Nestled between Turkey, Iran, Russia and the Caspian; the rugged and mountainous Caucasus region, or collectively, the countries of Georgia, Armenia and Azerbaijan is Europe's final frontier.
Once part of the Soviet Union, this far-flung edge of the continent is a true blend of east-meets-west and a complicated mix of different cultures, religions, cuisines and peoples. Over the last decade, this once highly turbulent region has transformed itself into a unique, good value and safe tourist destination.

I have spent the last 10 years exploring the Caucasus and here are the top 10 destinations, beautifully photographed, which are a must on any itinerary for an unforgettable Caucasus adventure.
