Climbing Season on the Baltoro: K2, Broad Peak and the Gasherbrums in 2026

Four of the world’s fourteen 8,000-metre peaks stand within sight of one another at the head of the Baltoro Glacier: K2 (8,611 m), Broad Peak (8,051 m), and the Gasherbrums I and II (8,080 m and 8,035 m). The 2026 climbing season is open now — the weather window on these mountains runs roughly late June through August, and the teams are already walking in from Askole.

This is the heart of the Karakoram, the densest concentration of high peaks anywhere on Earth. If you are planning an expedition this year, here is the honest picture of what the season looks like, how you get in, and what these mountains actually demand — from a Skardu team that handles logistics on the Baltoro every summer.

The 8000ers of the Baltoro

Walk to Concordia, the junction where the Baltoro and Godwin-Austen glaciers meet, and you stand in what early explorers called the Throne Room of the Mountain Gods. K2 fills the northern sky. Broad Peak sits a short distance east, and behind it the Gasherbrum group — including Gasherbrum I (Hidden Peak) and Gasherbrum II — rises along the Chinese border. No other place on Earth puts four eight-thousanders this close together.

Each peak draws a different climber. Gasherbrum II (8,035 m) is widely regarded as one of the more attainable 8000ers and is often a climber’s first. Broad Peak (8,051 m) is a serious objective with a long, deceptive summit ridge. Gasherbrum I (8,080 m), the Hidden Peak, is more technical and remote. And K2 (8,611 m) — the second-highest mountain on Earth — is in a league of its own, with a fatality history that demands genuine experience.

The 2026 season window

The Karakoram has a short, sharp climbing season. The jeep road to Askole opens properly once the spring snow gives, base camps are established through June, and most teams use late June and early July for acclimatisation rotations between camps. The summit window usually lands in mid-to-late July, when the weather is most settled, though strong teams summit into early August. By September the season is closing.

For 2026 specifically, expeditions on Gasherbrum II are already getting underway, and fixed K2 departures run through the second half of summer. If you want a place on a 2026 expedition, this is the moment to lock logistics — permits and liaison-officer arrangements take time. Message us for current dates and availability rather than relying on last year’s calendar.

Getting in: Skardu to base camp

Every Baltoro expedition starts in Skardu (~2,500 m), reached by a short flight from Islamabad or the long overland drive. From Skardu it’s a rough 4×4 jeep to Askole (roughly 7–9 hours on a genuinely rough track), the last village before the wilderness. From there you walk — days up the Baltoro Glacier, a 63-kilometre river of ice, past Paiju and Urdukas to Concordia, then on to the individual base camps. Our Baltoro Glacier guide covers the approach in detail, and the K2 Base Camp trek guide walks the same route up to K2 BC at around 5,150 m.

This walk-in is itself a major undertaking. Porters carry the loads, but the days are long, the glacier is broken and exposed, and you are already gaining altitude. Many climbers underestimate the approach and arrive at base camp tired. We don’t.

The four peaks, honestly

There is no easy 8,000-metre mountain. But there is a real spread of difficulty and risk across the Baltoro giants, and choosing the right one matters more than ego does.

If you are stepping up to your first 8000er, Gasherbrum II is the usual starting point, and a trek like Gondogoro La or K2 Base Camp is a sensible way to test yourself at altitude on the same glacier system first.

Acclimatisation and the real risk

Altitude is the variable that decides most expeditions, and it cannot be rushed. On these peaks you climb high and sleep low across repeated rotations over weeks — there is no shortcut. The thin air, the cold, and the objective hazards of the Baltoro (crevasses, séracs, sudden weather) are real, and pretending otherwise gets people hurt. Read our acclimatisation guide before you commit, and our Karakoram gear list for what the mountain demands.

Permits, liaison officer and visa

K2, Broad Peak and the Gasherbrums sit in a restricted zone, so the paperwork is more involved than a standard trek. You’ll need a climbing permit and royalty paid to the Government of Pakistan, a liaison officer assigned to the expedition, and the correct Trekking & Mountaineering visa — distinct from the tourist e-Visa most travellers use. Rules, royalty figures and processing times change year to year, so confirm the current requirements with us early; our Pakistan visa guide is a starting point, not the last word.

Climbing the Baltoro 8000ers with Karakoram Venture

We are based in Skardu, and our guides and high-altitude staff come from the Balti communities that have lived under these mountains for generations — not a broker handing you to a stranger at the airport. Every expedition runs with a real safety system, our own logistics on the glacier, and a fair price that comes from local infrastructure rather than from cutting the things that keep you alive. Local hands, real safety, fair price. If you’re flying into Skardu to start, our Skardu travel guide covers the gateway.
