Hey there, I’m Jenni. Raised in Sweden but born in the Alps.

Since 2020, Chamonix – at the heart of the French Alps – has been the place I call home. The mountains here are my playground, my safe space, my teacher. It is in this place that my curiosity for the mountains quickly grew into an intense passion when I first arrived in June 2020.

Nature and I have always belonged together, from the time I was a little girl roaming the Swedish forests looking for mushrooms, blueberries, trolls and building makeshift huts, to now – climbing some of the highest and most technical peaks of Europe. A lot has changed, but at my core the little girl inside has never left: her bottomless curiosity, yearning for adventure, and never-ending determination to find out what’s hiding behind the next corner.
