Edge of the Sky: Climbing Gasherbrum II in Pakistan’s Karakoram
An 8,000-meter bid across the Baltoro to the white throne of the Gasherbrums.
Just after dawn, the pilot banks over a river the color of brushed steel and the window fills with rock and sky. Out the left side, Nanga Parbat holds court; straight ahead, K2’s pyramid shoulders flicker in and out of thin cloud. The Karakoram isn’t shy—it rises fast, speaks plainly, and likes to test who’s listening. If you’re bound for Gasherbrum II, it’s your first handshake with a range that doesn’t whisper.
Trail Wisdom
Respect the Baltoro’s Rhythm
Glacier travel here is slow and uneven—plan conservative daily distances and protect ankles with high, supportive boots and trekking poles.
Acclimatize Like It Matters
Build rest days into the schedule—climb high, sleep low, and be willing to descend if symptoms persist. A disciplined plan beats ambition at 7,000+ meters.
Weather Windows Win Summits
Karakoram storms roll in fast; track forecasts via satcom and be prepared to sit tight. A 24–36 hour lull can be the difference between success and retreat.
Crevasse Vigilance All Day
Rope up where bridges look suspect, probe new snow, and travel early when surfaces are firmer. Afternoon heat weakens snow bridges.

Conservation Note
The Baltoro corridor faces waste-management challenges; use expedition toilet systems and pack out all trash to protect a fragile high-altitude environment.
Gasherbrum II was first climbed in 1956 by an Austrian team led by Fritz Moravec, via the Southwest Ridge, setting the classic line used by most expeditions today.
Seasonal Guide
spring
Best for: Quieter approach trek, Cooler lower-glacier temps
Challenges: Unstable snow bridges, Higher avalanche risk on fresh snow
Early season brings fewer teams on the Baltoro and colder nights; climbing above 7,000 meters is generally premature.
summer
Best for: Primary summit bids, More stable weather windows
Challenges: Intense solar exposure, Afternoon slush and rockfall
June through August is peak season for Gasherbrum II, with the best shot at clear periods for carries and a summit push.
fall
Best for: Crisp views, Lower crowds on the trek out
Challenges: Shorter days, Increasing storms and colder highs
By September, conditions trend colder and less predictable; post-monsoon trekking can be superb, but summit chances drop.
winter
Best for: Advanced expeditions only, Extreme cold training
Challenges: Severe cold, High winds and almost no weather windows
Winter attempts are rare and extremely committing; expect brutal wind chill and complex logistics.
Photographer's Notes
What to Bring
8000-meter Double BootsEssential
Critical warmth and compatibility with automatic crampons for high camps and summit day.
High-Loft Down Suit or Layered Parka SystemEssential
Keeps core temperature stable during long, windy summit pushes above 7,000 meters.
Glacier Sunglasses or Goggles (Category 4)Essential
Prevents snow blindness in high-reflectivity conditions on the Baltoro and upper mountain.
Satellite Communicator (InReach/Iridium)
Reliable weather updates and emergency comms once you leave cell coverage beyond Skardu.
Common Questions
How technical is the standard route on Gasherbrum II?
It’s considered one of the more attainable 8,000ers but still involves crevasse navigation, fixed lines, and 30–45° snow/ice; prior high-altitude climbing experience is essential.
Do I need supplemental oxygen?
Many teams climb GII without bottled oxygen, but some choose to use it above 7,000 m for warmth and margin. Decide based on experience, conditions, and guide recommendation.
What permits are required?
A climbing permit from the Gilgit-Baltistan Tourism Department, trekking permit for the Baltoro/Concordia region, and a liaison officer are typically required.
What is the approach to base camp like?
Expect 6–8 days trekking from Askole across moraine and glacier to Concordia and Gasherbrum Base Camp, with significant elevation gain and rough, uneven terrain.
When is the best time to attempt Gasherbrum II?
June through early August offers the most reliable weather windows for establishing high camps and summit attempts.
Is there cell service on the route?
Coverage drops off after Skardu; beyond Askole there is effectively no service. Teams rely on satellite phones or messengers for communication and weather.
What to Pack
High-altitude double boots for warmth and crampon security; Down suit or layered parka system for summit-day insulation; Category-4 glacier sunglasses to prevent snow blindness; Satellite communicator for weather updates and emergencies beyond Skardu.
Did You Know
The Baltoro Glacier is roughly 63 kilometers long, making it one of the longest non-polar glaciers on Earth and a key gateway to four 8,000-meter peaks: K2, Broad Peak, Gasherbrum I, and Gasherbrum II.
Quick Travel Tips
Book flexible flights to account for weather delays into or out of Skardu; Bring multiple passport photos for permits on arrival; Pack small-denomination rupees for porter tips and village purchases; Expect no ATMs beyond Skardu—carry enough cash for contingencies.
Local Flavor
After the expedition, refuel in Skardu with chapshuro (Balti meat pie) and apricot stew, then wander the restored Shigar Fort for a glimpse into local history. For a celebratory cup, try salty butter tea at a family-run teahouse along the bazaar.
Logistics Snapshot
Closest airports: Skardu (KDU) via Islamabad (ISB). Trailhead: Askole, 6–8 hours by 4x4 from Skardu. Expect no cell service beyond Askole—satellite comms recommended. Permits: Climbing and trekking permits plus a liaison officer are required; arrange through a licensed outfitter.
Sustainability Note
The Karakoram’s high-altitude ecosystems recover slowly—pack out all waste, use blue-bag or barrel toilet systems at camps, and choose outfitters who prioritize porter welfare and low-impact logistics.
