Is Zuddas Cave


The Is Zuddas Cave is part of a complex network of karst cavities located in Monte Meana, in the municipality of Santadi. The embedding rocks date back to around 530 million years ago. The initial part of the Is Zuddas Cave was reached by unknown people already in the early 1960s, through a narrow natural tunnel about 20 meters deep. In 1968 some quarrymen opened an artificial entrance, an alternative to the narrower natural entrance. A few years later, in 1971, various speleological groups resumed their explorations and managed to discover new tunnels, interspersed with a series of hitherto unknown rooms, for an overall length of about 1500 m. In 1985, after the arrangement of a tourist route, the cave was definitively open to the public. One of the main attractions of Is Zuddas is undoubtedly represented by the remarkable variety of speleothems or concretions. Alongside the most common types such as stalactites, stalagmites, and spectacular flows it is possible to observe many others, among which we recall the very thin tubular stalactites, known as straws, the very delicate aragonite needles that cover entire walls, the eccentrics of aragonite, consisting of an indescribable intertwining of filaments that have grown without following the force of gravity, in total disorder, to form pure white skeins of stone.
