Symi was occupied by Italy during the 20th century, a legacy still visible in the neoclassical architecture of the pretty harbour at Gialos. This is a sleepy island that only smaller cruise ships can reach, and the coastline is punctuated by beautiful blue coves and sandy beaches.

The rocky island of Folegandros, named after the son of King Minos, is well off the usual tourist trail thanks to its diminutive size and lack of an airport.
