Kosh-Agach
The last settlement before Mongolia, Kosh-Agach stretches across the Chuya steppe at nearly 1,800 m altitude. A logistical base for the Ukok Plateau, it offers direct contact with Kazakh culture in South Altai.
Kosh-Agach is a settlement in the Altai Republic, positioned in the Chuya steppe at approximately 2,000 meters altitude, near the Mongolian border. The last inhabited point before the Dyuhtou Pass and Mongolia, it serves as a logistical base for expeditions to the Ukok Plateau and the high valleys of South Altai. The semi-desert landscape, Kazakh yurts and low-angle light make it a distinctive stop in the region.
Quick reference guide

- Access: Chuya Highway (M52), approximately 460 km from Barnaul; last major fuel station before Mongolia.
- Border zone permit: mandatory to approach the Mongolian border — request in advance from the FSB.
- Recommended duration: half a day to one day as a stopover; several days if using as a base for the Ukok Plateau.
What to see
The Chuya steppe extends as far as the eye can see, framed by the snow-capped ridges of Chuiskiy Belok and Kuraiskiy Belok. The settlement itself is modest: a few streets, a local market frequented by Kazakh herders, and yurts on the outskirts. The Chuya River flows through the valley before joining the Katun further north.
History and context
Kosh-Agach roughly means "double tree" in Turkic. The settlement developed as a trading post on the caravan route linking Russie to Mongolia and China. The population is predominantly Kazakh, descendants of nomadic herders who roamed these steppes for centuries. The region long remained a sensitive military zone due to its border position.
Highlights of the visit
The Chuya steppe
A rare semi-desert landscape in Russie, the Chuya steppe offers unusual light and dryness for Altai. Ochre and beige colors contrast with white peaks in the background. It is one of the few places in Russie where mirage phenomena can be observed in hot weather.
The local market
Kosh-Agach's market reflects the region's Kazakh culture: fermented dairy products, dried meat, felt craftswork. It's a direct point of contact with the daily life of valley herders.
Gateway to the Ukok Plateau
Kosh-Agach is the usual starting point for reaching the Ukok Plateau, a UNESCO World Heritage site, where archaeological excavations have uncovered exceptionally well-preserved Scythian tombs in the permafrost.
Photography tips
Morning and evening light is particularly favorable: the dry steppe air provides rare clarity for snow-capped peaks. Yurts on the settlement's outskirts offer interesting foreground with ridges in the background. Always ask permission before photographing residents or their dwellings.
Location and access
Kosh-Agach sits at the southern end of the Chuya Highway (M52), approximately 460 km from Barnaul and about one hundred kilometers from Gorno-Altaysk by road. The road is asphalt all the way to the settlement. No direct air connections; the drive from Gorno-Altaysk takes several hours depending on conditions. Disabled access is limited outside the settlement itself.
