All stories
A month-by-month look at weather, crowds and glacier conditions on the Baltoro — and why we prefer late July.
The K2 Base Camp trek has a short season. Snow closes the upper Baltoro for most of the year, and the summer window between late June and the end of August is when the trail is most reliable.
June: quiet but snowy
Early-season groups enjoy empty campsites and fresh snow on the peaks, but the upper glacier can still be soft and Gondogoro La is often not yet open.
July: the classic window
July brings the most stable weather and firm trails. Expedition teams are on the mountains, giving base camps a lively atmosphere.
August: warm days, fewer people
By August many expeditions have left. Days are warm, though afternoon streams on the glacier run higher.
Whatever month you choose, build in spare days. Skardu flights and mountain weather both like to keep their own schedule.
- Best overall: mid-July to mid-August
- Best for solitude: late June
- Best for Gondogoro La: late July
