The waterfall is unique for being located inside an inhabited village rather than in a remote natural setting.
The water from the fall historically powered several local grain mills, which have been preserved as historical landmarks.
The limestone rock at the site is part of the Barbagia di Seulo karst plateau, known for its extensive cave systems.
The waterfall flows into the Sa Stiddiosa canyon area further downstream.
The site remains active even during the dry Mediterranean summers due to the high-altitude groundwater reserves in the surrounding mountains.
Cascata di San Valentino is a rare example of a perennial waterfall located directly within the historic center of the village of Sadali in central Sardinia. The waterfall is fed by underground karst springs that emerge through the town's limestone bedrock. The water flows through the village streets and eventually drops over a travertine rock face into a pool below. Unlike most Mediterranean waterfalls that dry up in summer, this site maintains a consistent flow year-round. It is situated adjacent to the 13th-century church of San Valentino, from which it takes its name. The surrounding area features traditional stone architecture and ancient water mills historically powered by the stream. Visitors can access the waterfall by walking through the narrow alleyways of the old town.

Check local weather forecasts, as heavy rainfall can increase the volume and splash area of the waterfall significantly.
Attempting to climb the rock face or entering the pool area, as the slippery travertine surfaces and deep water present safety hazards.
