If you have ever looked at a map of Pakistan and traced the thin line running from Punjab all the way up to the Chinese border, you were looking at one of the most remarkable roads ever built by human hands, the Karakorum Highway. Having traveled this route, spoken to locals along the way, and dug into its history, I can say with confidence: no photograph or description fully prepares you for it.
This guide covers everything you need to know before driving, riding, or touring the KKH, from its history and construction to the best stops, safety tips, and travel advice for first-timers.
What Is the Karakorum Highway?
The Karakorum Highway (KKH) is a 1,300-kilometer (approximately 808-mile) two-lane international highway that runs from Hassan Abdal in Punjab, Pakistan, to Kashgar in the Xinjiang region of China. It is officially recognized as the highest paved international highway in the world, reaching its highest point at the Khunjerab Pass, a border crossing at 4,693 meters (15,397 feet) above sea level.
The highway is also known as the "Friendship Highway" because it was jointly constructed by Pakistan and China. Construction began in 1966 and was completed in 1978. The road was officially opened to the public in 1986. Roughly 900 Pakistani and Chinese workers lost their lives during construction — a sobering reminder of the human cost behind this engineering achievement
Today, the KKH serves three major purposes:
- Trade route between Pakistan and China under the China-Pakistan Economic Corridor (CPEC)
- Tourism corridor connecting some of the most scenic areas of Gilgit-Baltistan.
- Strategic link between the two allied nations
A Brief History of the Karakorum Highway
The KKH was not built on empty land. It follows parts of the ancient Silk Road, the historic trade network that once connected China, Central Asia, Persia, and the Mediterranean world. Merchants, monks, and explorers traveled these mountain paths for centuries, carrying silk, spices, and ideas.
When Pakistan and China decided to build a modern paved road along this route in the 1960s, engineers faced conditions unlike almost any other road project in history:
- Temperatures drop to -20°C in winter.
- Rock faces that could not be blasted with conventional equipment.
- Glaciers, rivers, and loose shale that shifted constantly
- Altitude sickness affects workers at high elevations.
The project took over 20 years and required the expertise of thousands of engineers, soldiers, and civilian laborers from both countries. Many consider it the greatest road construction achievement since the Roman Empire built its network of highways.
Why the KKH Is Famous Worldwide
The Karakorum Highway is famous for several distinct reasons, and it is important to separate fact from tourism hype:
1. Engineering Achievement:
The road crosses three of the world's great mountain ranges: the Himalayas, the Karakoram, and the Hindu Kush. Building a paved, two-lane road through this terrain was considered impossible by many engineers at the time.
2. Scenic Beauty:
The highway passes through landscapes that shift dramatically over short distances from dry rocky plains near Besham to lush green valleys in Hunza, turquoise lakes near Gojal, and snow-covered passes near Khunjerab. The variety is genuinely difficult to find anywhere else in the world.
3. Cultural Diversity:
Along the route, you pass through communities speaking Hindko, Shina, Burushaski, Wakhi, and Khowar languages that are entirely distinct from one another. The cultural traditions, food, music, and architecture change noticeably as you gain altitude.
4. Danger and Adventure:
The KKH is listed among the world's most dangerous roads. This is not marketing; the road genuinely has sections with no barriers above sheer drops, regular rockfalls, and unpredictable weather. For adventure travelers, this is a legitimate draw.
Major Cities and Towns on the KKH Route
Here is a breakdown of the major stops along the highway, from south to north:
Hassan Abdal (Starting Point):
A historic town in Punjab, Hassan Abdal is the official southern starting point of the KKH. It is home to the Panja Sahib Gurdwara, one of the holiest sites in Sikhism, attracting pilgrims from around the world.
Abbottabad:
A clean, green hill town at roughly 1,256 meters elevation. Abbottabad is a good place to rest before the highway gets serious. The weather here is mild compared to the plains, and it has decent hotels and restaurants.
Besham:
Besham is a commercial town on the banks of the Indus River. It marks the point where the highway truly begins to follow the Indus gorge the scenery becomes dramatic from here onward.
Chilas:
Chilas sits at the junction of the Karakoram Highway and the road to Fairy Meadows, the base camp approach to Nanga Parbat, the ninth-highest mountain in the world. The town is also known for thousands of ancient rock carvings and inscriptions left by travelers on the Silk Road.
Gilgit:
Gilgit is the administrative capital of Gilgit-Baltistan and the largest city on the KKH north of Abbottabad. It has a functional airport, decent hospitals, a bazaar, and serves as the hub for side trips to Yasin Valley, Ghizer, and the road toward Skardu and K2.
