Khunjerab Pass Border Crossing Guide 2026 — Pakistan to China Overland
The Khunjerab Pass border crossing is the highest paved international border in the world and the most dramatic overland gateway between South Asia and China. Our Xinjiang travel guide covers the whole region, but this page focuses on the practical mechanics of getting across on your own. At 4,693 metres the pass links Sost in Pakistan’s Gilgit-Baltistan with Tashkurgan County in China’s Kashgar prefecture, carrying the legendary Karakoram Highway over the roof of the Himalayas. For independent travelers who want to feel the road rather than skim over it at 10,000 metres, this is the crossing that earns its reputation.
Why Cross at Khunjerab
For independent travelers the appeal is hard to overstate. The Karakoram Highway is one of the great road journeys on earth, threading past the Nagar valleys, the Rakaposhi viewpoint, the Hopar and Batura glaciers, and finally the wind-scoured saddle at Khunjerab. On the Chinese side the road drops through the Pamir Plateau, past Karakul Lake and Muztagh Ata, toward the Silk Road melting pot of Kashgar. Crossing here is not a formality; it is the trip.
It is also the only legal land border between Pakistan and China. If you are coming from Islamabad or Gilgit and want to reach Xinjiang under your own steam, Khunjerab is the route, and the sense of arrival on the Chinese side — after days of switchbacks, glacier streams, and army checkpoints — is genuinely unlike any airport landing.
The Route: Distances and Driving Times
Plan the drive in legs, because altitude and checkpoints make it slow. Distances below are road distances measured along the KKH and the Chinese G314.
| Leg | Distance | Drive time | Notes |
|---|---|---|---|
| Islamabad – Gilgit | ~480 km | 10–12 h | Mostly paved; landslides common Jul–Aug |
| Gilgit – Sost (Pak border post) | ~220 km | 5–6 h | Attabad Lake boat bypass may add time |
| Sost – Khunjerab Pass top | ~84 km | 2–3 h | Steep climb to 4,693 m |
| Khunjerab Pass – Tashkurgan | ~130 km | 2.5–3 h | Chinese immigration at the port |
| Tashkurgan – Kashgar | ~290 km | 4–5 h | G314, paved, police checks |
| Kashgar – Khunjerab Pass (total) | ~420 km | 7–8 h | Useful for a same-day return charter |
Most travelers break the Pakistani side in Gilgit or Hunza (Karimabad) and the Chinese side in Tashkurgan before pushing on to Kashgar. Do not try to do Sost–Kashgar in one day; the border closes before you would arrive, and the high-altitude drive is punishing after a night at the pass.
Border Crossing Procedure
Pakistan Side (Sost)
All passengers clear Pakistani immigration and customs in Sost, not at the pass. The Sost dry port processes exits in the morning; you then board a Pakistan-side shuttle or your own vehicle for the 84 km climb. Pakistani officials stamp you out, and your transport waits at the zero point while you walk or ride the short shuttle across no-man’s-land to the Chinese facility. Budget the whole Sost formality at two to three hours in peak season, because several busloads arrive together and the windows are not fast.
China Side (Khunjerab Port)
The Chinese port sits a few kilometres below the actual saddle. Here you present your passport, visa, and — for foreign nationals continuing into Tashkurgan — your aliens’ travel permit (see below). Chinese immigration is efficient but slow during peak season (June–September), when the queue can run past lunch. Once cleared, vehicles continue down the G314 past the Karakul Lake turn-off and the Bulunkou checkpoint toward Tashkurgan.
Documents and Visas You Need
- Passport valid at least six months beyond entry.
- Chinese visa obtained in advance (or an eligible visa-free / 240-hour transit arrangement if your itinerary qualifies). Pakistani nationals and most others require a standard tourist (L) visa.
- Pakistani visa for the exit direction, plus any Pakistani re-entry permit if you plan to return.
- Vehicle documents if driving your own car: passport, vehicle registration, and a Carnet de Passages en Douane (a temporary import permit). Motorbikes likewise need a carnet, and a few countries’ riders also need a driving permit translation.
- Aliens’ Travel Permit (外国人旅行证) if you are a foreign national heading into Tashkurgan County — applied for at the Kashgar Public Security Bureau, usually through your hotel or a local agent. The Khunjerab port itself issues entry, but the permit lets you legally stay in the border county.
Best Season and Opening Hours
The pass is open roughly 1 May to 31 December. It closes for winter (January–April) because snow at 4,693 m makes the road impassable. Even in season, aim for May–June or September–October to avoid both the July–August monsoon landslides on the Pakistan side and the heaviest crowds on the Chinese side.
| Side | Opening window | Processing hours |
|---|---|---|
| Pakistan (Sost) | 1 May – 31 Dec | ~09:00–17:00 PKT |
| China (Khunjerab Port) | 1 May – 31 Dec | ~10:30–18:30 (UTC+6) |
Hours shift a little year to year, so confirm with your transport operator the week before you cross. The border does not run a night shift; if you are not through by late afternoon you sleep in Sost or Tashkurgan.
