Leh to Tso Kar — Rupshu Plateau High Desert Crossing via Puga Valley Hot Springs
Salt lakes and sulphur vents at 15,000 feet.
Tso Kar — the White Lake — sits at 4,530 metres (14,862 ft) on the Rupshu Plateau, a saline pan that bleaches white at its edges and draws Tibetan nomads with their yak herds each summer. Getting there from Leh means crossing the Tanglang La (5,359 m / 17,582 ft), one of the highest motorable passes in the world, before dropping into the Morey Plains — a sweeping 4,400-metre plateau where kiang (Tibetan wild ass) run across the gravel in packs and the road is whatever the military grader last scraped. The Puga Valley geothermal field steams beside the track — sulphur vents and boiling mud pools at the edge of a high desert that averages less than 100 mm of rainfall per year.
The road is classed Difficult to Expert depending on season and recent maintenance by the Border Roads Organisation. You need a capable 4WD with good ground clearance — locally rented Mahindra Scorpios tackle this, but a stock sedan will not. Altitude sickness is a genuine risk; acclimatise in Leh for at least two full days before heading onto the plateau. The Inner Line Permit (ILP) is mandatory for foreign nationals and must be arranged in Leh — no exceptions, checkpoints enforce it. Best season is June to mid-October; the pass closes with the first heavy snow. Fuel in Leh; carry extra. Cell service disappears at Tanglang La and doesn’t return until you’re near Tso Moriri junction.

Frequently asked questions
Can a stock Mahindra Thar or Gypsy handle this route, or do I need a prepped rig?
A stock high-clearance 4WD like a Thar, Gypsy, or Fortuner can manage this route, but suspension flex and ground clearance matter on the rocky Puga Valley sections and river crossings. Lifted or lightly modified rigs will have more margin. Traction control is helpful but not mandatory — low-range is non-negotiable.
When does the Leh to Tso Kar route actually open and close each year?
The route is generally accessible from mid-June through October. Early June can still have snow on high passes, and post-October conditions deteriorate fast with hard freezes and occasional early snowfall cutting access. July and August are peak window but expect afternoon thunderstorms.
What permits do I need to drive through the Rupshu Plateau to Tso Kar?
Tso Kar and the Rupshu region fall under a Protected Area, so foreign nationals require an Inner Line Permit (ILP) obtained through the LAHDC or authorized agents in Leh. Indian nationals currently do not need a permit for this route but regulations have shifted before — confirm current rules in Leh before departure. Checkpoint stops are real; carry printed copies.
What's the hardest section of this route and what does it actually throw at you?
The Puga Valley approach and the crossings near Sumdo are the crux — loose shale, unmarked tracks, and water crossings that vary from ankle-deep to axle-deep depending on snowmelt. At 15,000+ ft, any mechanical problem or vehicle recovery is physically brutal; altitude hits hard when you're winching or digging. There's no rescue infrastructure out here.
How far is the nearest fuel from Tso Kar, and should I carry extra?
Leh is your last reliable fuel stop — roughly 270 km round trip to Tso Kar. Fuel availability in Korzok (the small settlement near Tso Moriri, not Tso Kar) is inconsistent and not guaranteed. Carry a minimum 20-30 liters extra in a proper jerry can; this is not a route where you gamble on finding a pump.
