The expedition is attempting the first ascent of Batura Sar in winter.
The undertaking is part of the Polish Winter Himalaya programme and is intended to prepare the climbers for an attempt to conquer K2 again in winter, planned for the end of this year, Poland’s IAR news agency reported.
Poland’s previous expedition to K2, which is located on the China-Pakistan border, ended without success at the beginning of 2018.
Batura Sar is a summit 7,795 metres above sea level.
Piotr Tomala, head of the Polish Winter Climbing programme and of the expedition, said: “The mountain is far from civilization.”
Tomala added: “We will be absolutely alone there. That's the goal: to build camps on our own, to use our own harnesses on the mountain and learn to function in these conditions".
Eight climbers will take part in the expedition. Tomala said: “The team includes young climbers who may be shortlisted for the K2 lineup in winter.”
The expedition is expected to last two months.
