The name 'Su Stampu' translates to 'The Hole' in the local Sardinian language.
The geological structure is classified as a 'karst window,' formed by the collapse of a cave roof combined with active stream erosion.
The site remains active, with the waterfall continuously shaping the limestone floor of the cavity.
It is situated within the Barbagia di Seulo region, an area characterized by deep canyons and dense Mediterranean scrub.
The internal pool remains fed by the perennial stream, creating a distinct microclimate within the cavern.
Su Stampu de su Túrrunu is a rare karst phenomenon where a river waterfall has carved a vertical hole into a cave chamber, creating a unique natural skylight. Located in the Seulo territory of Sardinia, the site features a 15-meter waterfall that cascades through a circular opening in the ceiling of the cavern. The cavity is formed by the active erosion of the Funtana Cungiada stream against the limestone rock. It acts as a sinkhole, allowing sunlight to illuminate the interior chamber and its small pool. The site is a protected natural monument accessible via a forested trail system.
The elevated vantage point at the rim of the sinkhole provides a clear view of the waterfall descending into the light-filled cavern.
Wear waterproof hiking boots with excellent grip, as the area surrounding the waterfall is perpetually damp and slippery.
Bring a trekking pole to assist with the steep, uneven descent into the canyon.
Check the local weather forecast, as heavy rainfall can make the trail hazardous and the water flow unpredictable.
Do not attempt the hike during or immediately after heavy rain due to the risk of slippery terrain and sudden increases in water volume.
None
Respect the fragile karst ecosystem by staying strictly on marked paths and avoiding any contact with the cave walls or mineral deposits.
