A 62 km river of ice cutting through the Karakoram, the approach corridor to K2, Broad Peak, and the Gasherbrum peaks, and one of the most spectacular glacier treks on Earth.
The Baltoro Glacier is 62 km of moving ice in the heart of the Karakoram, the highway that carries every climber and trekker toward K2, Broad Peak, Gasherbrum I, Gasherbrum II, and Concordia. Walking the Baltoro is not optional for anyone heading to the great peaks; it is the approach, and the approach itself is one of the world's great wilderness journeys. The glacier surface is rugged moraine, loose rock and ice chunks, and the trekking route follows its lateral moraines through an amphitheatre of 8,000 m peaks that changes scale with every kilometre.
Why go
Day 1 from Askole reaches Jhola (camping on the river bank). Day 2 crosses the river and enters the Braldu Gorge to Paiju, the last green campsite before the glacier. Day 3 reaches Liligo; Day 4 the Baltoro snout at Khoburtse. From here trekkers walk on or beside the glacier all the way to Concordia (Days 5-6). The route is demanding but non-technical.
The Baltoro surface is heavily covered in moraine, loose rocks from the surrounding mountains deposited by glacial movement. Trekking is on the margins where possible, and on the moraine surface when the route requires. Ice pinnacles (seracs) and meltwater streams cross the route. No crampons needed below Concordia in summer conditions.
A Restricted Area Permit is required for the K2 base camp trek, obtainable through licensed Pakistani tour operators. Foreign trekkers must be with a registered guide. Porters from Askole carry all supplies, the porter economy is the backbone of the Baltoro. GreenPak works with experienced Karakoram operators and can arrange full logistics.
Planning tip
Best Time to Visit, June to August. Snow covers the approach in spring; autumn can bring early storms. Most expeditions start from Askole in late May or June.
Getting there, 4-6 days on foot from Askole village, accessible by jeep from Skardu (4-5 hours on a rough track). Skardu is reached by daily PIA flights from Islamabad (1 hour) or a 2-day road journey via the Karakoram Highway.
Allow, The K2 Base Camp trek via Concordia is 16-20 days return from Skardu. Shorter itineraries reaching the glacier snout only are possible but uncommon, most trekkers who commit to the approach go the full route.
Straight-line distance from Baltoro Glacier, within 30 km.
