Greater Caucasus
The Greater Caucasus Mountain Range forms the northern border of Georgia. The main roads through the mountain range into Russian territory lead through the Roki Tunnel between Shida Kartli and North Ossetia and the Darial Gorge (in the Georgian region of Khevi). The southern portion of the country is bounded by the Lesser Caucasus Mountains. The Greater Caucasus Mountain Range is much higher in elevation than the Lesser Caucasus Mountains, with the highest peaks rising more than above sea level.
