Expedition Overview: The Journey to the Top

The Gasherbrum I Expedition takes you deep into the Karakoram. While many operators only issue permits, Blue Sky Treks & Tours provides a fully supported logistical ecosystem.

The Logistics

We have organized high-altitude expeditions in Pakistan for decades. Our service includes full-board logistics up to Base Camp. From your arrival in Islamabad to your final descent, we handle bureaucracy, domestic flights, jeep transport, and porter management.

The Approach

The journey starts in Skardu, the gateway to the giants. After gathering supplies, you travel by 4×4 jeep to Askoli, the last village before the trek. From there, the route follows the Baltoro Glacier, a moving river of ice, to Base Camp. Along the way, the trek passes the Trango Towers’ spires and Masherbrum’s bulk, aiding acclimatization.

The Food Philosophy

We believe calories equal summit success. Our Base Camp chefs prepare nutritious, high-energy meals with fresh meat and vegetables to help your body recover after rotation rounds.

Technical Climbing Details & Route Strategy

Gasherbrum I is often climbed in conjunction with Gasherbrum II, as they share a Base Camp.

G1 is more demanding than Gasherbrum II. The most common route, the North West Face, requires navigating the Gasherbrum Icefall, then steep snow slopes and mixed climbing sections.
The Camps:
- Base Camp: Located on the Abruzzi Glacier (shared with G2).
- Camp 1 (5,900m): Accessed via the Gasherbrum La and icefall.
- Camp 2 (6,400m): Situated above the difficult “Japanese Couloir.”
- Camp 3 (7,200m): The springboard for the summit push.
Many strong climbers attempt both Gasherbrum I and II in one season, since they share a Base Camp. If you are interested in the ‘Gasherbrum Double,’ contact us for custom royalty fee arrangements.

Ready to Climb Hidden Peak?

Gasherbrum I is a true test for seasoned alpinists. Blue Sky Treks & Tours manages every detail on the ground so you can focus on your climb.

Day 1: Arrival in Islamabad

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.

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 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.

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.

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.

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.

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.

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).

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.

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.

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).

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.”]

Day 12: Concordia to Gashabrum Base Camp

Rise early to witness one of the planet’s most iconic sunrises, watching the first light hit the sheer triangular face of K2 and the summits of the surrounding giants. After breakfast, we bid farewell to the “Throne Room” of Concordia. Instead of turning north toward K2, we head south, stepping onto the immense Upper Baltoro and Abruzzi Glaciers.

The route offers a stunning change of perspective. As we navigate the white sails of ice and glacial moraine, the views open up toward Chogolisa (Bride Peak) and Baltoro Kangri (Golden Throne). We eventually reach the Gasherbrum Sanctuary, a massive glacial amphitheater that serves as the shared Base Camp for both Gasherbrum I and II.

Elevation: 5,150m (16,896 ft)
Trek Time: 4 – 5 Hours
Highlight: Walking away from the crowds of K2 into the stunning, secluded sanctuary of the Gasherbrums, with direct views of the “Hidden Peak” (G1).
Accommodation: Full-service Camping (Base Camp Setup)
Meals: Breakfast, Lunch, Dinner

Days 13 – 37: Climbing Period

For the next 29 days, we engage in the siege tactics required for Broad Peak.

Climbing Strategy & Route Details

Rotations: To prepare for the death zone, the team will complete a series of acclimatization rotations. This process includes moving between Base Camp and higher camps, Camp 1 (approx. 6,000m) and Camp 2 (approx. 6,400m), to adapt to altitude and transport essential gear to the upper mountain.
The Route: We will follow the standard West Ridge. The ascent starts with a steep couloir to Camp 1, then continues through mixed snow and rock sections to Camp 2. Beyond Camp 2, the route crosses snowfields toward Camp 3 (approx. 7,000m), located just below the Col.
The Summit Push: Once a stable weather window is confirmed, we will begin our summit attempt from Camp 3. The ascent includes climbing to the Col (7,800m), followed by a long ridge traverse. Climbers will pass the Rocky Summit (Fore Peak) and continue along the exposed ridge to reach the True Main Summit at 8,047m.
Logistics: Broad Peak Base Camp will serve as our command center. Our staff will provide nutritious meals, real-time satellite weather updates, and continuous communications support to help climbers stay healthy and rested throughout the expedition.

Day 38: Clean Up & Trek to Khoburtse

After the expedition wraps up and the mountain is cleaned of our debris, we begin the long descent. With acclimatized bodies, we cover ground quickly, bypassing Concordia and Goro II to reach Khoburtse or Urdukas in a long push. The oxygen-rich air feels incredible as we drop in altitude.

Target: Khoburtse (3,560m)
Duration: 7-8 Hours (Downhill)

Day 39: Trek to Paiju

We continue down the glacier, navigating the Baltoro moraine. We often have to take a detour around the Liligo Glacier, which is active and surging. We end the day back at the green trees of Paiju.

Elevation: 3,380m
Trek Time: 5 Hours

Day 40: Trek to Jula

Leaving the glacier behind completely, we follow the river valley back to Jula. The temperatures will feel surprisingly warm compared to the summit.

Elevation: 3,170m
Trek Time: 7 Hours

Day 41: Trek to Askole (Celebration Day)

The final walk. We retrace our steps to Askole village. This night is special—we host a “tipping ceremony” and party with our dedicated porters and support staff to celebrate the expedition’s safe return.

Elevation: 3,050m
Trek Time: 3-4 Hours

Day 42: Drive to Skardu

We board the jeeps for the bumpy ride back to civilization. Arriving in Skardu means hot showers, soft beds, and fresh food at the hotel.

Drive Time: 7 Hours

Day 43: 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.

Day 44: 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.

Day 45: International Departure

Transfer to Islamabad International Airport. End of the Gashabrum-1 Expedition. Safe travels!
