The name Ophir appears several times in the Old Testament, including to designate a land distant from Israel where gold was collected. The gold of Ophir is often referred to as a separate gold, which may be due to the joint expedition of King Solomon and King Hiram (Tyre, Phoenicia) that set sail from the Red Sea and brought back 14 or 15 tons of gold from Ophir (1 Kings 9:26-28; 2 Chronicles 8:17-18). Thus, the Portuguese beach may be related to a new Ophir discovered by the Phoenicians. A famous local legend, the "legend of the horses of Phanus," even claims that "the biblical Ophir" was located in the place of modern Ophir. Source: Wikipedia

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.
