Is Zuddas caves, 6km from Santadi on SP70 are open the whole year round.
Although actually 1650m long, the tourist route, made up of a number of impressive chambers, is limited to 500 metres. Each chamber is individual. Among the most attractive is The Organ, with stalagmites that looks like a pipe organ while the walls are covered in the white needle-shaped aragonites. Another, the Theatre Chamber, is imposing and very beautiful while the Room of the Eccentrics is covered with rare, eccentric aragonites, whose horizontal formations cannot be explained by experts.
From November to March two daily tours are provided: one at 12. 00 and one at 16. 00, but visits can be booked for other times too. From April to October tour times are 9. 30-12. 00 and 14. 30-17. Booking is always necessary for groups of at least 30 people.
Is Janas cave, near Sadali runs to about 350m and legend has it that the cave was the home of three janas, mythological beings – half fairies and half witches – and, being Italian, were lovers of good food. Once they cooked pancakes after Lent had started, attracting a fasting monk that was passing by. The monk reproached the three janas for breaking the Lent fast and was, in reply, hanged by them. Divine punishment then turned the three witches into stone, their kitchen utensils and the body of the monk; those forms are identifiable inside the cave today.
You can reach Sadali by road or rail with the Trenino Verde a tourist train that follows a picturesque track through the mountains, valleys, lakes and forests. A bus service then takes travellers from the train station to the cave of Is Janas.
The cave opens every day from 10. 00 to 12. 00 and from 15. 00 to 18. 00. From October to March it is only open on Sunday. The cost of entry is € 4. 00 and includes a guide for the cave and the transport by bus to and from the town’s train station.
Finally, San Giovanni cave, about 3km from Domusnovas, was used long ago as a chapel and now contains a road. What does that say about the current state of Italy, and the world?
