Slovak mountaineer Lenka Poláčková has made history by becoming the first Slovak woman to climb K2 (8,611 m), the world’s second-highest mountain, this evening, August 11, 2025, Pakistan Time, according to her GPS tracker.

Poláčková reached the summit via the Abruzzi Spur route in stable but challenging conditions. She was attempting to climb the mountain without using supplementary oxygen, although details of her climb are yet to come.

This achievement follows her 2024 climb, where she became the tenth woman in history—and the first from Slovakia to scale Mount Everest without using supplementary oxygen. Earlier that year, she achieved the women’s speed record on Aconcagua (6,961 m), reaching the summit in 6:19:23 and returning base camp-to-base camp in 8:17:34.
