Discover Sardinia's ancient fossils and geology at the Duidduru geosite with a guided tour, including insights into Miocene environments and seismic evidence.
The Duidduru geosite in Sardinia offers a fascinating glimpse into the island’s geological and paleontological past, with an entry ticket costing only $3.96 per person. This one-hour guided tour takes visitors through an open-air museum featuring Miocene fossils and striking geological formations. The tour is suitable for those interested in earth sciences, fossils, and Sardinian history, providing both educational value and stunning scenery. The site is wheelchair accessible and comes as a private group experience, making it ideal for those seeking a personalized, in-depth exploration.
While the visit lasts about one hour, the site’s significant fossil finds and striking stratigraphy make it a worthwhile stop. The tour includes a guided explanation by knowledgeable guides in English or Italian, ensuring a clear understanding of the site’s importance. The price point makes this an accessible outing, especially when combined with nearby attractions such as the Museum PARC and Giara Park.


Located in the territory of Genoni, the Duidduru geosite was discovered in the 1980s and holds exceptional geological and paleontological significance. Its designation as an outdoor museum means visitors can walk among stratified layers of ancient deposits and see fossils in their natural setting. The site is particularly valuable because it features marine fossils from the Miocene period, which can still be related to species that live in modern shallow tropical waters.
What makes Duidduru especially interesting is the wealth of fossils, which have been carefully studied and cleaned by paleontologists from the Superintendence for Archaeological Heritage of Sassari and Nuoro. The fossils are displayed in the P.AR.C exhibition hall, giving visitors a chance to examine artifacts from the site up close.
The stratigraphy of Duidduru reveals a fossilized seafloor, illustrating seafloor conditions from the Miocene era. Visitors encounter a shoal of turritellas, which marks the confluence of sea and river environments that created a lagoon during that time. The geological formations include evidence of ancient seismic activity, such as an exposed fault and Neptunian strands, which show that Sardinia experienced a significant earthquake about 5 million years ago.
These features are not only scientifically interesting but also visually striking, providing a visual history of the island’s geological shifts. The layered stratigraphy and fossil deposits illustrate the dynamic changes Sardinia underwent millions of years ago, making it a prime site for understanding the island’s geological evolution.

The guides lead visitors through the open-air museum, explaining the geological features, fossil preservation, and the scientific studies carried out on site. The fossilized artifacts are excellently preserved thanks to the sandstone, allowing detailed examination of marine life forms from the Miocene.
The guided tour lasts approximately one hour, during which visitors can admire the fossil-rich layers, observe the faults and strands, and understand how these formations tell the story of Sardinia’s past environment. The experience is designed to be educational yet accessible, making complex geological processes understandable for laypersons and enthusiasts alike.

The Duidduru geosite functions as a large-scale outdoor exhibit of Sardinia’s geological history, offering multiple points of interest along a walkable route. The stratigraphic layers and fossilized artifacts form a visual narrative of the Miocene epoch, illustrating marine environments and seismic activity that shaped the island.
This open-air aspect means visitors should wear comfortable shoes and a hat during summer. The site’s interpretive features help visitors connect the geological formations with the scientific studies that have been conducted there, emphasizing the site’s scientific importance.
More Great Tours NearbyAccess to the Duidduru geosite is straightforward, with guided tours available that include the entrance fee. The price of $3.96 per person makes it an attractive stop for those exploring Sardinia’s natural and scientific attractions.

Visitors should consider wearing comfortable shoes and a hat in summer, due to the outdoor nature of the site. The tour is not suitable for people with back problems or wheelchair users, so plan accordingly if accessibility is a concern.
The geosite pairs well with visits to the Museum PARC, where fossils and geological exhibits are curated, or the Giara Park, famous for its wild horses and scenic landscapes. Many visitors appreciate the opportunity to expand their understanding of Sardinia’s natural history by visiting these complementary sites.
In particular, the combination allows for a full day of exploring Sardinia’s diverse natural environment, from fossil-rich outcrops to mountain landscapes and local wildlife.
The main strengths of this tour include its affordability, scientific depth, and accessibility as a private experience. The guided explanations ensure a clear understanding of geological features, and the site’s preserved fossils provide tangible evidence of Sardinia’s Miocene marine ecosystems.
However, the one-hour duration is quite short, making it best suited for visitors who want a focused and educational experience. It is not suitable for those with mobility issues or for travelers seeking a longer, more immersive visit. Despite this, the unique fossils and seismic evidence make it a notable stop for anyone interested in earth sciences or natural history.

The Duidduru geosite offers an affordable and insightful look at Sardinia’s geological past through an outdoor museum setting. With a guided tour lasting about one hour, visitors gain access to well-preserved Miocene fossils, stratigraphy, and geological features that reveal ancient marine environments and seismic activity.
