Across Papafragas you will see a rare creation of nature 0.8-0.7 million years of age. Thousands of standing pentagonal and hexagonal columns, with diagonals of 20-30cm are formed on the andesitic rock and make the tourists, who circumnavigate them, pull out their cameras hastily to take pictures. The islets are permanently accompanied by seagulls. On Glaronisia a climbing field has been created as well.
