Nestled in the verdant nature of the Addolì woods, between Barbagia and Ogliastra, on the border between Seulo and Sadali, is a small masterpiece of nature that is a hole, a cave and resurgence with waterfall and lake. Su Stampu de su Turrunu is a unique hole carved into the Jurassic rock of the Tacchi – characteristic steep sided reliefs – by the erosive action of water that flows into a small cave with a stream, su Longufresu, that then drops 16 metres into a pool and finally flows downwards into the valley below.

A karstic phenomenon of uncommon beauty, a sound of a waterfall set in the verdant green that splashes into the pool below, the silvery glimmer of clear water that enlivens the entire area and makes it one of the loveliest natural monuments in all of Sardinia.
