Sioni Reservoir

Where Soviet engineering meets mountain stillness

Sioni Reservoir

Sioni Reservoir spreads across the Iori River valley like a forgotten promise, its waters held back by a concrete dam built in the early 1950s, its hydropower station entering service in 1963-1964. The lake serves as a vital irrigation source for the fertile Kakheti plains below, but locals have long claimed it for quieter purposes. On windless mornings, the eastern face of the Greater Caucasus range mirrors perfectly in its surface—Gudauri’s ski slopes visible as ghostly white traces even in summer. Fishermen cast for carp and zander from the dam wall, while shepherds from Sioni village still water their flocks at the shoreline as they have for generations. It is not dramatic; that is precisely its gift.

On the ground See

  • Walk the full length of the dam wall for unobstructed views of the Iori River gorge and distant Tianeti mountains
  • Cast for carp from the eastern shore near the old concrete piers, where locals gather at dawn
  • Drive the unpaved track to the village of Sioni and descend to the water's edge through abandoned Soviet-era orchards

Practical Know before you go

Best visited April–October; the reservoir lies 8km east of the S3 highway near Sioni village, accessible by unpaved road requiring a sturdy vehicle or 30-minute walk from the village.
