The History Of The Grotte Is Zuddas
A 530 million years old cave, Is Zuddas Grotto was created in Mount Meana by the disruptive force of water over time. Within the large underground natural tunnel, there are also three different halls.
During the 1960s, the grotto was used as a quarry to extract marble, while in 1971, the Santadese Speleo Club group began operations to monitor and control the grotto.
In 1985 the cave was finally opened to the public, attracting tourists from all over the world. Since 1990, at Christmas the grotto hosts a beautiful nativity scene in the Sala dell’Organo (Organ Hall).
What’s Inside The Grotte Is Zuddas?
The Is Zuddas grottos are part of an underground cavity complex that passes through Mount Meana, a 240-meter-high hill (that’s 287 feet, in case you are wondering). The entrance to the cave tunnel is close to Santadi, in the lower Sulcis region of Sardinia, which is very famous for its excellent gastronomy, and for the beautiful natural sites.
The tourist route inside the cave is about half a kilometer long (that’s 0.3 miles), and passes through stalactites, stalagmites and impressive formations similar to petrified waterfalls. Over time, some aragonites where formed into three like shapes, giving the Grotte Is Zuddas caves an almost magical atmosphere.
The strange shape of the arogonites is the feature that has made the caves famous worldwide. These aragonites have developed in different directions, defeating the force of gravity and becoming a real scientific and geological mystery that is still being studied to this day.
The Is Zuddas caves also feature three natural halls. The wide and imposing Sala del Teatro (Theatre Hall) is the first one you will see, the one that welcomes the visitors, with stalagmites formed after a landslide.
From the Sala del Teatro the tunnel continues to the Sala Eccentrica (Eccentric Hall), which is particularly striking due to the aforementioned aragonites.
The third hall is the Sala dell’Organo (Organ hall). It takes the name from a column of stalactite and stalagmite that resembles an organ. In this Hall you can admire a unique nativity scene, the union of nature and Giovanni Salidu’s sculptures.

Hello Claudia, I am planning a trip to Sardinia especially to see the cave with the rainbow colours in it. Could you please guide me as to where that is? It looks absolutely magical! Is it the cave of Neptune?
