Sa Spendula, Natural waterfall in Villacidro, Italy.

Sa Spendula is a waterfall formed by the Coxinas torrent, which later takes the name Rio Seddanus, near Villacidro. It drops in three successive leaps totaling about 60 meters, and can only be seen from autumn to spring, as it dries up from late spring onward.

The waterfall's documented history centres on 17 May 1882, when Gabriele D'Annunzio walked to the site during his stay in Sardinia and wrote the poem Sa Spendula that same evening. The poem was published on 21 May 1882 in Il Capitan Fracassa, the satirical literary journal founded in Rome in 1880 by Gandolin. The sources record no earlier occupation of the site.

The name comes from the Sardinian word spèndula, meaning "waterfall". In May 1882 Gabriele D'Annunzio walked to the falls at Villacidro and that same evening wrote a poem titled Sa Spendula, published on 21 May 1882 in the Roman literary and satirical paper Il Capitan Fracassa, founded in 1880 by Gandolin.

The site is reached by a short walking path from the parking area on Via Sa Spendula, northwest of Villacidro. The valley is damp and shaded, so sturdy footwear and care on wet surfaces are advisable.

The waterfall drops about 60 metres in total across three jumps, formed by the Coxinas stream, which further downstream takes the name Rio Seddanus. In May 1882 Gabriele D'Annunzio visited the site and wrote a poem titled "Sa Spendula" the same evening; it appeared in the Rome journal Il Capitan Fracassa on 21 May 1882.
