Polish climber Piotr Krzyżowski has summited Manaslu (8,163 m), the world’s eighth-highest mountain, this morning, September 25, 2025, marking his ninth eight-thousander climbed without the use of supplementary oxygen or Sherpa support.

Krzyżowski reached the summit in alpine style, continuing his quest to climb all 14 of the world’s highest peaks under strict no-O₂, no-Sherpa rules. His GPS tracker confirmed the successful ascent, though further details of his climb are still to follow.

This ascent comes just months after another major success. On May 10, 2025, at 8:55 a.m. Nepal time, Krzyżowski stood on the summit of Makalu (8,485 m), the world’s fifth-highest peak, once again without bottled oxygen or high-altitude support.

His achievements include his bold double ascent in spring 2024, when he summited Lhotse (8,516 m) on May 21 and Everest (8,848.86 m) on May 23, completing both climbs within 48 hours in pure alpine style. Such a back-to-back ascent of these two giants without oxygen has been achieved by only a handful of mountaineers in history.

For the 46-year-old lawyer from Poland, who also serves as a mountain rescuer in his home country, these climbs add to an already impressive résumé. After a winter ascent of Khan Tengri (7,010 m) in Kyrgyzstan in 2019, Krzyżowski turned his sights to the Himalaya and Karakoram. He summited Gasherbrum II in 2021, Broad Peak and K2 in 2022, and in the summer of 2023 completed all five of Pakistan’s eight-thousanders by scaling Nanga Parbat and Gasherbrum I, all without using supplementary oxygen.

With nine of the 14 eight-thousanders now behind him, each climbed without bottled oxygen or Sherpa support, Piotr Krzyżowski is steadily establishing himself as one of the strongest independent Himalayan climbers of his generation.
