Khunjerab Pass (4,693m): The World's Highest Paved Border Frontier

1. The Climax of the Karakoram Highway: The Eighth Wonder

Constructed through decades of superhuman engineering between 1959 and 1979 by Pakistani and Chinese engineers—sacrificing over a thousand lives to dynamiting, landslides, and altitude sickness—the highway across Khunjerab Pass transformed ancient Silk Road caravan trails into an asphalt marvel. The word Khunjerab is derived from ancient Wakhi words meaning 'Valley of Blood', referring to historical raids by Central Asian bandits or the red hue of mineral-rich scree slopes flanking the pass.

Today, as your vehicle crests the final gentle switchbacks through the sweeping alpine meadows of Gojal, the stark, treeless Karakoram plateau opens into a boundless amphitheater of ice and rock. At Zero Point, the dramatic arched concrete Pakistan-China Friendship Gate rises proudly against the azure sky, marking the peaceful frontier between two neighboring superpowers.

2. Khunjerab National Park: A Sanctuary for Endangered Mountain Wildlife

Established in 1975 at the personal initiative of Prime Minister Zulfikar Ali Bhutto and international conservationist Dr. George Schaller, the Khunjerab National Park encompasses over 2,200 square kilometers of pristine alpine tundra. It was created specifically to protect one of the planet's rarest and most magnificent mammals: the spiral-horned Marco Polo Sheep (Ovis ammon polii).

While driving through the upper park limits along the Dih and Koksil streams, observant travelers frequently spot:

• Himalayan Ibex: Graceful wild mountain goats sporting long, curved scimitar horns, often seen grazing in herds along near-vertical rock ledges above the asphalt.
• Golden Marmots: Chubby, vocal high-altitude rodents that stand on their hind legs and whistle loudly across the tundra pastures from May through September.
• Domestic & Wild Yaks: Shaggy, massive high-altitude bovines tended by local Wakhi pastoralists, grazing placidly amidst melting snowdrifts.
• Apex Predators (Protected): Snow leopards, Tibetan wolves, and Tibetan red foxes, which hunt ibex across the higher glacial screes.

3. The World's Highest ATM (Guinness World Records)

One of the most famous and photographed oddities of Khunjerab Pass is the solar- and wind-powered National Bank of Pakistan (NBP) ATM, installed at 4,693 meters in November 2016. Officially certified by the Guinness Book of World Records as the highest operational automated teller machine on Earth, it provides cash withdrawal services to travelers, border guards, and commercial truck drivers even in sub-zero alpine conditions. Taking a commemorative selfie while withdrawing Pakistani rupees at nearly 15,400 feet has become an essential bucket-list tradition for tourists.

4. Day-Trip Itinerary: Karimabad or Passu to Khunjerab Pass

Visiting Khunjerab Pass is typically conducted as a scenic, high-value day excursion starting from Central or Upper Hunza:

• 07:30 AM (Karimabad / Passu Departure): Depart early morning along the smooth Karakoram Highway. Travel past the cathedral spires of Passu Cones, Batura Glacier, and the terraced orchards of Khyber village.
• 09:00 AM (Sost Customs Checkpoint): Pass through Sost, the bustling dry port town handling cross-border commercial trade. Stop briefly at the Khunjerab National Park entry post to pay the conservation entry fee.
• 10:30 AM (Dih Checkpost & Wildlife Corridor): Ascend into the rocky canyon past Dih, the final permanent park ranger outpost. Watch for Himalayan ibex jumping across the roadside crags. Notice the gradual thinning of alpine air as elevation climbs past 3,800m.
• 11:45 AM (Arrival at Khunjerab Pass Zero Point, 4,693m): Arrive at the expansive, snow-fringed plateau. Photograph the iconic China-Pakistan Border Gate, shake hands with border guards across the line, withdraw a record receipt from the World's Highest ATM, and marvel at grazing yaks. Enjoy 45 to 60 minutes taking in the crisp, razor-thin mountain air.
• 01:00 PM (Descent to Sost / Passu): Begin the scenic descent back into lower Gojal. Stop at Sost for a warm lunch of authentic local Wakhi dishes or Chinese noodles.
• 04:00 PM (Return to Karimabad): Return to your hotel in Karimabad or Attabad Lake for a relaxing evening and hot tea.

5. High Altitude Physiology & Cold Protocols

At 4,693 meters, the atmospheric pressure is nearly half that at sea level. The air contains significantly less oxygen per breath. Trekkers and tourists should heed the following medical guidelines:

6. Seasonal Opening Windows & Border Dynamics

Under the bilateral border trade agreement between Pakistan and China, Khunjerab Pass operates under defined seasonal schedules:

• April 1st to November 30th (Border Open Window): The pass and border gates are open for official vehicular transit, international passenger bus services (between Sost and Tashkurgan/Kashgar), and tourist excursions. High summer (June-August) offers comfortable sunny days with daytime temperatures between 8°C and 14°C at the pass.
• December 1st to March 31st (Winter Snow Protocol): The border is officially closed to regular commercial traffic due to heavy Karakoram blizzards, sub-zero temperatures (dropping to -30°C), and avalanche hazards. However, special trade convoys or short winter tourism windows are occasionally permitted by local authorities depending on snow-clearing operations.
