Sirbaz Khan Becomes First Pakistani to Summit All 14 Eight-Thousanders Without Supplemental Oxygen

Pakistani mountaineer Sirbaz Khan has become the first Pakistani to summit all 14 of the world’s 8,000-metre peaks without the use of supplemental oxygen, a rare and elite achievement in high-altitude mountaineering.

He completed this feat on May 18, 2025, by reaching the summit of Kangchenjunga (8,586m), the third-highest mountain in the world, without oxygen support.

Sirbaz’s journey began in 2017 with his successful ascent of Nanga Parbat. Over the years, he climbed all 14 eight-thousanders, including K2, Lhotse, Broad Peak, Manaslu, Annapurna, Everest, Gasherbrum I and II, Dhaulagiri, Makalu, Cho Oyu, and Shishapangma.

Although he had summited all 14 peaks by October 2024, two of those climbs (Annapurna and Kangchenjunga) were initially completed with bottled oxygen. To achieve the no-oxygen distinction, he re-climbed these two peaks in 2025 without supplemental oxygen, thus officially entering the ranks of fewer than 25 climbers worldwide who have summited all 14 eight-thousanders without oxygen.

This accomplishment places Sirbaz Khan among an elite group of mountaineers globally and highlights his extraordinary physical endurance, skill, and mental resilience. His achievement is celebrated as a symbol of Pakistani resilience and courage and is expected to inspire future generations of climbers in the region.

Sirbaz Khan’s historic accomplishment marks a significant milestone in Pakistani mountaineering history and the global climbing community.
