North from Tbilisi and up though the Caucasus to the Russian border runs the famed Georgian Military Highway, celebrated by poets and feared by military leaders over many long centuries. It has served as an important link between Europe and Asia since ancient times, though it was only after Russia’s annexation of east Georgia in the 19th century and the subsequent improvement of the track for troop movements that it became known as the “Military Highway”. Today it serves as the best route via which we can enjoy the dramatic scenery, crystal-clear air and indescribable grandeur of the mighty Caucasus Mountains.
