Altai Plateau Traverse (Ukok Circuit)
Four-nation convergence on Asia's roof
The Ukok Plateau sits at 2,200 meters where four nations converge, a windswept steppe where archaeologists discovered the 2,500-year-old Ice Maiden mummy. This 300-kilometer circuit begins at Kosh-Agach and threads through the UNESCO Quiet Zone, following herder tracks across rolling grasslands broken by glacier-fed streams. The route passes ancient burial mounds and Soviet-era border fortifications while navigating boulder fields that guard approaches to the Tabyn-Bogdo-Ola massif on the Mongolian border.
Difficult rating requires high-clearance 4WD with low-range transfer case for river crossings and loose rock sections. Travel June-September when mountain passes remain snow-free. Fuel in Kosh-Agach and carry 20 liters extra. Border zone permits mandatory from FSB offices in Gorno-Altaysk. Reward comes through complete solitude on one of Asia’s last untouched plateaus, camping under star-filled skies while golden eagles hunt marmots across endless grasslands.

Frequently asked questions
Can a lifted Tacoma or stock Land Cruiser handle the Ukok Circuit?
A stock Land Cruiser 70/80 series or equivalent high-clearance 4WD with low-range is the minimum — this isn't a trail you push with a mild lift and all-terrains. Soft river crossings, boggy plateau sections, and steep loose descents demand proper diff locks or serious traction control, plus a snatch block and recovery gear.
When does the Ukok Plateau actually become driveable each year?
June through September is the realistic window — snow lingers well into late May at 7,500+ ft and the river crossings swell hard with snowmelt in early June. September can close fast if an early storm hits; most experienced drivers target July to mid-August for the safest conditions.
What permits do you need to drive the Ukok Circuit?
You need a border zone permit (погранпропуск) from the FSB because the Ukok Plateau sits in a restricted military border area adjacent to Mongolia, China, and Kazakhstan — apply at least 30-60 days in advance through official FSB channels or a local Altai fixer in Kosh-Agach. Entry into Altai Tavan Bogd National Park also requires a separate park entry fee paid at the checkpoint.
What's the hardest section and what should I actually expect?
The river crossings on the plateau approach — particularly the Ak-Alakha and Kalguty rivers — are the crux; thigh-to-waist deep on foot, fast current, rocky bottom, and no bridges. Beyond that, the plateau surface itself throws deep mud ruts and waterlogged sections that can swallow a wheel unexpectedly, especially after rain.
How far is the nearest fuel from the start, and can I complete the 186-mile route on one tank?
Kosh-Agach is your last reliable fuel stop — fill completely there before heading out. 186 miles of low-range crawling, river crossings, and altitude burns through fuel fast, so carry a minimum 20-30 liters in jerry cans; don't assume one tank gets you back clean.
