Khunjerab Pass to Sost Circuit
World's highest border crossing in the Karakoram
At 4,693 meters, Khunjerab Pass marks Pakistan’s border with China and the highest point on the Karakoram Highway. This circuit loops from the border post down through Sost, passing through landscapes that shift from barren high-altitude desert to green Hunza valleys. The route follows ancient Silk Road trading paths, with the Khunjerab River cutting deep gorges through granite peaks. Watch for Marco Polo sheep and snow leopards in Khunjerab National Park, while altitude sickness becomes a real concern above 4,000 meters.
This is serious high-altitude driving requiring acclimatization and mechanical preparation. Stock 4WD handles the graded gravel road, but carry spare parts, extra fuel, and emergency gear. The pass closes October through April due to snow. Permits are required for the national park section. The reward is standing at one of the world’s most remote border crossings, surrounded by 7,000-meter peaks and the raw silence of the Karakoram.

Frequently asked questions
Can a stock Land Cruiser or Patrol handle this route, or do I need a lifted build?
A stock high-clearance 4WD like a Land Cruiser 70 or Patrol is the minimum — this is gravel and rocky switchbacks, not rock crawling. Suspension lifts help with washboard comfort but aren't required. What matters more is a reliable engine that won't choke at 15,396 ft.
When does the Khunjerab Pass actually open and close each year?
The pass typically opens late April or May and closes by late October or early November, but June through September is the only window you can count on for stable conditions. Snow can shut it down without warning outside that window — confirm current status with the Sost Dry Port authorities before you roll.
What permits do I need to drive this route and cross into Pakistan from China?
You need a valid Pakistan visa, and foreign nationals must obtain a No Objection Certificate (NOC) for travel in Gilgit-Baltistan — apply through the Ministry of Interior before your trip. At the border itself, vehicle documentation, carnet de passage, and passport checks are done at both the Chinese and Pakistani checkposts at Khunjerab. Expect additional security registration in Sost.
What's the hardest section of this route and what should I actually be ready for?
The descent from the 15,396 ft summit down through the Khunjerab National Park section is the most demanding — loose gravel, steep grades, and altitude-impaired judgment are the real hazards. Brake fade on the descent is a legitimate concern if you're riding them hard; engine braking is your friend. AMS (acute mountain sickness) hits fast at this elevation, especially if you haven't acclimatized in Sost or Gilgit first.
Is there any fuel or water available between the border and Sost, or do I need to carry everything?
There is no fuel between the Khunjerab checkpost and Sost — carry enough for the full 45 miles plus a reserve, as the gravel and altitude hit fuel economy hard. Water from streams exists along the route but must be treated; bring your own for the drive. Sost has basic fuel, food, and accommodation once you're down.
