Karakoram Highway — Gilgit to Sost via Hunza Valley and Passu Glacier
Hunza Valley to the roof — the KKH at its wildest.
The Karakoram Highway between Gilgit and Sost is the raw, mountain-country heart of the KKH — the road built on broken bones and blasting powder through some of the most geologically violent terrain on the planet. From Gilgit heading north, Rakaposhi (7,788m) dominates the eastern skyline before the valley narrows into Hunza, where Baltit Fort clings to a cliff above Karimabad. Past Gulmit, the Passu Cones — those impossibly steep cathedral spires — rise straight off the valley floor. Beyond Passu you hit the Attabad Lake section, forced into existence by the 2010 landslide that buried the original road under 100 metres of water. The tunnel bypass opened in 2015 but the whole corridor is subject to ongoing rockfall, especially through the Batura Glacier toe crossings before Sost.
Most of this segment runs on paved highway but don’t let that fool you — rockfall, washed-out sections, and sudden road closures from fresh slides are routine from July through August (monsoon fringe). The KKH is accessible to standard 2WD vehicles in good conditions but a high-clearance 4WD gives you options when the road goes bad. Fuel up in Gilgit and Karimabad; Sost has basic supplies. The Sost dry port is the last stop before the Khunjerab Pass China border. Best season is May through October. NATCO buses run the route if you want to leave the vehicle behind for a day.

Frequently asked questions
Do I need a 4WD vehicle for the Gilgit to Sost stretch of the KKH?
A standard 4WD is recommended but not always mandatory — locals run this road in 2WD pickups daily. That said, sections near Passu and above Gulmit involve loose gravel, washouts, and steep camber where low-range traction genuinely helps, especially after rain or early in the season when the road hasn't been graded.
When does the KKH between Gilgit and Sost close for winter?
The road typically stays passable May through October. By November, snow and ice hit the higher sections hard and landslide risk spikes — the stretch near Passu Glacier is especially vulnerable. Some years it closes earlier; always check current conditions with the NHA or locals in Gilgit before you go.
Do I need a permit to drive the KKH through Hunza Valley to Sost?
Foreign nationals need a valid Pakistani visa and a NATCO or local transport registration if using a foreign-plated vehicle — check with Pakistani consular services and the Gilgit-Baltistan government before entry. There's a border checkpoint at Sost since it's the last stop before the Khunjerab Pass into China, so carry all vehicle and identity documents.
What's the hardest section of this route and what should I actually expect?
The stretch between Gulmit and Passu is where things get real — narrow shelves cut into cliff faces, active rockfall zones, and sections where the road has partially slid away and been rebuilt with loose fill. It's not technical rock crawling, but one wrong move puts you over the edge into the Hunza River gorge, so slow and deliberate driving matters more than skill here.
How far is the gap between fuel stops on the Gilgit to Sost run?
Gilgit, Karimabad (near Aliabad), and Sost all have fuel — but stations in between are unreliable and often out of diesel. Carry at least 30–40 liters extra if your vehicle drinks fuel at altitude; the elevation gain hits consumption hard and you don't want to be guessing past Passu.