What to Expect on the Chinese Side After Crossing
Once cleared, the G314 is paved and well maintained but high. You pass the turn-off to Karakul Lake (worth a night at a yurt stay if your permit allows), then the Bulunkou police checkpoint, then down into Tashkurgan at about 3,100 m. Fuel is available in Tashkurgan and again in Kashgar; there is nothing between the port and Tashkurgan except a military canteen. Chinese SIM cards activate after immigration — buy one at the port shop or in Tashkurgan — and the first real cash machine is in Tashkurgan town.
Cycling and Motorbiking the KKH
The Karakoram Highway is a bucket-list ride, but the Pakistan side demands a carnet for motorbikes and a support plan for the Attabad Lake section, where a boat ferry carries riders around a 2010 landslide that drowned the old road. On the Chinese side, cyclists clear the same immigration and must arrange a pickup or ride the G314 down; wild camping near the border is not permitted. Build buffer days: a blown tire outside Sost or a closed pass in early May can stall a tightly planned ride by a week.
Practical Tips
- Altitude: The pass is at 4,693 m. Spend a night in Sost (around 2,800 m) or Tashkurgan (around 3,100 m) to acclimatise. Headache, dizziness, and lost appetite are common; diamox and slow movement help, and descend if symptoms worsen.
- Money: Pakistani rupees on the south side, Chinese yuan on the north. There is no exchange at the pass. Carry enough PKR for Gilgit–Sost and enough RMB for the Xinjiang side before you cross.
- Transport options: In season, tour operators in Sost and Kashgar run through-buses (Sost–Tashkurgan, roughly ¥200–350 arranged locally). A private 4×4 with driver from Kashgar to the pass and back runs about ¥1,500–2,500. Walk-up rides are rare, so pre-book.
- Connectivity: Pakistani SIMs stop working past Sost; Chinese SIMs activate after immigration. Download offline maps for both sides before you leave coverage, and tell someone your crossing date.
- Food and fuel: Fuel is available in Gilgit, Sost, Tashkurgan, and Kashgar. Pack water and snacks for the high stretch; the only shelter between Sost and the port is a military canteen that does not serve tourists.
- Documents copy: Carry printed photocopies of your visa, carnet, and permit. Signal and translation help are scarce at 4,700 m, and a paper copy settles most checkpoint questions faster than a phone screen.
Pakistan Side Logistics: Gilgit to Sost
Most overlanders treat Gilgit as the last real city before the climb. From Gilgit, Natco and PTDC buses run to Sost (around 5–6 hours, ¥300–500 equivalent in PKR), and shared 4x4s fill faster if you are short on time. The one wrinkle is Attabad Lake, where a 2010 landslide drowned 24 km of the KKH; a scheduled boat ferry carries vehicles and passengers around the gap, adding 45–90 minutes and a separate ticket. Confirm the ferry is running before you commit, because a closure reroutes you onto a long, rough detour. Fuel, cash, and a SIM top-up are all easiest in Gilgit; Sost has one ATM that often runs dry, so arrive with enough rupees for the border and a buffer.
A Sample Three-Day Crossing Plan
- Day 1: Gilgit to Sost (5–6 h). Sleep in Sost at ~2,800 m to acclimatise; sort Pakistani exit formalities the next morning.
- Day 2: Clear Sost immigration, ride the 84 km to the pass, cross no-man’s-land, clear Chinese immigration. Descend to Tashkurgan (~3 h) and sleep there at ~3,100 m.
- Day 3: Tashkurgan to Kashgar (4–5 h) via Karakul Lake if your permit allows, arriving in time for the old-town dinner rush.
This pace leaves slack for a delayed ferry or a slow queue. Tightening it to two days is possible in shoulder season but leaves no room for altitude or weather.
Safety and Road Conditions
The KKH is paved but exposed: rockfall after rain, frozen patches near the pass in May and October, and the occasional closed stretch for military convoys. Drive in daylight only, keep a full tank, and tell your guesthouse your plan. The border regions are secure but militarised; photographcheckpoints and bridges are off-limits, and a polite “no photos” from a soldier is not negotiable. Travel insurance that covers evacuation above 4,000 m is worth buying before you leave home.
Photography, Culture, and Etiquette on the KKH
The Karakoram Highway passes through living villages, not a museum. Ask before photographing people, especially women and elders in the Hunza and Pamir communities, and a smile plus a raised camera usually earns a nod. The Pakistani side is conservatively dressed; the Chinese Pamir is more relaxed but still respects local Tajik custom. Carry small notes for roadside chai stops — hospitality is genuine, but a few rupees or yuan for a refill is polite. The landscapes need no permission: the Passu conical peaks, the Attabad turquoise water, and the first glimpse of Muztagh Ata from the G314 are among the most photogenic frames in Asia. Shoot in the early morning on the Chinese side, when the light rakes across the glaciers and the checkpoints are quiet.
