Gobi Desert Trans-Altai Crossing — Bayankhongor to Khövd via the Mongol Altai Desert Spine
No road. No service. Pure Gobi.
There is no road from Bayankhongor to Khövd. There are tracks — braided, contradictory, and sometimes completely absent across the gravel plains of the Gobi-Altai. This crossing covers roughly 700 km west through Bayankhongor and Gobi-Altai aimags, crossing the Mongol Altai Range via passes that top 2,800 m before descending into the Zavkhan River basin. Key waypoints include the ghost-camel country around Biger Sum, the Tsagaan Bogd massif looming to the south, and the unmarked ford of the Buyant River outside Khövd that has swallowed careless expeditions whole. Navigation is GPS and paper map — tracks diverge constantly and damp weather turns the clay flats into a skating rink.
This is expedition-grade overlanding. Solo travel is genuinely reckless; minimum two-vehicle convoy with full overlanding fit-out: long-range fuel tanks (500+ km range), dual spares, hi-lift, sand boards, and satellite communicator. Mongolian border zone permits are required in certain western aimags — arrange through a Ulaanbaatar travel agency before departure. Best window is late June through mid-September; outside that, snow closes the passes and river levels are unpredictable. Fuel in Bayankhongor and Khövd; nothing reliable between. The payoff is raw Central Asian wilderness that most overlanders will never see.

Frequently asked questions
Can a lifted Tacoma or Land Cruiser 80 handle this route, or do I need a purpose-built expedition rig?
A well-built Land Cruiser 70/80 or Tacoma with a snorkel, high-clearance suspension, and reinforced underbody protection can run it — but marginal builds get eaten alive out here. Long-range fuel capacity (minimum 400+ mile range) and a full recovery kit including hi-lift, traction boards, and a winch are non-negotiable, not optional.
Is the route passable in late May or early October, or is the June–September window strict?
Late May is genuinely risky — snowmelt swells the river crossings and high passes in the Mongol Altai can still be blocked by snow. October brings early freezes and dramatically shortened daylight. June–September is the real window; push those boundaries and you're gambling against weather that moves fast and doesn't care.
What permits do I need to drive this route and how do I get them?
Foreign-registered vehicles entering Mongolia require a vehicle import permit and a standard tourist visa; the route also passes through or near protected buffer zones administered by the Mongolia Ministry of Nature and Environment, which may require additional nature reserve entry permits obtained in Ulaanbaatar before departure. Trying to sort this in Bayankhongor is possible but unreliable — handle paperwork in UB.
What's the hardest section of the route and what makes it serious?
The Mongol Altai high passes between the mid-route desert basin and the approach to Khövd are the crux — loose scree climbs above 9,000 feet with no defined track, severe off-camber exposure, and river fords with no scouting reference points. Navigation collapses to compass headings and terrain reading; if you get stuck or high-centered here, the nearest help is measured in days, not hours.
How do I manage fuel across 435 miles with no towns or stations on route?
There are no fuel sources between Bayankhongor and the outskirts of Khövd — 435 miles of zero resupply. You need to carry all fuel from Bayankhongor, factoring in the brutal fuel consumption of deep sand, river crossings, and high-altitude pass climbing; most experienced crews run 50–80 liters of jerry cans on top of a full primary tank. Calculate your rig's worst-case consumption, not average.
