The Crown Jewel of the Karakoram
At 8,611 meters on the border of Pakistan and China, K2 is more than a mountain. It is the ultimate test
of high-altitude endurance and technical skill. Known universally as the “Savage Mountain,” it commands
absolute technical precision and mental fortitude.
Blue Sky Treks & Tours invites experienced climbers to join our 2027-28 expedition. Whether you want
to complete all fourteen 8,000m peaks or reach the world's most respected summit, our three decades of
local experience will support your objective.
Key Technical Sections (Abruzzi Spur)
House's Chimney (6,600m) A technical 100ft
rock fissure requiring intense focus and stamina at altitude, leading directly into Camp 2.
The Black Pyramid (7,200m) Situated between
Camp 2 and 3, climbers must navigate a steep, demanding expanse of mixed rock and ice.
The Bottleneck (8,200m) The final crux.
Climbers must traverse a narrow couloir directly beneath towering, unstable seracs before the final
summit push.
50-Day Itinerary
01 Day 1: Arrival in Islamabad, Pakistan
▼
Touch down in Pakistan. Most international flights arrive in Islamabad early in the morning. Our team will meet you in the arrival hall for a private transfer to the hotel to help you recover from jet lag. Once the full team has gathered, we hold a mandatory expedition briefing to discuss logistics, permit formalities, and the climb ahead.
Overnight: 3/4 Star Hotel | Activity: Gear check, briefing, and optional city tour if time permits.
02 Day 2: The Skardu Flight (or Karakoram Highway Drive)
▼
We aim for the scenic 45-minute flight to Skardu (2,230m). This flight is weather-dependent but offers world-class views of Nanga Parbat and the Karakoram giants. If the weather holds, we land in Skardu, the logistics hub of Baltistan. If flights are grounded, we embark on the adventurous drive via the Karakoram Highway to Chilas.
•Key Sight: Nanga Parbat (9th-highest mountain) is visible from the right side of the aircraft.
•Contingency: Drive to Chilas (461km / 8-9 hours) if the flight is cancelled.
03 Day 3: Final Preparations in Skardu
▼
A crucial buffer day for finalizing climbing permits with the tourism department. While we handle the paperwork, you are free to explore Skardu’s rich history. Hike up to the 17th-century Kharpocho Fort for panoramic views of the Indus River, or visit the “Organic Village” to see traditional Balti farming.
•Acclimatization: Gentle walking around town (2,230m).
•Logistics: Final kit check and packing loads for the porters.
04 Day 4: Jeep Safari to Askole
▼
We load into 4×4 jeeps for a rugged 7-hour drive through the Shigar Valley. The road narrows as we enter the Braldu Gorge, eventually leading to Askole (3,000m). This is the “end of the road” and the last permanent settlement you will see for two months.
•Elevation: 3,000m
•Drive Time: ~7 Hours
•Highlight: The transition from paved roads to the raw Karakoram wilderness.
05 Day 5: Askole to Jula (The Trek Begins)
▼
The expedition officially starts on foot. We trek out of Askole, leaving the green fields behind for the arid Braldu valley. We cross the snout of the Biafo Glacier and break for lunch at the green oasis of Korofong. The day ends crossing a suspension bridge over the Dumurdo River to reach Jula Camp.
•Elevation: 3,100m
•Trek Time: 5 Hours
•Terrain: Dusty trails, river crossings, and dry heat.
06 Day 6: Jula to Paiju
▼
We follow the Braldu River upstream. The trail undulates, requiring good footwork. As we approach Paiju (3,380m), the valley widens, revealing the first views of the catastrophic Baltoro Glacier. Paiju is a traditional rest stop with trees and fresh water—the last “green” campsite before hitting the ice.
•Elevation: 3,380m
•Trek Time: 6 Hours
•Key View: First glimpse of the Great Trango Tower and Cathedral peaks.
07 Day 7: Paiju to Khoburtse (Entering the Glacier)
▼
A tough but rewarding day. We climb onto the snout of the Baltoro Glacier. The terrain shifts to loose rock and glacial moraine. We traverse the glacier to its south side and hike to Khoburtse (3,760m). The views here are iconic: the vertical walls of the Trango Towers and Uli Biaho dominate the skyline.
•Elevation: 3,760m
•Trek Time: 7 Hours
•Terrain: Glacial moraine (rock on ice).
08 Day 8: Khoburtse to Urdukas
▼
A shorter day gaining altitude along the lateral moraine. We arrive at Urdukas (4,130m) by lunch. This is a spectacular campsite perched on grassy slopes above the glacier. It offers direct views of the Cathedral Group and Trango Towers across the valley.
•Elevation: 4,130m
•Trek Time: 4 Hours
•Significance: The last campsite with soil/grass; everything after this is ice and rock.
