Predas Rujas Waterfalls, Waterfalls of Sardinia

Predas Rujas Waterfalls, also called Bia Josso or Istrampos de Pedras Rujas, lie in the Bia Josso locality of Santu Lussurgiu, in the Montiferru region of Oristano province, at 535 m above sea level. They are formed by the Rio Bia Josso, which drops in two jumps of about 7 metres each.

The waterfalls are part of a natural landscape that has remained in the region for centuries. Historically, the streams fed by these falls were used by local people for irrigation and daily needs before modern water systems were developed.

The name Predas Rujas comes from Sardinian and means "red stones", referring to the reddish rock around the falls. The falls are also called Bia Josso, after the Rio Bia Josso that forms them, and Istrampos de Pedras Rujas. They lie in the Bia Josso locality of Santu Lussurgiu, in the Montiferru region.

Access is from the town of Santu Lussurgiu, with the final stretch potentially requiring a sturdy vehicle on dirt roads. The walking path from the nearest parking takes about 3.5 km (2 miles) over mountain trails, so visitors should bring water and snacks and wear proper hiking shoes.

The falls are also called Bia Josso, after the Rio Bia Josso that forms them, and Istrampos de Pedras Rujas in Sardinian. They drop about 7 metres in each of two jumps, at 535 m above sea level in the Montiferru.
