Anni Katri Penttilä (born 22 April 1993, Mikkeli, Finland) is a Finnish mountaineer from Helsinki, who works as a digital marketing entrepreneur and a tour guide in Tanzania and Nepal.
Mountaineering career Penttilä became interested in mountain hiking and climbing at the age of 16 in 2009, when she read an article about the Annapurna Circuit hiking trail in National Geographic. She was able to hike there in 2013. “The place was just as wonderful as I had imagined. We were at an altitude of 5.5 kilometers, with snow-covered mountains all around. I was immediately hooked.” “I was 19 years old when I set myself the goal of climbing Everest before I turn 30,” she told Retki magazine later. After an eight-year project, she reached the summit at the age of 27 as part of the Altitude Junkies group led by Phil Crampton. She became the 19th Finn and the youngest Finnish woman to have summitted Everest.
By May 2026, Penttilä has managed to climb seven eight-thousanders in Nepal and India. Her goal is to climb all 14 eight-thousanders in the future. In the summer of 2025, she planned to climb K2 in Pakistan, i.e. Godwin Austen (8 611 m), and the nearby Broad Peak (8 051 m), both of which are located in the Karakorum Range. She also has the goal of conquering the so-called seven summits as the first Finnish woman. So far, the only Finn known to have achieved this feat is Atte Miettinen.
While preparing for her climbs, Penttilä has also experienced adversity. She broke her humerus in a gym accident in March 2017. Almost at the same time, her knee required surgery. After that, Penttilä had to move around in a wheelchair, and she wondered if the dream of conquering Everest should be abandoned. However, some six months later she managed to conquer Kilimanjaro. While in the mountains, she has managed to avoid problems, apart from occasional symptoms of mountain sickness.
Penttilä has told about her experiences in the mountains as follows:
