Crossroads field guides · Upper Hunza · Karakoram Highway
Khunjerab Pass links Upper Hunza with China’s Xinjiang region at approximately 4,693 metres. A drive to the Pakistani border viewpoint and an international crossing are different journeys. This guide explains the route, altitude, time allowances and operational checks that matter for both.

Where the crossing is
The pass lies north of Sost on the Karakoram Highway, inside the high mountain environment of Khunjerab National Park. On the Chinese side, Tashkurgan is the relevant onward town. The border gate is not a place to cross casually after a sightseeing visit; immigration, customs and approved transport arrangements apply.
The official Salam Pakistan destination entry gives an approximate pass elevation of 4,693 m. Even a short visit reaches a height substantially above Hunza’s inhabited valley bases. Plan for the altitude as well as the kilometres.
The drive through Upper Hunza
Karimabad to Attabad and Passu
The northbound corridor passes Attabad Lake, the lake-side tunnels, Gulmit and the dramatic peaks around Passu. These places deserve time on their own. Combining every viewpoint, village walk and the border in one day usually leaves little flexibility.
Sost and the final ascent
Use Sost to confirm border or park access, vehicle arrangements and supplies. Beyond it, facilities become more limited and the road climbs into open alpine terrain. Carry warm layers even when the valley below feels comfortable.
| Leg | Approximate distance | Time allowance |
|---|---|---|
| Karimabad–Sost | 85–100 km | 2–3 hours |
| Passu–Sost | 35–45 km | About 1 hour |
| Sost–Khunjerab Pass | 80–90 km | 2–3 hours |
These are planning estimates, excluding lengthy sightseeing, entry queues, customs and delays. Reserve a full day from central Hunza and turn back early if weather or access deteriorates.
Year-round policy and actual access
Older guides routinely say the border always closes from December to March. APP reported the move to year-round port operation from December 2024, followed by a formal inauguration in April 2025. That policy change should not be converted into a promise of unrestricted winter tourism.
Snow, clearance work, holidays, port working days and administrative decisions can still interrupt passenger travel. APP’s December 2024 reporting also mentioned weekend closure for the port. Verify the schedule for your intended date, with both sides where crossing is planned. Read the dated policy report.
A national park visit, passenger crossing and freight operation may have different permissions or schedules. Ask specifically about your activity instead of accepting a general statement that “the border is open.”
A viewpoint visit versus an international crossing
| Visit type | What to verify | What not to assume |
|---|---|---|
| Pakistan-side excursion | Park entry, local permissions, road clearance and return daylight | That entry to China is included |
| Pakistan to China crossing | Chinese entry permission, port schedule, transport and onward arrangements | That your private Pakistan vehicle can simply continue |
| China to Pakistan crossing | Pakistani visa, China-side exit procedure, border transport and Sost reception | That clearance finishes at a fixed time |
Keep a buffer night near the crossing and avoid booking a tightly timed onward flight. China and Pakistan use different time zones; confirm which local time appears in all pickup and port instructions. Passport nationality and visa category can affect eligibility.
Altitude, weather and a comfortable visit
Limit strenuous activity at the pass and build the visit after time at lower northern bases. Discuss personal suitability with a travel-health professional if you have relevant health concerns. If someone feels unwell, prioritise returning to a lower elevation and obtaining help over staying for photographs.
Pack a windproof outer layer, warm mid-layer, hat and sun protection. Do not use one Hunza temperature forecast to predict conditions at the pass. Check current weather information and a local road report shortly before setting out.
Keep wildlife at a distance; sightings of ibex or other animals are possibilities, not guaranteed attractions. Carry out waste and follow park rules. For the wider route, use our northern destination guide, mountain geography guide and US visitor visa guide.
Frequently asked questions
Can I visit Khunjerab without entering China?
A Pakistan-side excursion is possible when local access is permitted. It is separate from international crossing procedures.
Is the border still always closed in winter?
The port moved to a year-round operating policy in December 2024. Weather and operating restrictions can still stop your intended visit or crossing.
How high is Khunjerab Pass?
The official destination portal lists approximately 4,693 m. Plan for high altitude even on a short stop.
Can I make it a quick stop on the way to a flight?
Allow generous time and a contingency night. Weather, road access and border processing can disrupt a tight connection.
