Dariali Gorge: the mythic pass between Georgia and the Caucasus
Rock walls rise up to 1,800 metres on both sides of the narrow canyon. The Terek River, green and furious, winds between granite boulders that could crush it. This is Dariali Gorge, the most impressive natural pass of the Greater Caucasus, through which Alexander the Great, Mongol armies and hordes of Silk Road traders have passed.
Geography and history: the pass between two worlds
Dariali forms part of the Georgian Military Highway, the ancient route linking Tbilisi with Vladikavkaz (Russia) through the passes of the Greater Caucasus. The gorge has been a strategic control point for millennia: the Romans knew it as "Porta Caucasica" or "Porta Caspica", and it appears under those names in the chronicles of Ptolemy and Strabo.
The geological formations of the gorge are extraordinary: igneous rocks of volcanic origin that the river has been cutting for millions of years to create this natural corridor barely 100–200 metres wide at its narrowest points.
What to see in Dariali Gorge
- The vertical walls of basalt and granite looming over the road
- The Terek River in its most furious and spectacular course
- The Dariali hydroelectric plant (modern, integrated into the landscape)
- Natural viewpoints with views towards Mount Kazbek to the south
How to visit Dariali Gorge
Dariali is crossed via the Georgian Military Highway on the route to Kazbegi and Gergeti Trinity Church. Most travellers see it from the car or bus. To appreciate it better, stop at the designated viewpoints and go down to the bank of the Terek if you can. Organised tours from Tbilisi to Kazbegi include stops at the gorge.
Frequently asked questions
Is it possible to hike in Dariali Gorge?
There are trails along the Terek River through the gorge, though space is limited by the road and vertical walls. Most trekking in the area takes place in the side valleys higher up, towards Devdoraki Glacier.
What other names does Dariali Gorge have?
The Romans called it Porta Caucasica or Porta Caspica (Gate of the Caucasus or Caspian Gate). In some medieval sources it appears as the "Gates of Alexander", a reference to the legend that Alexander the Great built an iron gate here to contain the barbarians of the north.
Is the Dariali road open year-round?
The Georgian Military Highway through Dariali can close temporarily in winter due to snowfall or avalanches. It is generally open and fully safe from May to November. In winter, check the road conditions before setting out.
