In the northeastern part of Folegandros, you will find the renown Chrysospilia.
Chrysospilia is a pretty impressive cave, with its entrance being just a few meters above sea level and actually facing it. The length of the cave is about 300 meters and it is decorated with very beautiful stalactites and stalagmites in various shapes. But what makes Chrysospilia special is the hundreds of ancient names you will see engraved on the walls. Archaeologists believe that Chrysospilia was visited by teenagers from all over Greece under some kind of initiation ceremony. The names' vast majority is male, while in many cases you'll notice that the place of origin is also written.
Access to Chrysospilia is difficult and it depends on the weather. One way to get to Chrysospilia is by stairs. These were made in antiquity and are now called "ellinika skalia" ("Greek stairs"). The cave is also accessible from the sea but not when strong north winds blow.
