minutus), Red Heron (Ardea purpurea), Stilt (Himantopus himantopus), Black (Nycticorax nycticorax), Osprey (Pandion haliaetus), Saffron Eagle (Circus aeruginosus), Black Ibis (Plagadis falcinellus), Spoonbill (Platalea leucorodia), as well as dozens of passerines! In the vicinity of the park, red sandstones from the tertiary period (Eirol sandstones) can be seen in the disused quarry. Source: Great Route of Ria de Aveiro
