The entire complex is well worth seeing. It features numerous old mills lined up next to each other. The valley was once covered with mills from top to bottom. Even today, it's still an exciting complex, even though most of it has fallen into disrepair, the structure is still clearly recognizable.

At the end of Praia da Liberdade, near the river, stands the monument dedicated to April 25, 1974 (Estátua do 25 de abril or Estátua da Liberdade), a tribute to the people of Viana who fought for freedom. This sculpture by José Rodrigues was inaugurated on April 25, 1999. Beautiful for photos; the fountains create a small water feature show.

On the banks of the Neiva River, traces of ancient human activities such as mills, sawmills and flax mills that once gave life to the region still remain. Today, this natural setting is home to a rich biodiversity: trout and bream glide through the waters, otters peek out curiously, and in the sky, birds fill the estuary with movement. Among the winged inhabitants, the grey heron, the mallard, the yellow-legged gull and the agile kingfisher stand out.

Belinho Beach stretches for about three kilometres, flanked by a long line of dunes where small wetlands are hidden. The sand is unique, made up of quartzite pebbles of various sizes, which shine in the sun. You can explore the dune landscape on the boardwalk that stretches for several kilometres, crossing a strip of sand that is about 300 metres wide.
