Well. I'm thinking mostly of the western part of the country, all the cway from the borders to Albania and North Macedonia to (and including) the Peloponnese. The mountains, all parts of the Pindos [Πίνδος] range (eg. Agrafa [Άγραφα], Tzoumerka [Τζουμέρκα], Gravara [Γκράβαρα]) are full of rain forrests (yes!), lakes, small villages, etc. The Ionian coast line from Preveza [Πρέβεζα] all the way up to the border and a few tens of kilometres with medium-small towns (eg. Vonitsa and Messolongi [Βόνιτσα & Μεσολόγγι]. Of course, one should not forget the Peloponnese, especially the central part and the easyern parts and the Mani [Μάνη] peninsula. Don't get me wrong, what I did not mention is not ugly but, simply, not as unique and the rest. Finally, keep in mind: de gustibus et coloribus non disputandum est.

PS Sorry, this is completely off-topic, but I had to answer!
