Best Greek island for: Deep-blue seas and wide-open spaces.
This craggy Cycladic island has always attracted loners, hikers, divers and pilgrims, who shuffle up the cliff face to the Monastery of Hozoviotissa, a sliver of white dangling 300 metres above the sea. The water here is a million shades of blue and so startlingly clear you can see every sea urchin lurking on the rocky shore. Even the sage-scented hiking trails are called Blue Paths, because the sea and sky are visible in all directions.
