Su Sterru


Su Sterru: the deepest single-span sinkhole in Europe
Located on the fascinating Golgo Plateau, Su Sterru is one of the most iconic natural landmarks of the Baunei Coast. With its remarkable depth of 280 meters, this impressive karst sinkhole is the deepest single-shaft pit in Europe and attracts visitors and speleology enthusiasts from all over the world.
BETWEEN LEGEND AND NATURE
Shrouded in mystery, Su Sterru is at the center of ancient local legends. According to popular tales, the sinkhole was once inhabited by “Su Scultone,” a serpent-like creature that terrorized the people of Baunei. The construction of the nearby Church of San Pietro is said to have driven away this threat. Today, the sinkhole is home to the Sardinian cave salamander, a rare and harmless amphibian that has become a symbol of this unique natural site.
A RECORD-BREAKING NATURAL MONUMENT
Since 1993, Su Sterru has been officially recognized as a natural monument, and its geological origin is just as fascinating. Formed by centuries of rainwater erosion, this karst chasm is a masterpiece of nature. Its bottom, accessible only to highly trained speleologists, remains a coveted destination for vertical explorations.
AN EXPERIENCE NOT TO MISS
Whether you are passionate about speleology or simply a curious visitor, Su Sterru is an unmissable stop on the Golgo Plateau. Admire the majesty of this immense sinkhole from its edge and take in the mystical atmosphere that surrounds it.
If you have more time, take the opportunity to explore the entire Golgo Plateau, a place filled with natural and historical wonders. Just a short distance from Su Sterru you will find As Piscinas, natural basalt basins that collect rainwater and were once considered sacred places.
