Cascades de Polischellu, Natural waterfall system in Corse-du-Sud, France.

The Cascades de Polischellu lie between the Col de Larone and the Col de Bavella in Corse-du-Sud. In the photograph, a thin white stream drops from a notch between large rounded grey rock formations into a pool below, where submerged stones show green and yellow tones through the clear water. A broad rock face rises steeply to the left of the falling water, and a cluster of boulders forms a rounded shoulder to the right.

The waterfall area has been shaped by millennia of water erosion through Mediterranean mountain terrain, forming part of Corsica's geological heritage. The granite formations that define the site today developed over vast timescales through natural processes of water and rock interaction.

The stream that feeds the falls is the Polischellu, and one of six new fly species (Empididae, Clinocerinae) found in Corsica in 1992–93 was collected in this watercourse. Corsica's freshwater invertebrate endemism is among Europe's highest, especially in mountain torrents. Bathers use the rock pools below the falls.

The cascades lie between the Col de Larone and the Col de Bavella, reached from the D268; cars stop on the parking area around a large tree whose trunk grows between two rocks, near the bridge over the river. From there an unmarked path leads through vegetation in a few minutes to a chain of small falls and rock pools. The rounded blocks are warm in spring, but full bathing comes only with the hotter months.

The Polischellu stream, which feeds these falls, yielded one of six new fly species (Empididae, Clinocerinae) found in Corsica in 1992-93. Corsica's freshwater invertebrate endemism is among Europe's highest, and this torrent is one of the mountain streams where it was documented.
