Istrampu de Capu Nieddu

Istrampu de Capu Nieddu in Cuglieri is one of the rarest natural phenomena not just in Sardinia but in all of Italy: a waterfall whose waters fall directly into the sea. The Rio Salighes drops 40 metres off the basalt clifftop straight into the Sardinian Sea, from a natural coastal amphitheatre carved into the high coast between the bay of S'Archittu and the Marina of Tresnuraghes, in the historical region of Montiferru.

Why is this waterfall unique?

Cabu Nieddu exists because of a geological peculiarity: the Rio Salighes flows across the hard basalt surface of the Campeda plateau all the way to the coastline because, over thousands of years, the river never carved itself an underground channel through the rock. The result is extraordinary — the river literally runs off the cliff edge and plunges into the sea from a height of 40 metres. Places like this can be counted on the fingers of one hand across the whole of Europe.

When to visit and how to see it best

Cabu Nieddu is not a year-round waterfall. It flows typically from November to May — the wetter the winter, the more powerful the spring display. In summer, the river dries up. The best viewpoint is from the water: boat tours offering a view of the waterfall depart from Santa Caterina di Pittinurri, Bosa, and Oristano. From the sea, the waterfall appears in full scale against the basalt cliffs and green slopes of the Montiferru massif — a setting frequently compared to the Irish Cliffs of Moher. Looking north from the boat, the headland of Capo Marargiu is visible, home to nesting griffon vultures; to the south lie Capo Mannu and the small island of Mal di Ventre.

What surrounds the waterfall?

The cliffs and slopes around Cabu Nieddu are covered in holm oaks, chestnut trees and strawberry trees, with wild roses, hawthorn and broom growing between the rocks. The scents of thyme and helichrysum accompany every boat excursion. Nearby stands the Spanish watchtower of Capo Nieddu — a remnant of the coastal defence system — and Punta Foghe, guarded by another ancient tower.