Hunza Valley
Arguably, the most famous destination on the entire highway. Hunza is known for:
- Baltit Fort — a 700-year-old fort above Karimabad town, recently restored
- Altit Fort — even older, with stunning views of the valley
- Cherry and apricot blossoms in spring (late March to April)
- The famous Eagle's Nest viewpoint, offering panoramic views of Rakaposhi, Ultar Sar, and Diran peaks.
Attabad:
Lake Attabad was formed in January 2010 when a massive landslide blocked the Hunza River, submerging the village of Attabad and several others. The resulting lake stretches about 21 kilometers and has a striking turquoise color caused by glacial silt. Boat rides are available, and the area now has guesthouses and a small tourism economy. The lake is a reminder that the landscape here is still actively changing.
Passu:
A quiet village north of Attabad, Passu is famous for the Passu Cathedral, a row of sharp, cathedral-like granite spires that rise steeply from the valley floor. The area has some excellent trekking routes, including the Passu Glacier walk. The famous Hussaini Suspension Bridge, one of the most photographed and nerve-testing rope bridges in the world, is a short walk from the village.
Sost:
Sost is the last Pakistani town before the Chinese border. It has a dry port for customs clearance and basic guesthouses. The landscape here becomes more arid and remote. From Sost, the road climbs sharply toward Khunjerab.
Khunjerab Pass (4,693 m)
The Khunjerab Pass marks the Pakistan-China border. The name comes from the Wakhi language, meaning "Valley of Blood", a reference to the historical raids that took place here, not the scenery, which is actually open, cold, and quiet. The pass is open to tourists from May 1 to November 30 each year. Snow leopards, Marco Polo sheep, and Tibetan wolves inhabit the surrounding national park.
Top Experiences on the Karakorum Highway
Trekking Near Passu and Gulmit
Several accessible day treks start from villages around Passu and Gulmit. The Boiber Glacier and Shimshal Valley treks are popular with intermediate hikers.
Visiting Baltit and Altit Forts in Hunza
Both forts have been restored by the Aga Khan Cultural Service and are open to visitors with a small admission fee. Inside, guides explain the political history of the Hunza State and its rulers.
Rock Carvings at Chilas and Thor
Over 50,000 ancient rock carvings have been documented along the KKH between Chilas and Shatial. These include Buddhist stupas, ibex figures, and inscriptions in Kharoshthi and Brahmi script — a UNESCO-recognized heritage site.
Fairy Meadows (Side Trip from Raikot Bridge)
About 4 hours from Chilas, a rough jeep track and a 3-hour walk lead to Fairy Meadows — an alpine meadow with a direct view of the south face of Nanga Parbat. Camping here on a clear night is an experience worth the effort.

Safety Tips for Traveling the KKH
The risks on this road are real and worth respecting:
- Check road conditions before departure. NDMA Pakistan and local WhatsApp groups maintained by guesthouse owners are reliable sources for road closure updates.
- Drive during daylight only. Many sections lack road markings, barriers, and adequate night visibility.
- Carry a vehicle emergency kit. Include a spare tire, a tow rope, a first-aid kit, warm clothing, and basic food.
- Altitude sickness is genuine above 3,000 m. Ascend gradually. If you experience severe headache, nausea, or difficulty breathing, descend immediately.
- Avoid the highway during heavy rain. Rockfalls and flash floods happen quickly and without warning.
- Fuel up at every opportunity. Fuel stations become sparse north of Gilgit.
Local Culture and Food Worth Trying
The communities along the KKH — Hazara, Kohistani, Shina-speaking Gileeti, Burusho of Hunza, Wakhi of Gojal — each have distinct traditions. A few things worth experiencing:
- Chapshuro — a meat-filled flatbread common in Hunza and Gilgit
- Mulberry wine and dried apricots from Hunza orchards
- Polo matches in Gilgit (the Shandur Polo Festival in July is a major event)
- Local gemstones — the region produces rubies, aquamarine, and tourmaline; reputable shops exist in the Gilgit bazaar
Locals in this region are known for their hospitality. In smaller villages, being invited for tea is common and genuine. However, respect local customs: dress modestly, ask before photographing people, and be mindful that some communities are conservative in their practices.
The KKH and CPEC: Economic Importance
Since the launch of the China-Pakistan Economic Corridor (CPEC) in 2015, the KKH has regained strategic and economic importance. The highway forms the backbone of the western route connecting Gwadar Port in Balochistan to Kashgar in China's Xinjiang province, a distance of roughly 3,000 km.
Upgrades to the highway have been ongoing, including road widening, tunnel construction, and the addition of rest areas and border facilities at Khunjerab. The economic activity generated along this corridor has brought new businesses, improved infrastructure, and increased tourism to areas that were previously very isolated.
Final Thoughts:
If you go, go prepared, go respectfully, and take the time to stop in the small villages rather than rushing between the famous landmarks. The real character of this highway lives in the places that do not yet appear in tourist brochures.
