Greece is the prefect place for naturists. Nude bathing is possible almost everywhere. And there are a lot of sexy Russian girls posing for images along the rocks and beaches. Lesbos and Rhodos in particular are two islands famous for the most beautiful nudistic women in the world.
Climbing the rocks and exploring caves is more fun when naked. After all sunbathing alone is boring after the first day, already.
On the bottomline, Greece is on par with Mexico, Costa Rica and Brazil when it comes to nudist beaches and the exploits for bird watchers.