09 Day 9: Acclimatization at Urdukas
▼
Rest is critical here. We spend the day at Urdukas to allow our bodies to adjust to the 4,000m+ altitude. It’s a perfect day for photography, organizing gear, and washing clothes before the push to the high camps.
10 Day 10: Urdukas to Goro II
▼
We descend back onto the Baltoro Glacier and head east. The landscape turns icy and dramatic as we pass Masherbrum (7,800m) and Muztagh Tower. We camp right on the glacier ice at Goro II (4,250m). Nights become significantly colder from here on.
•Elevation: 4,250m
•Trek Time: 7 Hours
•Conditions: Camping on ice (sleeping pads essential).
11 Day 11: Goro II to Concordia (The Throne Room)
▼
Today, we reach one of the most famous locations in mountaineering history: Concordia. This is the confluence of the Baltoro and Godwin Austen glaciers. As you arrive, K2 (8,611m) suddenly reveals itself, rising nearly 4 vertical kilometres from the valley floor. You are surrounded by 8,000m giants: Broad Peak, Gasherbrum IV, and K2.
•Elevation: 4,600m
•Trek Time: 5 Hours
•Highlight: Unobstructed views of K2 and the “Gasherbrum Group.”
12 Day 12: Concordia to Broad Peak Base Camp
▼
We move further up the Godwin Austen Glacier. We pass Broad Peak Base Camp (5,000m). Depending on the team’s pace, we may camp here or push through. This area serves as the staging ground for both Broad Peak and K2 climbers.
•Elevation: 5,000m
•Trek Time: 4 Hours
13 Day 13: Arrival at K2 Base Camp
▼
The final leg. We trek to the foot of the Savage Mountain. En route, we pause at the Gilkey Memorial, a poignant site honouring climbers who have lost their lives on K2. We arrive at K2 Base Camp (5,150m), your home for the next six weeks.
•Elevation: 5,150m
•Trek Time: 6 Hours
•Objective: Establish Base Camp operations.
14-42 Days 14 – 42: Climbing Period (The Abruzzi Spur)
▼
For the next 28 days, we engage in the siege tactics required for K2.
•Rotations: Climbers will move between Base Camp, Camp 1 (6,050m), Camp 2 (6,700m), and Camp 3 (7,200m) to acclimatize and stock supplies.
•The Route: We typically follow the Abruzzi Spur (Southeast Ridge), navigating the House’s Chimney and the Black Pyramid.
•The Summit Push: We wait for a distinct weather window to push to Camp 4 (Shoulder) and make the final bid for the summit (8,611m) through the Bottleneck.
•Logistics: Base Camp staff provide meals, weather reports via satellite, and medical support throughout this period.
43 Day 43: Clean Up & Trek to Goro II
▼
After the expedition wraps up and the mountain is cleaned of our debris, we begin the return trek down the glacier to Goro II. The oxygen-rich air feels incredible as we drop in altitude.
•Overnight: Goro II Camp
44 Day 44: Trek to Khorbtuse
▼
We continue down the Baltoro Glacier, carefully navigating the moraine before reaching Khorbtuse for the night.
•Overnight: Khorbtuse Camp
45 Day 45: Trek to Mon Camp
▼
Leaving the higher glacier behind, we continue along the return trail to Mon Camp, where we spend the night.
•Overnight: Mon Camp
46 Day 46: Trek to Korphon
▼
We follow the valley trail to Korphon for our final night in camp, marking the expedition’s safe return with our porters and support staff.
•Overnight: Korphon Camp
47 Day 47: Korphon to Skardu
▼
We leave Korphon and travel back to Skardu. Arriving in Skardu means hot showers, soft beds, and fresh food at the hotel.
•Drive Time: 7 Hours
48 Day 48: Fly to Islamabad
▼
We aim for the morning flight back to the capital. Upon arrival, we transfer to the hotel. The rest of the day is free for carpet shopping or relaxing.
•Contingency: If the flight is cancelled, we will begin the road journey via the KKH.
49 Day 49: Reserve Day / Sightseeing
▼
Used as a buffer for flight cancellations. If we flew yesterday, today is a dedicated sightseeing day in Islamabad (Faisal Mosque, Daman-e-Koh viewpoint), followed by a farewell dinner.
50 Day 50: International Departure
▼
Transfer to Islamabad International Airport. End of the K2 Expedition. Safe travels!

Verified Expedition Reviews
★★★★★
"I highly recommend Blue Sky Treks as a tour operator for any expedition planning to climb in Pakistan.
As our agency for the K2 North Ridge Expedition, they provided excellent services. The staff were strong
and reliable, the food was of excellent quality, and transportation was safe and on time. This was
definitely the most satisfied I have been with an agency in 5 trips to Pakistan."
