Mkinvartsveri is an extinct volcano whose last eruption is supposed to have happened in the Middle Pleistocene, sometime between 2,580,000 and 11,700 years ago.
A number of glaciers come down from it, including Suatisi, Mna, Ortsveri, and Devdaraki. The fastest river in Georgia, the Tergi, has its source there as well.
Kazbegi is especially attractive for mountaineers and rock climbers, but you don’t have to be a professional athlete to get to it's top. What you do need is good physical preparedness, a well-chosen time, the right equipment and most of all - a professional guide.
There are two classic routes climbing up to the top of Kazbegi and the best time for ascending is from the second half of summer to the middle of September, when the snow cover is less and the weather is mostly sunny.
Once you have reached the peak, standing above the clouds in an infinite expanse, you will gaze out over a breathtaking view that will make all of the sweat and aches worth it.
