Sos Molinos Waterfalls

Cascata di Sos Molinos in Santu Lussurgiu is among the most impressive waterfalls on Sardinia, set on the boundary between Santu Lussurgiu and Bonarcado on the eastern slope of the basalt plateau of Montiferru. The Riu Sos Molinos descends from an altitude of around 440 metres, dropping a total of 30 metres in five successive cascades; the final and largest plunge measures 15 metres. The surrounding valley is so ecologically significant that it has been designated a special area of conservation.

How to get there

The trailhead is along Provincial Road 15 (SP15), connecting Santu Lussurgiu and Bonarcado. A roadside clearing serves as a small car park, from which an old mule track — still bearing occasional fragments of its original stone paving — descends to the valley floor. Allow around one hour for the downhill walk. The path runs beneath a canopy of holm oaks, downy oaks and alders, with dense laurel thickets forming an almost continuous tunnel of green on either side.

What to see at the falls

At the base of the main cascade, the stream spreads into a natural pool fringed by cyclamens, daisies and wild orchids. Standing beside the water is a surviving pre-industrial mill — one of many that once lined the course of the Riu Sos Molinos, which is how the place got its name (molino means mill in Italian). In the pre-industrial era, the steep gradient and high flow rate made the stream ideal for powering grain mills and fulling mills in succession along its banks. The remaining mill is built from local materials that blend naturally into the forest setting.

What sets Sos Molinos apart

Unlike most Sardinian waterfalls, which shrink significantly or dry out in summer, Sos Molinos maintains a strong flow through the warmest months, making it a worthwhile destination in any season.
