Pakistan
Khunjerab Pass
Yaks graze at 4,693 metres where the Karakoram Highway ends at Earth's highest paved border.
The air thins to a whisper at 4,693 metres. Prayer flags crack in wind that crossed the Pamir before it found you. Yaks graze on tundra grass beside a striped border barrier, indifferent to the fact that Pakistan ends here and China begins. The Karakoram Highway — one of civil engineering's most improbable achievements — reaches its highest point and simply stops.
Khunjerab Pass is the highest paved international border crossing on Earth, joining Pakistan's Gilgit-Baltistan to China's Xinjiang along the Karakoram Highway. It sits inside Khunjerab National Park, established in 1975 to protect the Marco Polo sheep and snow leopards of the upper Karakoram. From Sost — the last Pakistani settlement — the road climbs through increasingly bare terrain, past glacier tongues and scree where marmots whistle from the boulders, to a simple gate marking the frontier at a regulated crossing: visitors stay within the marked areas. The surrounding peaks exceed 7,000 metres, the air holds roughly half the oxygen of sea level, and snow seals the pass from around November to May.
Solo
Standing at the roof of the Karakoram Highway, at a border between civilisations — edge-of-the-world solitude that solo travel is built for.
Couple
The drive up from Passu unfolds like a slow-motion altitude reel — shared silence at 4,693 metres, nothing to do but absorb the enormity.
Friends
A road trip to Earth's highest paved border, stopping for tea and dried apricots along the way — the kind of destination that earns bragging rights.
- The highway climbs from 2,400 metres at Gilgit to 4,693 at the pass — the gain audible in your own breathing.
- Marco Polo sheep — among the world's largest wild sheep, their curled horns spanning well over a metre — graze the protected slopes.
- The pass opens roughly May to November; winter seals the road and the border entirely.
- Across the gate, the land flips instantly to the brown steppe of Chinese Central Asia — the contrast is total.

The trail ends at a 1902 crater; the summit is another ninety minutes with no path.
